VEVOR Round Solar Pool Covers: Sizes, Thickness & Fit Guide

If you want to keep your above-ground pool warmer without running a heater all day, a VEVOR round solar pool cover is one of the simplest upgrades you can make.

The right cover helps reduce heat loss, limit evaporation, keep more debris out of the water, and make your pool feel warmer for longer after sunny days. The key is choosing the correct round size and thickness for your pool.

This guide compares the main VEVOR round solar pool cover sizes, explains when to choose 8mm, 12mm, or 16mm, and shows how to measure, fit, trim, and use the cover properly on a round above-ground pool.

Quick verdict: which VEVOR round solar pool cover should you choose?

For most round above-ground pools, the 12mm VEVOR solar cover is the best balance of heat retention, price, and everyday handling.

Choose 8mm if you want the cheapest and lightest option for mild weather or daily use.

Choose 16mm if you want stronger heat retention, better durability, and longer season extension, especially for larger pools or cooler evenings.

If your round pool size falls between two cover sizes, choose the larger option and trim it to fit. VEVOR solar covers can be cut to match the shape of your pool, which makes them more flexible than a fixed-size hard cover.

VEVOR round solar cover sizes

Use this section to match your round above-ground pool to the closest VEVOR solar cover size. If your pool falls between two sizes, choose the larger cover and trim it to fit your pool shape.

VEVOR solar covers are designed to be cut down when needed. Place the bubble side down, mark the excess material, trim carefully with scissors, and test the fit inside the pool before making any final adjustments.

VEVOR solar covers can be trimmed to fit the exact shape of your pool. This is useful if your pool size is slightly smaller than the cover, or if you want the cover to sit neatly inside the pool wall instead of overlapping too much.

Own an oval pool?

If you own an oval above-ground pool, a round cover usually will not be the best starting shape. In most cases, a rectangle solar cover is easier to trim into an oval shape because it gives you more usable material at the sides and ends.

For oval pools, see our VEVOR rectangle solar pool covers guide, where we explain how rectangle covers can be cut to fit oval and custom pool shapes.

Available VEVOR round sizes:

• 10 ft round — 15mm — Best for very small plunge pools / kiddie pools.

  
  

• 15 ft round — 12mm — Great entry-level above-ground pools; good balance of cost & retention.

  
  

• 18 ft round — 12mm — Common above-ground size; 12mm gives solid season extension.

  
  

• 18 ft round — 16mm — Upgraded option for longer season or windier locations.

  
  

• 24 ft round — 8mm — Budget option for mild climates or where you use the cover daily.

  
  

• 24 ft round — 12mm — Best all-around choice for 24 ft pools — balance of cost and retention.

  
  

• 24 ft round — 16mm — Top choice if you want maximum insulation and durability.

  
  

• 27 ft round — 16mm — Large above-ground pools — thicker bubble helps retain heat overnight.

  
  

• 33 ft round — 8mm — Very large pool; 8mm helps cut cost but expect slower heat retention — pair with long run times and a reel.

Which VEVOR solar cover thickness is best?

VEVOR round solar pool covers are usually available in different thickness options, including 8mm, 12mm, and 16mm. The thicker the cover, the better it usually performs for heat retention and durability. The trade-off is that thicker covers are heavier and harder to remove without a reel.

For most above-ground pool owners, 12mm is the safest all-round choice.

8mm VEVOR solar covers: best for budget and easy handling

Choose an 8mm VEVOR solar cover if you want the cheapest and lightest option. This thickness is best for mild climates, smaller pools, or pool owners who plan to remove and replace the cover frequently.

The trade-off is heat retention. An 8mm cover can still reduce evaporation and help hold warmth, but it will not insulate as strongly overnight as a thicker 12mm or 16mm cover.

12mm VEVOR solar covers: best for most round above-ground pools

A 12mm VEVOR solar cover is the best choice for most round above-ground pools. It gives you a stronger balance of warmth, durability, price, and handling.

Choose 12mm if you want better heat retention than a basic cover but do not want something so heavy that it becomes annoying to use every day.

16mm VEVOR solar covers: best for maximum heat retention

Choose a 16mm VEVOR solar cover if you want the strongest heat retention and durability. This is the best option for larger round pools, cooler evenings, windy yards, or pool owners who want to extend the swimming season as much as possible.

The downside is weight. A 16mm cover is more awkward to handle, so a pool cover reel becomes much more useful.

Best VEVOR round solar cover by pool size

For small round pools, a lighter 8mm or 12mm cover usually makes the most sense because it is easier to handle and remove.

For common 18ft and 24ft above-ground pools, 12mm is usually the safest choice because it gives you better heat retention without becoming too heavy.

For larger 27ft to 33ft pools, a 16mm cover is worth considering if you want stronger overnight heat retention. Just remember that larger, thicker covers are much easier to manage with a reel.

How to measure a round pool for a proper cover

Step-by-step measurement:

1. Measure the diameter across the widest point — use a tape measure from edge to edge through the center. If your pool has a skirt or top rails, measure to the inside edge of the rail that the cover will rest on.

2. Round up to the nearest common cover size. If your pool measures 23'2", choose a 24ft cover; a cover slightly larger is better than slightly smaller.

3. Account for overlap if you want a 6–12" crossover to avoid wind lift (helpful in windy yards). Most VEVOR covers are sized to sit on the top rail; follow the product listing notes.

4. Note special cases: if you have a deck that touches the pool or nonstandard rails, measure carefully and consider a custom cover or tie-down kit.

Installation & securing tips for round above-ground pools

Quick install checklist

• Clean pool surface & remove debris before installing.

• Spread cover bubble side down (bubbles facing water) for best solar absorption.

• Center the cover and smooth out wrinkles; allow a small overlap over the rail.

Handling & reels

• For 16mm covers (heavy), use a sturdy reel (if possible) or two people to remove/install. Reels make daily use practical and reduce wear.

• Use anti-tear edge reinforcement and avoid dragging across rough surfaces.

Common fit problems and how to fix them

Cover too small

If the cover is too small and leaves visible gaps around the pool edge, exchange it for the next size up if possible. A small cover will still help, but exposed water loses more heat overnight and allows more evaporation.

For best results, the cover should sit neatly across the water surface with minimal gaps.

Cover too large

If the cover is slightly too large, trim it to fit your pool. VEVOR solar covers can be cut to size, so it is usually better to choose a slightly larger cover than one that leaves gaps around the edge.

Lay the cover bubble side down on the water, let it settle, then mark the excess material carefully. Trim slowly with scissors and avoid cutting too much at once. A snug fit helps reduce heat loss, evaporation, and wind lift.

Wind lift

If expecting high winds or if your pool is set up in a windy location, use an additional pool cover (over solar cover) which can be secured with a either a winch kit, water bags, tie straps or a proper cover rope.

Pros & cons of VEVOR round solar covers

Pros

• Strong value for money vs premium brands.

• Wide range of sizes and thickness options — easy to match to your pool.

• Works well with saltwater pools when chemistry is maintained (bubble covers are inert).

• Lightweight 8/12mm options reel easily; thicker options last longer.

Cons

• Thicker 16mm covers are heavy and need stronger reels or help to handle.

• Some listings combine sizes/thickness in one product group; confirm exact size/thickness before checkout.

FAQ

Which VEVOR solar cover thickness is best for a round above-ground pool?

For most round above-ground pools, a 12mm VEVOR solar cover is the best choice. It gives you a good balance of heat retention, durability, price, and everyday handling. Choose 8mm if you want the lightest budget option, or 16mm if you want maximum heat retention.

Can you cut a VEVOR round solar pool cover to fit?

Yes. VEVOR solar pool covers can be trimmed to fit your pool shape. If your pool falls between two sizes, choose the larger cover, place it bubble side down, mark the excess material, and trim it carefully with scissors.

Should the bubbles face up or down on a VEVOR solar cover?

The bubbles should face down toward the water. This helps the cover sit properly on the pool surface and improves heat transfer from the sun into the water.

What size solar cover do I need for a 24ft round pool?

For a 24ft round pool, choose a 24ft round solar cover. If you want the best all-round option, a 12mm cover is usually the safest choice. Choose 16mm if you want stronger heat retention and do not mind the extra weight.

Can I use a round solar cover on an oval pool?

A round solar cover is usually not the best choice for an oval pool. A rectangle solar cover is often easier to trim into an oval shape because it gives you more material to work with along the sides and ends.

How long does a VEVOR solar pool cover last?

A VEVOR solar pool cover can last several seasons, depending on thickness, sun exposure, pool chemistry, storage, and how carefully it is handled. Thicker covers usually last longer, while thinner covers are lighter but more prone to wear.

Final recommendation — why every above-ground pool needs a solar cover

If you own an above-ground pool, a solar cover should be one of the first upgrades on your list. It’s the cheapest, simplest, and most effective way to keep heat in, cut evaporation, and dramatically lower your heating and chemical bills — no expensive gear required!
