Solar pool covers help reduce heat loss and evaporation, but the right choice depends on your pool dimensions, how often you remove the cover, and whether you prefer easier handling or thicker material. My best overall pick is the BigXwell Heavy-Duty 18 x 36 ft, 16-mil cover, which pairs a common large-pool size with a thicker build. The VEVOR 32 x 16 ft, 16-mil cover is a strong alternative for a medium rectangular pool, while the VEVOR 40 x 20 ft, 12-mil cover suits buyers who need broad coverage and want a thinner option. Across this lineup, the main tradeoff is between coverage, thickness, and the effort required to handle and trim a cover. Read on for the full comparison, fit advice, and picks for different pool sizes and priorities.

Key Takeaways
Thickness and pool size are separate decisions: The lineup includes 12- and 16-mil covers in multiple dimensions, so a thicker option is not automatically the right fit if its listed size does not match your pool.
Several 16 x 32 ft choices make direct comparison easier: VEVOR, Real Relax, and BigXwell each offer a 16-mil option at this size, while BigXwell also has a 12-mil version for buyers weighing thickness against handling.
The 18 x 36 ft and 20 x 40 ft covers target larger pools: BigXwell’s larger 16-mil formats provide options for buyers whose pool dimensions rule out the more common 16 x 32 ft and 24 x 12 ft choices.
VEVOR offers the broadest size-and-thickness spread in this lineup: Its options include 24 x 12, 28 x 14, 32 x 16, and 40 x 20 ft formats, with both 12- and 16-mil choices across several sizes.
Fit work remains part of the purchase: Many options are rectangular, so buyers with irregular pool outlines should plan for careful measuring and trimming rather than assuming a listed size will match every edge.

More Details on Our Top Picks
VEVOR Solar Pool Cover, 32 x 16 ft, 12 Mil, Blue
The 12-mil polyethylene cover is the lighter-duty choice among these 32 x 16 ft options. It uses a bubble design to help retain heat, limit evaporation, and block leaves and dust, without the added material weight of VEVOR’s 16-mil version. That makes it a practical match for owners who want the core benefits of a solar cover and can handle routine placement and storage. Its cut-to-fit construction also helps when a pool has steps or an irregular outline, though trimming is permanent, so measure carefully first. Compared with the VEVOR 16-Mil Solar Pool Cover, 32 x 16 ft, this model gives up thickness and likely some toughness in exchange for a lighter cover. It still needs rinsing and drying before storage, and it is not a custom-shaped, ready-to-drop-in fit.
Pros:- Bubble design helps retain heat and reduce evaporation.
- Helps block leaves and dust from entering the pool.
- Polyethylene construction is described as resistant to tearing and sun exposure.
- Can be trimmed for pools with nonstandard outlines.
Cons:- The 12-mil construction is thinner than the 16-mil VEVOR options in this roundup.
- A pool that differs from the rectangular dimensions requires careful trimming.
- Needs rinsing and drying before storage.
Best for: Pool owners with a roughly 32 x 16 ft pool who want a lighter 12-mil cover for heat retention and debris control.
Not ideal for: Buyers prioritizing a thicker cover or a precise fit without trimming; the 16-mil VEVOR alternative is better suited to the former.
- Dimensions:32 x 16 ft
- Thickness:12 mil
- Material:Polyethylene (PE)
- Shape:Rectangular
- Color:Blue
- Weight:28.3 lb
- Pool compatibility:Inground and above-ground pools
- Installation:Floating
Our verdict“Choose this lighter 12-mil VEVOR if your pool is near 32 x 16 ft and you value manageable handling over the thicker build of its 16-mil sibling.”
VEVOR 40 x 20 ft Blue Solar Pool Cover, 16 Mil
For a pool with a broad rectangular surface, the standout here is the 40 x 20 ft coverage paired with a 16-mil closed-bubble PE build. The larger sheet can cover more water in one piece than the 32 x 16 ft VEVOR options, helping limit exposed areas where heat and water can escape. Its UV-resistant, waterproof construction is described as resisting tearing, fading, and warping, while the bubble design supports heat retention and debris control. The tradeoff is substantial handling: at 59.1 lb, it is much heavier than the smaller VEVOR covers in this group. It also needs trimming for nonmatching pool shapes, and the listed water guidance—chlorine below 2.5 ppm and pH above 7.2—asks owners to monitor pool chemistry. I’d pick it for coverage, not easy solo handling.
Pros:- Large 40 x 20 ft sheet suits pools with a substantial surface area.
- 16-mil closed-bubble polyethylene supports heat retention and evaporation reduction.
- UV-resistant construction is described as resisting tearing, fading, and warping.
- Can be trimmed to fit a different pool outline.
Cons:- At 59.1 lb, it is notably heavier to place and store than the smaller covers.
- Requires trimming if the pool does not match its rectangular dimensions.
- Specified water guidance calls for chlorine below 2.5 ppm and pH above 7.2.
Best for: Owners of large, rectangular pools close to 40 x 20 ft who want a thicker cover and can manage a heavy sheet.
Not ideal for: Small-pool owners or anyone who needs a light cover that is easy to lift, fold, and store; the smaller 32 x 16 ft VEVOR models are more manageable.
- Size:40 x 20 ft
- Thickness:16 mil
- Material:Polyethylene (PE)
- Design:Closed-bubble
- Color:Blue
- Weight:59.1 lb
- Installation:Floating
- Water guidance:Chlorine below 2.5 ppm; pH above 7.2
Our verdict“Pick this 16-mil model for a large pool that needs broad coverage, but choose a smaller VEVOR cover if handling weight is your priority.”
VINGLI 18 x 36 ft Blue Solar Pool Cover, 12 mil
The VINGLI’s 18 x 36 ft format is the differentiator: it suits a long inground pool better than the 32 x 16 ft VEVOR covers, which would leave a substantially different coverage footprint. Its 12-mil bubble-core polyethylene is designed to absorb solar heat and help keep warmth in the water, while also limiting evaporation and debris. The sheet can be trimmed with scissors for irregular outlines, and the listed welded seams add a construction detail not specified for the VEVOR models here. The compromise is thickness: at 12 mil, it is not the heavier 16-mil choice offered by VEVOR, so buyers focused on a thicker cover may prefer the VEVOR 16-mil 32 x 16 ft model if its size fits. Placement and removal are manual, and the bubble side must face down.
Pros:- 18 x 36 ft dimensions suit a long pool better than the 32 x 16 ft VEVOR models.
- Bubble-core design helps absorb and retain solar heat.
- Can be trimmed with scissors to fit irregular shapes.
- Welded seams are described as part of its heavy-duty construction.
Cons:- At 12 mil, it is thinner than the 16-mil VEVOR covers in this batch.
- Placement and removal are manual.
- The bubble side must face down during use.
Best for: Owners of long, 18 x 36 ft inground pools who need a large cover that can be trimmed around an irregular edge.
Not ideal for: Buyers with above-ground pools or those prioritizing a 16-mil cover; this listing specifies inground use and a 12-mil thickness.
- Dimensions:36 x 18 ft
- Thickness:12 mil
- Material:Polyethylene (PE)
- Shape:Rectangular
- Color:Blue
- Pool type:Inground
- Installation:Manual
- Care:Hand wash only
Our verdict“Choose the VINGLI for a long inground pool that needs 18 x 36 ft coverage, and favor a 16-mil VEVOR instead if thickness matters more than this specific fit.”
VEVOR 16-Mil Solar Pool Cover, 32 x 16 ft, Blue
This VEVOR takes the same 32 x 16 ft footprint as the 12-mil VEVOR but steps up to 16-mil bubble film. That makes it the more suitable choice for buyers who want a thicker sheet for heat retention and everyday pool coverage, while keeping the dimensions manageable compared with the 40 x 20 ft VEVOR. It is specified for both inground and above-ground pools, and its cut-to-fit format can accommodate different outlines. The tradeoff is a heavier sheet: at 37.8 lb, it weighs more than the 12-mil 32 x 16 ft model, which may make frequent removal and storage less convenient. Care is also more particular: use a soft brush and mild detergent, avoid harsh chemicals, and store it in a cool, dry place. It costs buyers flexibility in handling, not coverage.
Pros:- 16-mil bubble film is thicker than the 12-mil VEVOR cover of the same dimensions.
- Suitable for both inground and above-ground pools.
- Helps retain heat, reduce evaporation, and keep leaves and dust out.
- Can be cut to fit different pool shapes.
Cons:- Heavier than the 12-mil VEVOR cover with the same footprint.
- Requires trimming for pools that do not match the rectangular dimensions.
- Care guidance calls for mild cleaning and storage away from harsh conditions.
Best for: Owners of inground or above-ground pools near 32 x 16 ft who want a thicker cover without moving up to the 40 x 20 ft size.
Not ideal for: Those who frequently remove and store their cover alone or who want the lighter 12-mil version; this 16-mil sheet weighs 37.8 lb.
- Dimensions:32 x 16 ft
- Thickness:16 mil
- Material:Polyethylene (PE)
- Shape:Rectangular
- Color:Blue
- Weight:37.8 lb
- Pool compatibility:Inground and above-ground pools
- Installation:Floating
Our verdict“Pick this version over the 12-mil 32 x 16 ft VEVOR when you want a thicker cover and can accept the added weight and care requirements.”
VEVOR 32 x 16 ft, 16 Mil Solar Pool Cover, Blue and Black
This 32 x 16 ft VEVOR shares its 16-mil thickness and footprint with the blue VEVOR 16-mil model, but its blue-and-black dual air-layer design is the distinguishing feature. The stated purpose is to absorb heat during the day and retain warmth at night, making it a better fit for buyers focused on managing temperature across the daily cycle. It is also described as reducing evaporation by up to 95%, though that figure is a product claim rather than a guarantee for every pool. Like the other VEVOR covers, it can be trimmed for an irregular outline and works with inground or above-ground pools. The tradeoff is greater care around water chemistry: the description advises avoiding highly acidic or chlorinated environments, and care is hand-wash only. Compared with the blue-only VEVOR 16-mil cover, its appeal is the layered design, not a different size.
Pros:- Dual air-layer bubble design is intended to support daytime heat absorption and nighttime retention.
- Product data states evaporation reduction of up to 95%.
- Fits inground and above-ground pools and can be trimmed for irregular outlines.
- 16-mil thickness matches the thicker VEVOR option in the same footprint.
Cons:- The description advises avoiding highly acidic or chlorinated environments.
- Hand-wash care may be less convenient than simpler routine cleaning.
- Requires trimming if the pool outline differs from the rectangular dimensions.
Best for: Owners of 32 x 16 ft inground or above-ground pools who value a dual-layer design for daytime heat absorption and nighttime retention.
Not ideal for: Pool owners who cannot maintain the stated chemical precautions or who want a cover with simpler care; hand washing and water-chemistry limits are specified.
- Dimensions:32 x 16 ft (9.75 x 4.88 m)
- Thickness:16 mil
- Material:Polyethylene (PE)
- Color:Blue and black
- Shape:Rectangular
- Weight:37.7 lb
- Pool compatibility:Inground and above-ground pools
- Evaporation reduction:Up to 95%
Our verdict“Choose this model over the blue-only 16-mil VEVOR if its dual-layer design and stated evaporation reduction appeal to you, and you can follow its chemical and care guidance.”
BigXwell Heavy-Duty Solar Pool Cover, 18 x 36 ft, 16 Mil, Blue
The 18 x 36 ft footprint and 16-mil polyethylene make this BigXwell a practical fit for rectangular pools that need broader coverage without moving to a 40-foot length. Like the BigXwell 16 x 32 ft Heavy-Duty Solar Pool Cover, it uses a floating, cut-to-fit design to help capture sunlight, retain warmth, limit evaporation, and keep debris out. The larger size gives it more coverage for longer pools, though buyers with smaller or nonrectangular pools will need to trim it and plan for the leftover material. Its lightweight construction can simplify placement, but it also calls for careful handling: sharp edges and rough storage can damage the cover. Choose this model for its size and 16-mil thickness, not for a ready-made custom fit.
Pros:- 16-mil polyethylene offers a thicker option than the 12-mil VEVOR 28 x 14 ft Solar Pool Cover
- 18 x 36 ft coverage suits longer pools
- Helps capture solar warmth and reduce heat and water loss
- Can be trimmed to fit a different pool outline
Cons:- May require substantial trimming for pools smaller than its listed dimensions
- Needs rinsing, drying, and storage away from sharp objects
- The supplied rectangular shape may not match irregular pool layouts
Best for: Owners of mid-to-large rectangular pools who want 16-mil coverage and are comfortable trimming the cover to fit
Not ideal for: Owners of small pools or buyers who want a precisely fitted cover without cutting and storing excess material
- Dimensions:18 x 36 ft
- Thickness:16 mil
- Material:Polyethylene (PE)
- Shape:Rectangular
- Color:Blue
- Installation:Floating
- Quantity:1
- Care:Rinse off debris, allow to dry, and store away from sharp objects
Our verdict“Choose this BigXwell if your pool needs a generous rectangular cover and you value 16-mil thickness over a ready-cut fit.”
Real Relax 16 mil Solar Pool Cover, 16 x 32 ft Rectangle
The 16 x 32 ft rectangular format makes this Real Relax a clear choice for buyers whose pool already matches a common footprint. Its 16-mil polyethylene cover is meant to absorb solar heat and slow nighttime heat loss, while the stated evaporation reduction of up to 95% addresses water loss as well. The bubble side must face down, so placement takes a little attention; that instruction is more explicit than the supplied setup details for the BigXwell 16 x 32 ft Heavy-Duty Solar Pool Cover. Both can be trimmed, but this Real Relax emphasizes a defined orientation and a specific evaporation claim. Skip it if you want to avoid cutting or if you need a nonrectangular cover straight from the package.
Pros:- 16-mil polyethylene is suited to buyers seeking a thicker cover
- Bubble-side-down installation is specified for heat transfer and nighttime retention
- Designed to reduce evaporation by up to 95%
- Can be cut with scissors to fit a different pool shape
Cons:- Must be placed bubble side down
- The 16 x 32 ft rectangle may need trimming for other pool sizes and shapes
- Cutting is required when the pool does not match the listed dimensions
Best for: Pool owners with a 16 x 32 ft rectangular pool who want a 16-mil cover and can follow the bubble-side-down placement instruction
Not ideal for: Buyers seeking a cover that fits irregular pools without trimming or who do not want to check its orientation during setup
- Dimensions:16 x 32 ft
- Thickness:16 mil
- Material:Polyethylene (PE)
- Shape:Rectangle
- Installation:Floating, bubble side down
- Evaporation reduction:Up to 95%
- Custom fit:Can be trimmed with scissors
Our verdict“Pick the Real Relax for a matching 16 x 32 ft pool if clear placement guidance and a 16-mil build matter more than a no-trim fit.”
BigXwell 16 x 32 ft Heavy-Duty Solar Pool Cover, 16 Mil, Blue
This BigXwell combines a 16 x 32 ft size with 16-mil polyethylene, giving buyers a thicker cover in a footprint shared by the Real Relax 16 mil Solar Pool Cover. Its stated compatibility with both inground and above-ground pools makes it a flexible pick when pool type, rather than just dimensions, is part of the decision. Thermal bubbles help capture warmth, and the cover is designed to reduce evaporation by up to 95%; as with other solar covers, heating depends on sunlight. Compared with the 12-mil VEVOR 28 x 14 ft Solar Pool Cover, this model offers a thicker listed build, but its smaller footprint will not suit wider or longer pools without choosing another size. Trimming helps with unusual outlines, though it cannot add coverage.
Pros:- 16-mil polyethylene is thicker than the 12-mil VEVOR 28 x 14 ft option
- Listed for both inground and above-ground pools
- Thermal bubbles help capture and retain solar heat
- Can be trimmed to fit different pool shapes
Cons:- Heating effectiveness depends on receiving sunlight
- Requires trimming when pool dimensions or shape differ from the rectangle
- The 16 x 32 ft footprint may not cover larger pools
Best for: Owners of inground or above-ground pools near 16 x 32 ft who want a trimmable 16-mil cover
Not ideal for: Owners of pools larger than 16 x 32 ft or pools that receive too little sunlight for solar heating to be useful
- Dimensions:16 x 32 ft
- Thickness:16 mil
- Material:Polyethylene (PE)
- Color:Blue
- Installation:Floating
- Pool compatibility:Inground and above-ground pools
- Evaporation reduction:Up to 95%
- Care:Hand wash with mild detergent and air dry
Our verdict“Choose this BigXwell when you need a 16-mil, cut-to-fit cover for an inground or above-ground pool near its listed size.”
VEVOR Solar Pool Cover, 28 x 14 ft Rectangle, 12 Mil, Blue
At 28 x 14 ft, this VEVOR targets pools that need less coverage than the 40 x 20 ft VEVOR Solar Pool Cover, while retaining a cut-to-fit design for nonstandard outlines. Its 12-mil polyethylene is thinner than the 16-mil BigXwell covers in this lineup, a tradeoff for buyers who prioritize this smaller format over a thicker listed build. The bubble design is intended to absorb heat and limit overnight loss, and the cover also helps reduce evaporation and keep leaves and dust out. VEVOR gives a possible water-temperature increase of 8–15°C, but says conditions affect the result, so I would treat that as dependent on the pool’s environment rather than a guaranteed outcome. The 21.7-pound weight and foldable design make storage a factor to plan for.
Pros:- 28 x 14 ft footprint suits smaller pools than the 40 x 20 ft VEVOR
- Bubble design helps capture daytime heat and reduce overnight heat loss
- Designed to reduce evaporation by up to 95% and block debris
- Foldable and can be cut to fit different pool shapes
Cons:- 12-mil thickness is less than the 16-mil BigXwell models in this lineup
- Temperature gains depend on environmental conditions
- Requires cutting when the pool does not match its rectangular dimensions
Best for: Owners of smaller rectangular pools near 28 x 14 ft who want a foldable cover they can cut to fit
Not ideal for: Buyers seeking a 16-mil cover or a pool cover large enough for a 40 x 20 ft pool
- Dimensions:28 x 14 ft
- Thickness:12 mil
- Material:Polyethylene (PE)
- Shape:Rectangular
- Installation:Floating
- Item weight:21.7 pounds
- Water-temperature increase:8–15°C, depending on environmental conditions
- Evaporation reduction:Up to 95%
- Care:Rinse, dry, then fold or roll
Our verdict“Choose this VEVOR if your pool suits its 28 x 14 ft footprint and a foldable 12-mil cover matters more than a thicker build.”
VEVOR 40 × 20 ft Solar Pool Cover, 12 Mil Blue Rectangle
The defining advantage here is 40 x 20 ft coverage: among these five options, it is the one aimed at large pools that would outgrow the 18 x 36 ft BigXwell. Its 12-mil closed-bubble polyethylene design helps absorb daytime warmth, limit overnight heat loss, reduce evaporation, and keep leaves and dust out. The cover can be cut down and is listed for both inground and above-ground pools, but its 44.3-pound item weight makes handling and storage more demanding than the smaller VEVOR 28 x 14 ft cover. Pool owners also need to follow the listed water conditions—chlorine below 2.5 ppm and pH above 7.2. That combination of large coverage and care requirements makes this a size-led choice, not the simplest option for a small pool.
Pros:- 40 x 20 ft coverage suits pools larger than the 18 x 36 ft BigXwell
- Closed-bubble design helps retain heat and reduce water evaporation
- Can be cut to fit different pool shapes
- Listed for inground and above-ground pools
Cons:- At 44.3 pounds, it is heavier to handle than the VEVOR 28 x 14 ft cover
- Requires trimming for pools that do not match its rectangular footprint
- Listed for chlorine below 2.5 ppm and pH above 7.2
Best for: Owners of large inground or above-ground pools near 40 x 20 ft who can handle and store a larger cover
Not ideal for: Owners of smaller pools who want easy handling, or pool owners whose water conditions do not meet the listed chlorine and pH guidance
- Dimensions:40 x 20 ft
- Thickness:12 mil
- Material:Polyethylene (PE)
- Design:Closed-bubble
- Installation:Floating
- Pool compatibility:Inground and above-ground pools
- Item weight:44.3 pounds
- Water conditions:Chlorine below 2.5 ppm and pH above 7.2
Our verdict“Choose this VEVOR when your pool needs 40 x 20 ft coverage and you can manage its heavier handling and specified water conditions.”
BigXwell 12-Mil Solar Pool Cover, 16 x 32 ft Rectangle
I’d choose this BigXwell when a 16 x 32 ft pool is the priority and a lighter cover is easier to handle than a thicker option. Its 12-mil polyethylene bubble construction is designed to collect solar warmth and slow heat loss, while the manufacturer claims evaporation reduction of up to 95%. That claim is a design target, not a guaranteed result across weather and pool conditions. Compared with the VEVOR 16-mil 24 x 12 ft, this cover is longer and narrower, so it suits a different pool footprint rather than offering the same fit. It can be trimmed for other shapes, but that takes care and removes the option of using the original full dimensions later. I’d also account for rinsing and off-season storage when choosing any floating cover.
Pros:- Thermal bubbles are designed to capture sunlight and retain warmth.
- Manufacturer claims evaporation reduction of up to 95%.
- Can be trimmed with scissors for a custom fit.
- Lightweight construction is intended to make placement and removal easier.
Cons:- The 16 x 32 ft rectangle may need trimming for pools with different dimensions or shapes.
- At 12 mil, it is thinner than the 16-mil options in this roundup.
- Needs cleaning and off-season storage.
Best for: Owners of 16 x 32 ft rectangular pools who want a trim-to-fit solar blanket with a lighter 12-mil build.
Not ideal for: Pool owners seeking a thicker 16-mil cover or a close fit for a 24 x 12 ft pool without trimming.
- Dimensions:16 x 32 ft (384 x 192 in)
- Thickness:12 mil
- Material:Polyethylene (PE)
- Shape:Rectangular
- Color:Blue
- Installation:Floating
- Pool compatibility:Above-ground and in-ground; can be trimmed to fit
- Evaporation reduction:Up to 95%, as described by the manufacturer
Our verdict“Choose this BigXwell if your pool is close to 16 x 32 ft and easy handling matters more than a thicker build.”
VEVOR Blue Solar Pool Cover, 24 x 12 ft Rectangle, 16 mil
This VEVOR pairs a 24 x 12 ft footprint with a 16-mil PE bubble film, making it a useful match for owners who want a thicker listed build without covering a large pool. The bubbles are intended to absorb warmth by day and help limit overnight heat loss; the stated potential temperature increase of 8–15°C depends on conditions, so I wouldn’t treat it as a promise. Compared with the BigXwell 12-mil 16 x 32 ft, this cover is thicker but shorter and wider, changing both the pool fit and handling tradeoff. At 21.3 pounds, it is also a more substantial item to place and remove than a lightweight blanket. Cutting allows customization, though a poor cut can make later adjustments difficult.
Pros:- 16-mil polyethylene is described as tear-resistant and suited to sun exposure.
- Bubble film is designed to absorb daytime heat and retain warmth overnight.

- Can be cut to fit different pool shapes.
Cons:- The 24 x 12 ft rectangle may need trimming for other pool sizes.
- At 21.3 pounds, it is heavier than a lightweight cover.
- Heating results vary with environmental conditions.
Best for: Owners of pools near 24 x 12 ft who prefer a 16-mil cover and can manage a heavier blanket.
Not ideal for: Buyers with larger pools or anyone expecting a fixed temperature increase regardless of sun, weather, and water conditions.
- Dimensions:24 x 12 ft
- Thickness:16 mil
- Material:Polyethylene (PE)
- Shape:Rectangular
- Color:Blue
- Installation:Floating
- Weight:21.3 pounds
- Features:Tear-resistant; can be cut to fit
Our verdict“Pick this VEVOR for a smaller pool when its 24 x 12 ft footprint and thicker 16-mil construction suit your needs.”
BigXwell Heavy-Duty Solar Pool Cover, 20 x 40 ft, 16 Mil, Blue
For a large pool with a matching footprint, this BigXwell offers 20 x 40 ft coverage and a 16-mil thickness, giving it a different job from the smaller VEVOR blankets in this group. Its polyethylene bubble cover is designed to absorb solar warmth, reduce water and chemical evaporation, and block leaves and dust while it floats. That broad coverage is useful only if the pool dimensions align: trimming a large blanket is possible in principle, but inaccurate cutting can waste material and complicate fitting. Compared with the VEVOR 16-mil 24 x 12 ft, this is the better scale for a much larger rectangular pool, not a more convenient choice for small pools. It is described as lightweight for its size, but still needs cleaning, drying, and storage.
Pros:- Large 20 x 40 ft size suits a correspondingly large rectangular pool.
- 16-mil PE construction is designed to help retain heat.
- Helps reduce water and chemical evaporation while shielding against debris.
- Designed for straightforward installation and removal.
Cons:- The listed dimensions are a poor match for pools substantially smaller than 20 x 40 ft.
- Cleaning and drying are needed before storage.
- The large sheet may take more room to handle and store than smaller options.
Best for: Owners of large 20 x 40 ft rectangular pools who want a 16-mil floating cover for heat and evaporation management.
Not ideal for: Owners of small or irregularly shaped pools who would need extensive trimming to use the large rectangle.
- Dimensions:20 x 40 ft
- Thickness:16 mil
- Material:Polyethylene (PE)
- Shape:Rectangular
- Color:Blue
- Installation:Floating
- Additional feature:Thermal insulation
- Care:Clean with water and mild soap, dry, then fold or roll for storage
Our verdict“Choose this BigXwell when you need broad 20 x 40 ft coverage and have space to handle and store a large blanket.”
VEVOR Blue Solar Pool Cover, 24 x 12 ft, 12 Mil
This VEVOR is the 12-mil alternative to the brand’s 16-mil 24 x 12 ft cover, so the choice is mainly between a thinner listed build and the thicker model’s more substantial material. Its bubble-film PE design is meant to capture daytime warmth, slow heat loss, limit evaporation, and keep leaves and dust out. It can also be trimmed for other shapes, though I’d measure carefully before cutting. Compared with the BigXwell 12-mil 16 x 32 ft, this VEVOR has the same stated thickness but a shorter, wider footprint; the right pick depends on pool dimensions, not a presumed performance gap. It suits owners who want a basic floating cover in this size, but it still needs rinsing, drying, and protected storage when unused.
Pros:- Bubble design is intended to absorb heat and reduce heat loss.
- Helps limit evaporation and keep leaves and dust out of the pool.
- Can be trimmed for different pool shapes.
- PE material is described as resistant to tearing and sun exposure.
Cons:- The 24 x 12 ft rectangle may require trimming for other pool dimensions.
- Thinner at 12 mil than the matching-size VEVOR 16-mil model.
- Requires cleaning, drying, and storage away from direct sunlight.
Best for: Owners of pools near 24 x 12 ft who want a 12-mil floating cover that can be trimmed for fit.
Not ideal for: Buyers prioritizing a thicker listed material build, who may prefer the matching-size VEVOR 16-mil version.
- Dimensions:24 x 12 ft
- Thickness:12 mil
- Material:Polyethylene (PE)
- Shape:Rectangular
- Color:Blue
- Pool compatibility:In-ground and above-ground pools
- Design:Bubble film; cut-to-fit
- Care:Clean with warm water and mild soap, air dry, and store in a cool, dry place away from direct sunlight
Our verdict“Pick this version if your pool fits the 24 x 12 ft format and you prefer the 12-mil build over VEVOR’s thicker same-size alternative.”
VEVOR 28 x 14 ft Blue Solar Pool Cover, 16 Mil
With a 28 x 14 ft footprint and 16-mil PE construction, this VEVOR fills the gap between the compact 24 x 12 ft covers and the much larger BigXwell 20 x 40 ft sheet. Its bubbles are designed to collect warmth during the day, slow overnight heat loss, and reduce evaporation while keeping some debris out of the water. The larger format may suit a mid-size pool with extra margin for trimming, but it also creates more material to position and store; its listed weight is 29 pounds. Compared with the VEVOR 24 x 12 ft, 16-mil cover, this one offers more coverage in the same thickness, which helps only if your pool dimensions call for it. Measure first, since cutting is difficult to reverse.
Pros:- 28 x 14 ft size offers more coverage than the 24 x 12 ft VEVOR options.
- 16-mil polyethylene bubble design is intended to retain warmth and limit evaporation.
- Can be trimmed for different pool shapes.
- Suitable for above-ground and in-ground pools.
Cons:- The rectangular sheet may need careful trimming for nonstandard pools.
- Listed weight of 29 pounds may make frequent placement and removal more demanding.
- Requires regular cleaning and proper storage when not in use.
Best for: Owners of mid-size above-ground or in-ground pools who need more coverage than a 24 x 12 ft blanket and want 16-mil material.
Not ideal for: Owners of small pools who would have to remove substantial material, or buyers who need a lighter blanket to handle frequently.
- Dimensions:28 x 14 ft
- Thickness:16 mil
- Material:Polyethylene (PE)
- Shape:Rectangular
- Color:Blue
- Installation:Floating
- Weight:29 pounds
- Pool compatibility:In-ground and above-ground pools
- Features:Bubble design, foldable, cut-to-fit
Our verdict“Choose this VEVOR if a 24 x 12 ft cover is too small but the 20 x 40 ft BigXwell is far more coverage than your pool needs.”
How We Picked
I ranked these solar pool covers by the buyer decisions the product details can support: listed dimensions, material thickness, range of available sizes, and how easily a shopper can identify a plausible fit. I gave extra weight to options that pair a commonly sought rectangular size with a 16-mil build, while also including thinner covers for buyers who prioritize a lighter, more manageable sheet. The lineup’s size range matters because a cover that does not fit the pool is a poor choice regardless of thickness.
The ranking reflects fit flexibility and clear use cases, not claims of measured heating performance or durability testing. I treated each product’s stated size and thickness as the available evidence; details such as warranty, exact material composition, and included accessories were not provided here and should be checked on the current product listing. Similar-size options are ranked by how clearly they serve a distinct need, while larger and smaller formats are placed for shoppers whose pool dimensions call for them. Every pick has a tradeoff: thickness may add handling effort, and a wider size selection does not remove the need to measure and trim accurately.

Factors to Consider When Choosing Solar Pool Covers
Choosing among these covers starts with the pool, not the product name. I would confirm the waterline dimensions, decide how often the cover will be handled, and then compare thickness and shape against those needs. The following factors help avoid buying a cover that is awkward to use or difficult to fit.
Measure the pool surface, not just the outside frame
Measure the water surface at its widest points and note whether the pool is truly rectangular. Coping, steps, ladders, and rounded corners can make the usable shape differ from the nominal pool dimensions. A cover can usually be cut to fit, but starting with a sheet that is too small leaves no room to correct measurement errors. A larger sheet provides trimming flexibility, yet it can take more effort to position and may create extra material to store. Measure twice before choosing between close sizes such as 28 x 14 ft and 32 x 16 ft.
Choose thickness with handling habits in mind
The products here are listed at either 12 or 16 mil, making thickness a useful comparison point, but it does not settle every question about performance or lifespan. A thicker cover may suit someone seeking a more substantial sheet, while a thinner one may be easier to move and fold for routine access. Actual handling also depends on the cover’s full dimensions, so a large 12-mil cover can still be cumbersome. Think about who will remove it and how often before selecting a thicker option. Avoid treating the mil number alone as a guarantee of heating results or years of service.
Match the shape and size to obstacles around the pool
Most options in this roundup are rectangular, which makes them a natural match for straight-sided pools. For freeform pools, built-in steps, or unusual corners, expect to trim the sheet and check how the cut edges will sit around obstacles. Do not size only to the longest and widest measurements if that leaves excess material catching on a ladder or deck feature. A paper sketch with measurements for each section can help you plan cuts before opening the cover. If a pool has a complex outline, prioritize a size with enough extra coverage to allow careful fitting.
Think through removal, storage, and daily access
A cover only helps while it is on the pool, so the removal routine matters as much as the dimensions. Large sheets, particularly formats around 18 x 36 ft or 20 x 40 ft, may be awkward for one person to fold and store. If you swim often, consider how you will roll or lift the cover and where it will go between uses; a reel may make daily handling easier, but compatibility and included accessories should be verified separately. Buyers who cover the pool less often may tolerate a more cumbersome sheet in exchange for the size or thickness they need. Plan the storage space before ordering rather than after the cover arrives.
Set expectations for heat retention and evaporation
A solar cover can help limit heat loss and water evaporation, but results depend on weather, pool temperature, wind exposure, and how consistently the pool is covered. It is not a replacement for a heater when precise temperature control is the goal. A cover that fits closely and is used regularly may be more useful than a thicker sheet that stays folded beside the pool. If evaporation control is your main reason for buying, pay close attention to full-surface coverage and gaps around the edges. Compare product claims against your climate and routine rather than expecting one thickness to perform identically in every setting.
Check care, warranty, and product details before ordering
Dimensions and mil ratings do not tell the whole story, so check the current listing for material details, care instructions, warranty terms, and whether a reel or storage accessory is included. Sun exposure, chemical balance, and storage conditions can affect a cover’s service life, making proper care part of the ownership tradeoff. Follow the maker’s guidance on removing the cover during chemical treatments or other conditions that could affect the material. Do not assume that two covers with the same size and thickness use identical construction. When the listing leaves a detail unclear, verify it before making the final choice.
Frequently Asked Questions
Should I choose a 12-mil or 16-mil solar pool cover?
Choose based on how you balance a more substantial sheet against routine handling, not on thickness alone. This roundup has both options in several VEVOR sizes and at 16 x 32 ft from BigXwell, which makes those formats useful for comparing the stated thickness at similar dimensions. A 16-mil cover may appeal if a thicker build is your priority, while a 12-mil option may suit buyers who want a thinner sheet. The full cover size also affects how difficult it is to lift and store. Check the product’s construction and care information, since mil rating by itself does not establish a guaranteed lifespan or heating result.
How much larger should a solar pool cover be than my pool?
There is no single extra margin that fits every pool because the outline, corners, and obstacles vary. Measure the water surface and compare it with the cover’s stated dimensions, leaving enough material for careful trimming if the sheet is larger. A cover that is too small cannot be stretched to cover missing areas, while excessive overhang can snag or make handling harder. For pools with steps or curved edges, sketch the outline and plan the cuts before trimming. Keep in mind that cutting is generally a one-way adjustment, so take measurements carefully.
Which size in this roundup fits a 16 x 32 ft rectangular pool?
The lineup includes multiple 16 x 32 ft options: Real Relax at 16 mil, BigXwell at 16 mil, BigXwell at 12 mil, and VEVOR at 16 mil. Compare those direct-size choices first rather than buying a larger sheet by default. Confirm whether your measurements describe the water surface or the pool’s outside dimensions, and check how the cover is intended to sit at the edges. If your pool has steps or an irregular end, a larger format may give you trimming room, though it adds handling and storage bulk. Check each listing for its exact stated dimensions before ordering.
Is a solar pool cover useful if I already have a pool heater?
A cover can complement a heater by reducing heat loss and evaporation when the pool is not in use, but it does not replace temperature control from the heater. Whether it makes sense depends on how often the pool is uncovered and the local weather. A cover that is difficult to remove may get used less, so handling and storage can affect its practical value. Follow both the heater and cover manufacturers’ instructions, especially around chemical treatments and operating conditions. Compare the expected routine benefits with the effort of putting the cover on and taking it off.
Do I need a reel for a large solar pool cover?
A reel is not automatically required, but it can make repeated removal and replacement easier, particularly for broad sheets such as 18 x 36 ft or 20 x 40 ft. Whether a reel works depends on the cover’s dimensions, the pool layout, and the reel’s compatibility; do not assume one is included with these products. For occasional use, two people may be able to manage a large cover without a reel, while frequent swimmers may benefit from a more organized removal setup. Check where the rolled cover will sit and whether the reel can clear nearby steps or deck features. Factor in the extra equipment and space when choosing a large format.
Conclusion
For a balanced choice among the listed dimensions and thicknesses, I recommend the BigXwell Heavy-Duty 18 x 36 ft, 16-mil cover as best overall, especially for a larger rectangular pool that matches its footprint. My best value-style pick is the BigXwell 16 x 32 ft, 12-mil cover for shoppers who want a direct-fit size and a thinner build; verify the current listing details before deciding. For a premium-leaning option, consider the BigXwell 20 x 40 ft, 16-mil cover if your pool genuinely needs that large format and you can manage its handling. A beginner with a common 16 x 32 ft pool can start by comparing the VEVOR, Real Relax, and BigXwell options at that size, then choose based on thickness and product details. For smaller rectangular pools, look at the 24 x 12 ft VEVOR covers; for a 40 x 20 ft pool, compare the VEVOR 12- and 16-mil versions. The right choice is the one that fits your water surface, suits your removal routine, and matches the tradeoff you prefer between thickness and manageability.
