# How to Measure And Calculate Your Pool Size

Using the following principles, you can easily measure and calculate your pool size and how many tiles you will need to order.

You’ll need a few simple tools to get the most accurate pool measurements:

• A measuring tape – could be digital or laser.
• Pen and paper to write down the measurements.
• A calculator.

How to calculate the amount of tile you will need:

Knowing the square footage of a swimming pool is essential when determining how many tiles you will need to purchase.

Use the information below to estimate of the total square footage of your swimming pool’s interior.

This formula is approximate since most pools likely have round corners and steps, but it gives a good guideline for determining the number of tiles needed to finish a pool. We recommend rounding up on the measurements and we always recommend getting an extra box of tile just in case. You don’t want to run out of tile towards the end of your project.

The formula is as follows:

(L x W) + (L x Avg Depth x 2) + (W x shallow depth) + (W x deep depth) = Total square footage of surface area of all the pool sides and bottom.

To determine average depth in a pool where the bottom slopes: Measure the shallow end and measure the deep end. Add them together and divide by 2. This is the average depth of your pool.

Below is an example using a 16 x 32 pool with a Shallow depth of 4′, a deep depth of 8′, and an average depth of 6′ feet.

L x W = (32 x 16) = 512

L x Avg. Depth x 2 = (32 x 6 x 2) = 384

W x Shallow Depth = (16 x 4) = 64

W x Deep Depth = (16 x 8) = 128

512 sqft for the bottom + 384 sqft (the two long sides) + 64 sqft (small side) + 128 sqft (deep side) = 1088 SQFT.

Advanced digital and laser measurement tools can help get an accurate measurement, although they are not necessary, a simple measuring tape will do the trick. You can also hire a pool tile installer to take the measurements if you want to be extra sure with your calculations. A second opinion never hurts!
