Factors to Consider When Choosing a Cover for Swimming Pool
When choosing a swimming pool cover, start with your pool’s shape and size to ensure a secure fit. You should also check the material’s thickness and durability, as well as how well it retains heat and blocks evaporation and debris. Finally, choose a cover that is easy for you to install and remove.
Pool Shape And Size
Your pool’s shape and size should guide cover selection from the start, because a proper fit keeps debris out and helps trap heat more effectively. Measure the pool’s maximum length and width, or its diameter if it is round, then add 12 to 24 inches of overlap for easier securing. Match the cover shape to your pool’s contour, rectangular, oval, or round, to reduce trimming and limit gaps. If your pool has an unusual layout, choose a trim to fit cover and mark cut lines before you cut so you keep enough overlap at corners and steps. Also factor in depth changes, steps, ladders, and built in spas so the cover lies flat. If you use anchors or tension straps, leave room for attachment points and strap routing.
Material Thickness And Durability
Once you’ve matched the cover to your pool’s shape and size, material thickness and construction become the next major factors. You’ll usually get better tear resistance and longer service life from thicker materials, such as 12 to 16 mil solar blankets or multi ply winter covers. If your pool sits in a windy spot or gets a lot of debris, look for high denier fabrics or scrim reinforced builds, such as 500D material or 7×7 scrim counts, because they resist punctures better. Check stress points as well. Heat sealed seams, reinforced grommets, and integrated loops hold up far better than basic stitched or glued joints. Do not overlook UV inhibitors or gel coatings either, since sunlight can make thinner covers brittle faster.
Heat Retention Performance
Heat retention depends on how well the cover slows heat loss as much as how much sunlight it captures. You will usually get better insulation from a thicker cover, especially one rated around 12 to 16 mil or built with a dense fabric, because it cuts nightly heat loss more effectively than thin film. Bubble or air cell designs also help by trapping solar energy and adding a thermal layer; tightly spaced bubbles improve daytime heat gain and reduce conductive loss after sunset. Color matters too. Clear or light transmitting covers let more sun warm the water, while darker or reflective surfaces can hold heat differently. A snug fit with minimal overlap keeps exposed water down, and a cover installed bubble side down performs better. UV resistant materials keep doing their job longer.
Evaporation And Debris Control
Beyond holding in warmth, a good pool cover also cuts down on evaporation and keeps out debris. When you choose a properly fitted cover, you can reduce water loss by about 90 to 95 percent, which means you will not need to top off the pool as often. Solid or bubble style solar covers block wind driven evaporation and also trap heat, while tightly woven winter or debris covers stop leaves and dirt from getting in. Look for overlapping edges, drawstrings, or secure straps, since they limit gaps that let air and debris sneak through. If you prefer a mesh winter cover, bear in mind that it stops larger debris but will not limit evaporation as much. Clear off leaves and twigs regularly so they do not stain the cover or decompose into mess.
Ease Of Installation
Ease of installation can make a big difference in how often you actually use your pool cover. If you can handle it alone, you will save time and hassle. Otherwise, plan for a second set of hands. Check built-in fastening systems such as drawstrings, straps, grommets, or loops, and make sure they line up with your pool’s anchor points for a secure fit. Choose lightweight materials with side handles, inflatable centers, or pole supports so you can drape, center, and remove the cover more easily. A pre-sized cover usually installs faster than a trim to fit model, which needs cutting and extra setup. Also consider storage. Foldable covers, machine-washable fabrics, and storage handles reduce maintenance between seasons.
Frequently Asked Questions
How Long Do Solar Pool Covers Usually Last?

Do Pool Covers Help Reduce Evaporation?
Yes, you can reduce evaporation with a pool cover. It helps trap moisture, reduce heat loss, and slow the amount of water escaping into the air. As a result, you will need to refill the pool less often and can save water and money.
How Do I Store a Pool Cover When Not in Use?
Clean and dry your pool cover before folding it, then store it in a shaded, dry place such as a shed or garage. Use a storage bag or reel to help prevent creases, mildew, and damage.
Will a Pool Cover Work With a Pool Heater?
Yes, your pool cover can work with a heater. In fact, covered pools can lose up to 70% less heat, so you can save energy while keeping the water warmer and debris out.
