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 for further instruction.

I have a rectangle pool without steps that measures 13 wide and 38 long. I am needing it anchored to my concrete. What size pool cover should I get? Also, do you recommend mesh or regular?

Is this an inground or above-ground pool? It sounds like you are describing an inground pool safety cover and not a basic winter cover.

I have 27’ round above ground what size cover should I buy.and what size pillows.

InyoPools Product Specialist  Posted: 7/29/2021 

You have a 27' round pool; you purchase a cover titled "For 27' Round Pool" if you go to our winter cover section. If you do not see one that is your size, go to the next biggest one; so in this case, it would be a 28' is usually the next biggest size.As for the pillow, the 4'x8' Air Pillow - PL0195 would be the best choice, but the larger 8'x15' Air Pillow - PL0196 would work as well.

what size pool cover should I get for a 20 Foot round above ground pool 54" deep

InyoPools Product Specialist  Posted: 7/27/2021 

You would pick a pool cover meant for a 20-foot round pool or the next largest size. A suitable cover would be the Pool Winter Cover for 21 ft Above Ground Pool.

I have a 10x16 oval pool. I always get the 10x16 cover but it always pulls and never has enough cover to lay flat on the water. Then when you put the pool pillow (ice compensator) it even makes it less. I’m not really sure what size cover to get. The 10x16 is not sufficient even though they say the cover is about 14 x 19. Never have enough slack. Can you recommend what cover size to get. My pool is also semi in the ground. Thank you.

Hey Jay. I am having the same problem! Did you ever come up with a solution on what size cover to go with??

InyoPools Product Specialist  Posted: 8/3/2021 

How much slack do you think you need to have the cover lay flat. Do you need two or three extra feet or more? That would determine how much larger of a cover you need.

What size cover do I need for 18x48 pool and I drain it halfway

InyoPools Product Specialist  Posted: 5/21/2021 

You would probably want to go a size up, to a cover meant for a 20 or 21 foot round pool.

I have a 10x 30 pool, what are the size specifications needed?

InyoPools Product Specialist  Posted: 5/13/2021 

Ideally, you would want a cover that is wide enough to cover the 10-foot width and long enough to cover the 30-foot length with enough overhand to accommodate water bags to secure it. So a 15' X 35' cover size would suffice.

What kind of cover do I need for the summer. First time with permanent pool. Owner

InyoPools Product Specialist  Posted: 9/2/2020 

A cover really isn't necessary for in-season use, but if you want to keep the pool at a omfortable temp, a solar cover is the way to go.

My pool size is 16 and a half feet wide by 27 and a half feet long what size pool cover should I get?

InyoPools Product Specialist  Posted: 12/26/2019 

As we have said in previous comments, you can use a cover that is equal to or larger than the width and lengths you listed. For example, you can use an 18 X 28 pool cover, but you could not use a 17 X 25.

I'm very late closing my pool...I have a rectangular inground pool that measures 17' 1/2 wide 38' long...can you advise what size pool cover I would need.

InyoPools Product Specialist  Posted: 11/25/2019 

For your size swimming pool, we carry the 20 by 40 winter cover which is the next size larger than your size. This should not be an issue for a standard inground swimming pool. Now, if you need a safety/mesh cover that will be anchored to your deck then you would need to fill out and submit this custom cover form so we can get you an estimate asap.

We have an oval above ground pool which is 12 feet by 28 feet. What size winter cover do I need.

InyoPools Product Specialist  Posted: 10/15/2019 

Winter covers are listed by the pool size they are meant to fit. If your pool size is not listed, then you would use a cover whose length and width measurements are equal or greater then your pool's.

I have a pool with one side radius 10'.1/4, another side radius 8'.1/4. Could you guy show me where can i order this winter cover tarp?

 Posted: 3/23/2018 

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?

InyoPools Product Specialist  Posted: 7/24/2017 

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.

I have a 16' round pool, can I use a 22' winter cover for it

InyoPools Product Specialist  Posted: 8/21/2016

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.

Anonymous  Posted: 9/12/2015 

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?

InyoPools Product Specialist  Posted: 11/19/2014 

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

Anonymous  Posted: 11/18/2014 

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