How to Calculate the Size of Your Pool

So, you just bought your new home with a brand new-to-you pool! Congrats! But what do you do now?

Many people would head right over to pool store, buy a ton of stuff, and try their best to maintain this new pool.

However, most people forget a very important first step. They key to maintaining that pool every week spring rain, sunshine, and even in the winter is to know the size of your pool!

Some of you might already know how many gallons your pool is, and if so, what are you doing here?! We have a bunch of other blogs you can delve into. I recommend looking at which chemicals works best for you.

On the other hand, if you don't know how large or how many gallons are in your pool we are here to help.

Sometimes the previous home owner or realtor may know which would be very useful. It might be wise to ask them if you are able.

If not it's pretty simple! You just need a measuring tape and a little bit of math.

When you are in the industry it can be pretty easy to guage since you can see 10 to 20 pools a day, but if you are a home owner its a different story.

Pools are thousands of gallons! Your can range from 10,000 to 40,000 to pretty much as big as you can imagine.

It's all down to the length, the width, and the depth of your pool.

This is where your tape measure comes in. You will need to measure your pool's length. This works great if you have a rectangle pool but if you have a fancy pool with curves or edges things might get more difficult.

Usually pools are built pretty evenly though so measuring the tip of one point to the other side should suffice in most cases. For very peculiar shapes you will need to guesstimate. A couple hundred gallons won't be very detrimental to the over all number so this will be fine.

Next do the same with the smaller side for your width.

The last part might be more difficult as you will need the depth of your pool. Some people recommend the deepest part of the pool but go to the middle of your pool on the slope and it will give you the average depth.

If you have a metal pool rod you can mark the water line, take it out of the water, and measure the rod instead.

With these numbers you are ready to figure it out. Simply multiply in feet;

Length x Width x Depth x 7.5

The 7.5 is for gallons. There are 7.5 gallons in one cubic foot so this number will bring you to total gallons. So let's take an example.

Say your Length is 30 ft, Width is 15 ft, and Depth is 8 ft.

You would multiply like this;

30 ft x 15 ft x 8ft x 7.5 = 27,000 gallon pool

So you can see with this example your pool would be 27,000 gallons.

But after you calculate this, which do you need to do with this number?

Your gallons in your pool can be used for:

Calculating the amount of chemicals you need,

How long and how many gallons you will need if you ever need to refill it,

The price of repairs and cleaning for your sized pool,

And how much algae can collect during summer months.

Be prepared before you buy chemicals so you don't over chlorinated your pool and leave it stinky or under chlorinate your pool and grow algae.

As always let us know if you have any questions and make sure to check out our other blogs!
