Getting ready to winterize your swimming begins with purchasing the correct size cover. Here a few tips that will help you choose the correct size.

Things You'll Need

Tape measure

Note pad and pen

Step by Step


Step 1

Measure the size of the pool. Make certain to include the top rails in your measurements. Some pools have wider top rails that need to be taken into account. Record your measurements in a note pad.

Step 2

Take into consideration how low you will drop the water level. Most pool covers will come with enough material to compensate for a water level that is reduced up to 12". If you need to drain the water level more than that, you will need to purchase a larger cover.

Step 3

Once you have selected the style of winter cover (solid or mesh, you will want to review the cover size. Two sizes will usually be displayed on the item page, the pool size and cover size. For example if you have a 12' round pool, the cover size will be 16' round.

Step 4

Once you have received your new winter cover, carefully remove it from the box and measure it to ensure it is the correct size. If it is incorrect, please contact the dealer you purchased the cover from for further instruction.

Hello Marnita - You would use a standard winter cover for winterizing the pool. When ordering, you would select the cover for an 18' pool size. The actual measurement for the cover will be 21'-22', depending on the specific model.

Anonymous (pool cover) - For a 33'x18' AG pool, you would want a 37'x21' winter pool cover.

We have a 33' x 18' above ground pool - what size cover do we need?

Sady - Yes, you can use a 22' winter cover on you 16 ‘round pool. It's better to have a little more overlap than not quite enough with the 18’ option.

My above ground pool size is 15 x 24 but I have a walking deck around 3/4 of the pool and a larger deck area on the end. What size cover do I get?

InyoPools Product Specialist  Posted: 9/13/2015 

pool cover - All of the covers sold are 4' larger than the size of the pool to allow for a 12" drop in water. Your pool size fits between two sizes sold so you would want to get the larger size of the two.

This still doesn't say how much bigger pool cover should be. My round pool measures 25-1/2 feet across. Allowing for a 12 inch drop in water, what size should I buy?

Pool Measurement - If it's a circular pool, measure the diameter. For an oval, measure the longest and shortest diameter.

you never said HOW to measure the pool...around the circumference or across the diameter?
