Closing a backyard pool for winter used to mean wrestling a tarp into submission. Modern roll out pool covers lay down taut over the surface, anchor to brass or steel points around the deck, and keep leaves, snow, and curious critters out until spring. The right one depends on pool size, whether you have a center step, and how much shade you want the cover to throw.
The list below mixes safety-rated mesh covers (built to support weight and drain rain) with one solar bubble blanket for warmer climates or off-season heat retention. Each pick works for a specific pool footprint, so measuring your rectangle before you order is the single biggest step to getting this right.

A Closer Look At Each Pick
The CIDNN 16×32 in blue targets the most common residential inground rectangle, so it suits a wide swath of suburban backyards without forcing a custom quote. The mesh weave sheds rainwater through the fabric instead of pooling on top, which lightens the load on the anchors during a wet winter.
Installation arrives in one box with brass anchors, steel springs, and the wrenches needed to tension the cover. For most homeowners with a basic drill and a helper, the first setup takes a few hours rather than a full weekend.
Everyday Perks
- Sized to the most popular 16×32 inground footprint, removing guesswork from the order
- Mesh design allows rainwater to drain through, so no standing puddles after a storm
- Includes a safety net, brass anchors, and steel springs in the box for first-time setup
- Tension-spring system pulls the fabric taut, which helps it stay flush in windy conditions
Things To Consider
- Some fine silt and pollen can pass through the mesh weave, so a spring cleanup may still be needed
- Anchors require drilling into the deck, which is a permanent commitment to cover placement
Feature Snapshot
Who It Suits Best
Homeowners with a standard 16×32 inground rectangle who want a complete anchor kit in one shipment.
Look Elsewhere When
Your pool has a center step section, in which case the CIDNN 16×32 with 4x8ft center step (the green variant) is a better shape match.
Stepping up to an 18×36, the blue CIDNN mesh keeps the same hardware package as the smaller sibling but stretches over a noticeably larger rectangle. Pools this size often belong to families who actually swim laps, so the cover’s ability to keep the water clean all winter pays off when May rolls around.
Because the surface area is bigger, expect a longer spread-and-tension process during installation. Two helpers make the layout phase much easier, and a second person on the springs keeps the fabric even on both sides.
Noteworthy Benefits
- Covers the 18×36 inground rectangle without resorting to a custom order
- Mesh fabric sheds rainwater and reduces the weight load on anchor points
- Complete hardware kit means no extra trips for anchors or tension springs
- Blue tone blends with many pool deck color schemes
Trade Offs
- Larger surface area means more careful layout to avoid wrinkles catching wind
- Mesh weave allows some fine debris through, so a quick vacuum at opening is common
Right Fit For
Owners of mid-to-large 18×36 inground pools who want a stocked kit and a familiar blue color.
Consider Something Else When
Your pool has a center step, in which case the CIDNN 18×36 with 4x8ft step section is the better shape match.
Center steps break the simple rectangle pattern, and a cover that ignores the step leaves a wide gap for leaves and critters. The CIDNN 18×36 with a 4x8ft center step extension covers both the main basin and the step cutout as one continuous piece, which is a real upgrade from a flat rectangle lashed over a step.
For pools shaped this way, the step cutout is also where small children and pets are most likely to wander onto the water, so a properly fitted cover is a safety investment as much as a cleanliness one.
Where It Delivers
- Integrated 4x8ft step section eliminates the most common gap on stepped pools
- Mesh weave keeps rainwater from pooling on the cover surface
- Complete hardware kit with brass anchors and steel springs for full installation
- Green tone fades naturally into landscaped backyards
Room For Improvement
- Custom-shaped cover takes longer to align correctly than a plain rectangle
- Step section requires careful anchor placement around the curve to maintain tension
Key Product Details
Made For
Homeowners with an 18×36 inground pool featuring a center step section who want one continuous cover rather than a workaround.
Skip It When
Your pool is a plain rectangle with no step, in which case the standard CIDNN 18×36 mesh is the simpler and less expensive choice.
The green 16×32 is the color-shifted sibling of the blue version reviewed earlier, and it exists for backyards where green hides better than blue against grass, stone, or surrounding landscaping. Functionally, the mesh, hardware, and installation process match the blue version exactly.
For shoppers who already know they want a 16×32 rectangle and just need to choose a color that matches the deck palette, this narrows the decision to a simple aesthetic call.
What Helps Most
- Matches the popular 16×32 rectangle without custom sizing
- Green color blends with grass and natural stone surroundings
- Mesh fabric drains rainwater and reduces standing water
- Full hardware kit included for a one-box installation
Honest Caveats
- Same mesh weave means fine debris can still pass through into the water
- Color choice does not change durability, so it really is a visual decision
Best Suited To
Pool owners with a 16×32 rectangle who prefer green over blue for visual harmony with the yard.
Not Your Match When
You need a center step cover, in which case the CIDNN 16×32 with 4x8ft step section is the right shape match.
For smaller pools with a step, this 16×32 with a 4x8ft step extension covers the common residential setup without forcing a step cutout that is too large for the basin. The green tone stays consistent with the rest of the mesh line, so the cover looks intentional rather than oversized.
Compared to the larger 18×36 step version reviewed earlier, this one is easier to handle during installation because the total fabric footprint is more compact. Solo installers with a careful approach can usually manage it without recruiting a second helper.
Well-Handled Touches
- Step section integrates with the main 16×32 cover as a single piece
- Green color fades naturally into surrounding landscaping
- Mesh construction drains rainwater through the fabric
- Complete hardware kit included for full installation
Small Caveats
- Step cutout still requires careful measurement to align with the actual step shape
- Mesh allows fine silt to pass through, so a spring vacuum is the norm
Spec Overview
Who Should Grab It
Homeowners with a 16×32 inground pool and a center step who want a fitted, single-piece cover in green.
A Better Fit Elsewhere
Your pool runs longer at 18×36, in which case the CIDNN 18×36 step version covers the larger basin properly.
The 99% shading rate on this tan CIDNN cover sets it apart from standard mesh. Sunlight is the engine of algae growth, so blocking nearly all of it over the off-season keeps the water clearer and reduces the chemistry shock waiting for you in spring.
The trade-off is that tighter weaves hold more rainwater on top, so the cover works best where the included pump can keep up with seasonal precipitation. For most backyards, a quick pump-out every few weeks handles it without drama.
What Earns Its Place
- 99% shading blocks nearly all sunlight, slowing algae growth under the cover
- High-strength polypropylene build supports weight and resists tearing
- Tan color hides dirt and pollen between seasonal cleanings
- Complete installation kit included for first-time setup
Points To Note
- Denser weave holds more rainwater, so a cover pump is a practical add-on
- Higher shading means slightly more weight per square foot when wet

Whose Shelf It Belongs On
Pool owners in treed lots with heavy leaf fall who want maximum light blocking and minimal spring cleanup.
Swap It Out When
You prefer a lighter mesh that drains freely, in which case the standard CIDNN 16×32 blue or green mesh is the better fit.
At 16×40, this cover is built for the long rectangle, the lap pool layout that some homeowners install for serious swimming. The narrow width keeps it from looking oversized on a long basin, while the extra length covers the full swim corridor without a seam.
Because the fabric is long, installation is a two-person job at minimum, and three makes it easier. Plan a calm morning for the layout phase so the wind does not win the spread.
The Upside
- Specifically sized for 16×40 long rectangles without custom cutting
- Mesh weave drains rainwater, lightening the load on the anchor system
- Green color blends with grass and landscaping along the pool edge
- Complete hardware kit arrives with the cover
Worth Bearing In Mind
- Long fabric takes more hands to spread evenly during installation
- Mesh weave allows fine debris to pass through to the water below
Perfect Match For
Owners of 16×40 lap-style rectangles who want a fitted safety cover in one piece.
Reach For A Different Pick When
Your pool is closer to a square 16×32, in which case the CIDNN 16×32 mesh fits with less overlap to manage.
The 15×30 version of the high-shade tan cover brings the same 99% light blocking to smaller pools. For homeowners with compact backyards and a tight rectangle, the dense weave buys the same algae-suppression benefit as the larger sibling without forcing a custom fit.
Smaller fabric also means easier solo handling. One person with a helper can usually complete installation in a couple of hours, which is a real time savings over the bigger covers on this list.
Useful Touches
- 99% shading on a compact 15×30 footprint for smaller residential pools
- Polypropylene build resists tearing and supports weight
- Tan color disguises seasonal pollen and dust between cleanings
- Full hardware kit included for straightforward installation
Small Limitations
- Denser weave traps more rainwater, so a cover pump is worth adding
- 15×30 size only fits smaller rectangles, not standard 16×32 pools

Where A Sibling Pick Shines
Your pool measures 16×32, in which case the CIDNN 16×32 99% shading cover fits without overlap gaps.
The Real Relax solar cover is a different category than the mesh safety covers above. The 16 mil bubble blanket floats on the water surface and uses trapped solar heat to keep the pool warmer overnight, which is the right tool for in-season use in mild climates rather than winter shutdown.
For homeowners in places where the pool never fully closes, the bubble cover reduces evaporation, keeps debris out, and extends the swimming season by a few weeks on either end of summer. In harsh winter regions, it works best as a complement to a winter cover rather than a replacement.
Everyday Wins
- 16 mil thickness holds more heat than thinner 8 or 12 mil blankets
- Bubble design traps solar warmth and reduces overnight heat loss
- Cuts evaporation to conserve water and pool chemicals
- Available in 16×32 to match the most common rectangle size
Honest Caveats
- Not a safety cover, so it will not support weight or qualify as a pool barrier
- Needs trimming or a reel for easier on-and-off handling at 16×32
Best Suited To
Pool owners in warm climates who want to extend the swimming season and reduce evaporation during active use.
Not Your Match When
You need a winter safety cover, in which case the CIDNN mesh or high-shade safety covers are the right tool for the job.
What Matters Most Before Choosing a Roll Out Pool Cover
Measure the pool twice before anything else. A 16×32 cover on an 18×36 pool leaves a wide exposed border that catches wind and debris, while an 18×36 cover on a 16×32 creates dangerous slack. Note whether the pool has a step section, and if so, which side it sits on and how large the cutout runs.
Next, weigh the mesh versus high-shade tradeoff. Standard mesh drains rainwater freely and stays lighter on the anchors, but lets in enough light to feed algae over a long winter. The 99% shading covers block nearly all light, which keeps the water clearer, but they hold more rainwater on top and call for a cover pump during wet months.
Finally, think about the climate and how the pool is used. A bubble solar cover extends the swimming season in mild regions, while a mesh safety cover is the right call for a full winter shutdown. Solo installers should favor smaller footprints and lighter mesh, while two-person jobs can tackle the larger rectangles more comfortably.
Key Considerations Across These Picks
Where Shoppers Go Wrong
A common slip is ordering by the pool’s nominal size without measuring the actual waterline, which often runs a foot or two short on each side. CIDNN’s covers add about 2 feet of coverage for anchor placement, so confirming the exact rectangle keeps the fit correct.
Another trap is buying a safety cover when a bubble blanket is what the situation actually calls for, or vice versa. Solar covers are not rated for weight support, so treating them as a safety barrier is a real risk around children and pets.
When Paying More Pays Off
The jump from standard mesh to 99% shading shows up most clearly at spring opening. The denser weave blocks the light that feeds algae, so the water underneath is often clearer and easier to balance without a heavy chemical reset.
That upgrade is worth it where leaf fall is heavy, where the pool sits under trees for most of the day, or where the homeowner values a quick spring startup over saving a few dollars on the cover itself.
Frequently Asked Questions
How do I know which size cover fits my pool?
Measure the waterline length and width at the longest points, then pick the cover that matches. The CIDNN covers add about 2 feet of overhang for anchor placement, so the cover should be slightly larger than the waterline.
Can a roll out pool cover support the weight of a person or pet?
The mesh safety covers on this list are designed to support weight when properly anchored with the included brass anchors and steel springs. The bubble solar cover from Real Relax is a flotation blanket, not a safety cover, and will not support weight.
Do mesh covers let rainwater through?
Yes, standard mesh sheds rainwater through the weave, so puddles do not collect on top. The 99% shading covers are denser and hold more water, which is why a cover pump is a useful add-on for that style.
How are these covers installed?
Installation involves drilling brass anchors into the deck around the pool, attaching steel springs to the cover straps, and tensioning the fabric taut. A drill, basic hand tools, and a helper are usually enough for a first-time setup.
When should I cover the pool for winter?
Most homeowners cover the pool once water temperatures drop consistently below 60 degrees, which slows algae growth and reduces the chemical demand. A bubble solar cover can stay on the water through the active season and come off before the safety cover goes on for winter.
Bottom Line
The right roll out pool cover comes down to your pool’s exact dimensions, whether it has a step, and how much debris and sunlight you need to keep out. The CIDNN mesh line covers every common rectangle and step configuration, while the 99% shading versions handle the heaviest leaf fall. For warm climates, the Real Relax bubble blanket extends the swim season without the weight and anchor hardware of a safety cover. Measure the waterline first, pick the matching shape, and the rest of the decision falls into place.
