Shopping for a solar cover for an inground pool usually starts with one stubborn problem, too much heat slipping away overnight. The right cover can help hold warmth, cut evaporation, and keep leaves from turning a clean pool into extra work. This roundup focuses on sizes, material thickness, and whether a cover makes sense for day-to-day pool care, winter storage, or a mixed backyard setup.

More Details On Our Top Picks
Larger rectangular pools tend to expose every weak spot in a cover, and this 18 by 36 size is aimed at that kind of job. The 12 mil build gives you a middle-ground feel, thicker than thin economy blankets without turning the roll-up routine into a chore. For a family that uses the pool often, that balance matters.
Compared with the 16 by 32 option below, this one is the steadier match for wider water surfaces and longer lap-style pools. The blue finish keeps the look straightforward, and the cover format fits the usual solar-blanket style many owners already know how to handle.
Strong Points
- 18 by 36 sizing suits larger rectangular pools.
- 12 mil thickness lands in a sensible middle zone.
- The blanket style is familiar for seasonal use.
- Blue coloring keeps the look simple and classic.
- Useful for holding warmth between swim sessions.
Things To Consider
- That larger footprint can feel bulky during removal and storage.
- You still need a separate way to trim or roll it neatly.
- Pool shape matters, a tight fit is easier to manage than extra overhang.
Key Specs
Who It Suits Best
You get the most from this one in a larger rectangular inground pool where coverage matters more than compact storage.
Where A Sibling Pick Shines
In The Swim 16′ x 32′ Premium Blue Rectangle Solar Pool Cover 12 Mil suits smaller standard rectangles better, especially for owners who want a little less material to handle.
This 16 by 32 format sits in the sweet spot for a lot of rectangular inground pools, especially the common backyard setup that doesn’t need oversized coverage. The 12 mil build keeps it in the same family as the larger In The Swim option, but with less material to wrestle during placement and storage. That usually makes daily handling feel easier.
For a homeowner who wants a straightforward solar blanket without a lot of extras, the fit is easy to understand. The trade-off is simple, you get a lighter handling load than the larger version, but you also give up the wider span that bigger pools need.
What We Like
- Standard 16 by 32 sizing fits many rectangular pools.
- 12 mil thickness keeps the blanket in a usable middle range.
- Less awkward to move than larger rectangular covers.
- Good match for routine warm-weather use.
Worth Noting
- Storage still takes planning, especially after a long season.
- Owners with larger pool dimensions may need a bigger match.
- Like most solar blankets, edge care affects how neatly it stays usable.

Made For
You suit this pick best when your pool is a standard rectangle and you want a cover that feels manageable through the season.
Another Choice May Suit
In The Swim 18′ x 36′ Premium Blue Rectangle Solar Pool Cover 12 Mil is the better fit for larger water surfaces that need broader coverage.
Some pool owners want a simple solar blanket that stays focused on the basics, and this VINGLI cover does exactly that. The 12 mil PE build, meaning polyethylene, gives you a familiar pool-blanket material with a design meant to hold heat and cut water loss. In a backyard that sees frequent afternoon swims, that can be the difference between a comfortable pool and one that cools off too quickly.
Compared with the two In The Swim picks, this one leans more into straightforward value than brand familiarity. The listed trim-friendly format is useful too, because a custom-ish fit can matter when your pool measurements leave only a little wiggle room.
Positives
- 12 mil PE construction keeps the feel familiar and practical.
- The bubble-core design is aimed at heat retention.
- Useful for reducing routine top-off water needs.
- Trim-and-fit flexibility helps with awkward pool dimensions.
- Good fit for owners who want the basics done well.
Softer Spots
- Trim work adds a little extra setup time.
- Like most solar blankets, storage takes some care after use.
- The simple format leaves less room for specialty features.

Right Fit For

A Better Fit Elsewhere
Sun2Solar Solar Pool Cover 16 Mil 18 x 36 Ft Blue Solar Blanket is a smarter step up for a larger pool that needs broader coverage and a thicker feel.
For pool owners who care about a sturdier-feeling blanket, this 12 mil option lands in familiar territory without looking flimsy. It is built for both inground and above-ground use, which makes the listing more flexible than the narrower pool-specific options above. The fact that it is described as made in the USA may matter to shoppers who like that kind of sourcing detail, even though the real draw is still the straightforward 16 by 32 format.
That extra build focus makes it a sensible choice for routine seasonal use, especially in a yard where the cover gets moved on and off often. The trade-off is obvious, a heavier-feeling cover can take more space and patience to manage than a lighter blanket.
Highlights
- Heavy-duty positioning suits regular seasonal handling.
- 16 by 32 size fits a lot of standard rectangles.
- Works for both inground and above-ground setups.
- Made in the USA may matter to some shoppers.
Small Caveats
- Sturdier construction usually means more bulk in storage.
- Pool fit still depends on your exact dimensions.
- Handling is less convenient than with smaller blankets.

Best Suited To
You suit this pick best when you want a sturdy 16 by 32 solar blanket and you use the pool enough to notice handling quality.
Look Elsewhere When
In The Swim 16′ x 32′ Premium Blue Rectangle Solar Pool Cover 12 Mil is easier to size-match for a pure backyard solar blanket focus.
This is a different lane from the solar blankets above, because a safety cover is about seasonal closure rather than heat gain. The green mesh style helps shed water while still covering the pool surface, which can suit owners who shut things down for colder months and want less mess to clear later. For a standard 14 by 26 rectangle, the fit is the main story.
Compared with VINGLI and the In The Swim blankets, this option is for winter storage and closure more than warm-weather swimming. Mesh covers tend to feel less like a daily-use accessory and more like a seasonal system piece, which is why the right pool dimensions matter so much.
Reasons To Buy
- Mesh safety format suits winter pool closure.
- 14 by 26 sizing targets a clear pool shape.
- Useful for owners who prefer seasonal protection over solar heating.
- The green mesh look is straightforward and discreet.
Areas To Watch
- Mesh safety covers are a different use case from solar blankets.
- Installation usually takes more planning than a simple throw-on cover.
- Cleaning and storage still need care between seasons.

Whose Shelf It Belongs On
You suit this pick best when your pool closes for the cold season and you want a mesh safety cover sized for a 14 by 26 rectangle.
Skip It When
Sun2Solar Solar Pool Cover 16 Mil 18 x 36 Ft Blue Solar Blanket is the better match for a swimming season solar setup rather than a closure-only cover.
That center-end step changes the story here, because not every large inground pool has a clean rectangle with no cutout. This VEVOR cover is aimed at bigger layouts that need a 20 by 40 footprint plus a 4 by 8 step section, which makes it more specialized than the 14 by 26 VEVOR model. The triple-stitched construction and abrasion-resistant note point toward harder seasonal use.
You feel the benefit most in a pool with a more complex shape, where a standard rectangle leaves awkward uncovered areas. The trade-off is setup complexity, since a cover built for a step area usually asks for more planning and more careful installation.
Bright Spots
- 20 by 40 size covers a large pool footprint.
- 4 by 8 center-end step section adds shape-specific coverage.
- Triple stitching suggests a stronger seam approach.
- Abrasion-resistant design suits seasonal handling.
Minor Gripes
- Step cutouts make installation more involved.
- The larger layout will take more storage space.
- It is aimed at specific pool shapes, not every rectangle.
Core Details
Built With In Mind
You suit this pick best when your inground pool has a center-end step and a larger rectangle that needs a shape-matched safety cover.
Swap It Out When
VEVOR Pool Safety Cover Fits 14x26ft Rectangle Inground Safety Pool Cover is the simpler fit for a smaller rectangle without the step section.
The jump from 12 mil to 16 mil matters because thickness changes the feel of the blanket and usually points to a heavier-duty build. In this Real Relax cover, that thicker profile pairs with a 16 by 32 rectangle, so it stays in the practical backyard size range while aiming for a sturdier hand. For owners who leave a cover on for longer stretches, that combination can be attractive.
It sits above the lighter 12 mil options from In The Swim and VINGLI when you want more material under your hands. The honest trade-off is that a thicker cover can be less easy to move, especially on windy pool decks or when you store it after repeated use.
Positives
- 16 mil thickness signals a heavier-duty blanket.
- 16 by 32 sizing fits common rectangular pools.
- Works for both inground and above-ground use.
- Blue bubble style is familiar and easy to understand.
- Good match for owners who keep the cover on often.
Points To Note
- Heavier material can be more awkward to fold and store.
- Pool fit still depends on exact dimensions.
- Like other bubble blankets, careful handling helps it stay neat.

The Right Fit
You suit this pick best when you want a thicker solar blanket for a standard rectangle and don’t mind a little more handling weight.
Where Another Pick Suits Better
In The Swim 16′ x 32′ Premium Blue Rectangle Solar Pool Cover 12 Mil is the easier day-to-day pick for a lighter, simpler blanket.
The smaller 12 by 24 size makes this an easier cover to handle in a compact rectangular pool. At 10 mil, it sits lighter than the 12 mil and 16 mil options above, which can be welcome for an owner who values easier lifting over a heavier blanket feel. That lighter profile can matter a lot when the cover comes on and off often.
Compared with the broader In The Swim and Sun2Solar options, this one is about keeping the setup modest and manageable. The compromise is also clear, you give up some heft, so it fits best where the pool is smaller and the handling ease matters more than a thicker cover.
What We Like
- 12 by 24 sizing suits smaller rectangle pools.
- 10 mil thickness keeps handling lighter.
- Bubble blanket format is easy to understand.
- Good for owners who want a simpler daily lift.
Room For Improvement
- Lighter thickness usually means less substantial feel.
- Smaller coverage makes it a niche fit.
- Frequent folding still calls for neat storage habits.

Reach For A Different Pick
Sun2Solar Solar Pool Cover 16 Mil 18 x 36 Ft Blue Solar Blanket is the better fit for a larger pool and a thicker blanket feel.
Sun2Solar goes after the homeowner who wants a thicker solar blanket for a larger rectangular pool and values broader coverage. The 16 mil construction gives it a heftier feel than the 12 mil picks, and the 18 by 36 size lines up with bigger backyard layouts. In practice, that makes it a strong fit for owners who want to hold heat longer and limit daily cleanup.
Compared with the Real Relax 16 mil option, this one leans more clearly into the Sun2Solar pool-blanket identity, with the product description pointing to water conservation and debris control. That balance of heat retention and surface protection is useful in a pool that sees trees, wind, or a lot of sunny-hour use.
Upsides
- 16 mil thickness gives the blanket a substantial feel.
- 18 by 36 size suits larger rectangular pools.
- Helpful for keeping out leaves and other surface debris.
- Water conservation focus fits routine backyard pool care.
- Good choice for owners who want a fuller-featured solar blanket.
Honest Caveats
- The larger size takes more room to fold and store.
- Heavier blankets can be less convenient for solo handling.
- Pool fit is still the deciding factor, especially with long rectangles.

How To Choose The Right Solar Cover For Inground Pool
Start With Fit, Not Hype
Pool size comes first because a solar blanket only works well when it covers the water cleanly. A 16 by 32 rectangle suits many standard inground pools, while 18 by 36 or 20 by 40 layouts are better for larger basins and special step sections. An undersized cover leaves water exposed, and an oversized one becomes harder to manage.
Shape matters too. Rectangle covers suit straight-sided pools best, while a safety cover with a step cutout belongs on a pool that actually has that shape. Pool owners with freeform edges usually need a more careful measurement pass before choosing any blanket.
Choose Thickness By Handling Style
Mil rating means thickness, and it gives you a rough clue about how the blanket will feel in daily use. A 10 mil cover is usually lighter to move, 12 mil sits in the middle, and 16 mil points to a heavier build that many owners prefer for a more substantial feel. The trade-off shows up at storage time, because thicker covers usually take more effort to fold and store.
For a backyard that sees frequent use, a middleweight blanket often feels easier to live with. For a pool that stays covered longer, the heavier option can make sense even though it asks more from your arms and storage space.
Match The Cover To The Season
Solar blankets and safety covers solve different problems. A solar blanket helps hold warmth and reduce evaporation during swim season, while a mesh safety cover is built for colder months and pool closure. Mixing those goals usually leads to frustration, so the use case should stay clear from the start.
That choice also changes maintenance. Solar blankets need care when you dry, roll, and store them, while safety covers ask for a more deliberate seasonal install. A simple rule helps here, swimming season points to solar, shutdown season points to safety.
Think About Your Routine
Daily handling matters more than most product pages admit. A cover that gets removed often should feel manageable, especially for one person, and a larger blanket can become awkward on windy days or narrow pool decks. Storage space matters too, because folded pool covers can take more room than expected.
Owners who clean around trees or nearby landscaping also benefit from a cover that is easy to lift and replace. The right choice is the one that fits your pool and your routine, not just the biggest number in the title.
Things Worth Knowing First
Hidden Buying Traps
One common slip is treating all pool covers as the same thing. A solar blanket and a safety cover solve different jobs, so choosing the wrong style leaves you with a cover that doesn’t match the season. Another easy miss is guessing on pool dimensions instead of measuring edge to edge.
Thickness can trip people up too. A thicker blanket feels sturdier, but it also weighs more and takes more space, so a casual weekend swimmer may prefer a lighter 10 or 12 mil option instead of jumping straight to 16 mil.
The Upgrade Payoff
Higher-tier covers usually cost more because the material is heavier, the coverage is broader, or the shape is more specialized. Step cutouts, triple stitching, and thicker builds all add material and construction complexity. That extra cost starts to make sense when your pool has an unusual shape or you want a cover that stays in service longer.
For a standard rectangular pool used a few times a week, a simple 12 mil blanket often makes better sense than paying for specialized construction. For a large pool or a setup that stays covered for long stretches, the sturdier option can feel worth it.
Frequently Asked Questions
What size solar cover fits an inground pool best?
The best fit matches your pool’s exact rectangle, not just the nearest common size. A 16 by 32 cover suits many standard layouts, while larger pools usually need 18 by 36 or 20 by 40 coverage.
What does mil thickness mean?
Mil is a thickness measure for the cover material. Lower numbers usually feel lighter, while higher numbers usually feel more substantial in hand.
Should you choose a solar blanket or a safety cover?
Choose a solar blanket for swimming-season heat retention and evaporation control. Choose a safety cover for seasonal shutdown and winter closure.
Are thicker covers always better?
Thicker covers can feel sturdier and more substantial, which helps for heavier use. They also take more effort to handle and store.
Can one cover work for both inground and above-ground pools?
Some listings do cover both pool types, but the size still has to match the water area. Pool shape and exact dimensions matter more than the pool type label alone.
Closing Thoughts
The right solar cover for your inground pool comes down to fit, thickness, and how you actually use the water. Larger rectangles need broader coverage, while smaller pools are easier to live with using a lighter blanket. Safety covers belong to seasonal shutdown, not warm-weather swimming. Once you match the cover to your routine, the choice gets a lot simpler, and the pool feels easier to care for through the season.
