A pool cover sits over the water to keep out leaves and debris, and some types also help hold in warmth. The main types are solid winter covers, mesh covers, solar blankets and automatic systems, and each differs in material, sizing method and how it is held in place.
This guide is for pool owners who want to understand the options before buying. We have not used these products ourselves; we compare the information in each listing, so confirm the fit and installation details with the maker. Read the table below and match each factor to your pool and the season you plan to cover it for. Think about who will put the cover on and take it off, because a design that suits two people may be awkward for one, and note where you will keep it between uses.

What to Look For
| Factor | Why it matters | What to check |
|---|---|---|
| Cover type | Solid, mesh and solar types do different jobs. | Decide whether you need debris cover, heat retention or both. |
| Pool shape and size | Round, oval and rectangular pools need different cuts. | Measure the pool and compare with the maker’s size guide. |
| Material | Fabric weight and weave change durability and handling. | Read the material description and any notes on sun exposure. |
| Anchoring method | Water bags, straps and anchors hold the cover down. | Check what hardware is included and what you must buy. |
| Drainage | Rain and melt water must go somewhere. | Look for notes on mesh panels or drain features. |
| Overhang | Extra fabric around the edge helps the cover sit evenly. | Check the overhang the maker lists. |
| Storage | Large covers take space when folded. | See whether a storage bag or reel is offered. |
Setup and Care Tips
- Measure the pool at the widest and longest points, not the nominal size.
- Clean the water and balance it as usual before the cover goes on.
- Follow the maker’s anchoring guidance for your pool type.
- Remove leaves, snow and standing water from the cover as the maker advises.
- Clean and dry the cover fully before you fold and store it.
Mistakes to Avoid
- Ordering by the pool’s marketed size without measuring.
- Choosing a solid cover and ignoring how rain will be handled.
- Skipping anchors or bags the maker calls for.
- Folding the cover while it is still damp.
- Buying a heavy cover without a plan to handle it.
FAQ
What is the difference between a solar cover and a winter cover?
A solar cover floats on the water and is mainly meant to help retain warmth. A winter cover is built to stay on through the off season and is held down with anchors or bags. Read the maker’s notes for the intended use.
Will one cover fit an odd-shaped pool?
Some makers offer custom sizes or trim-to-fit designs, while standard covers suit regular shapes. Measure carefully and ask the maker if your pool has steps, a bump-out or other features.
The Short Version
Pool covers differ by type, size, material and anchoring. Measure your pool, read the maker’s fit notes, and choose a cover that matches the season and the job you want it to do.
