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.

## Calculating Your Pool’s Square Footage and Required Tile Quantity for Your Project

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 the total square footage of your swimming pool’s interior.

While this formula provides a good guideline for determining the number of tiles required to finish a pool, it’s important to note that most pools have round corners and steps, making it an approximate calculation. We suggest rounding up the measurements and adding an additional 5-8% more tiles to account for waste.

To ensure that you have enough tiles for your project and avoid running out towards the end, it’s critical to obtain an accurate estimate and account for any additional tiles required.

**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 the average depth in a pool where the bottom slopes are: 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 pool floor + 384 sqft (the two long sides) + 64 sqft (shallow side) + 128 sqft (deep side) = 1088 SQFT.

## Calculating the Square Footage of Your Swimming Pool’s Waterline

To calculate the square footage of the waterline of your swimming pool, you need to measure the pool’s perimeter at the waterline and the height of the waterline. Follow these steps:

1 – Measure the** perimeter of the pool** at the waterline using a tape measure. You can follow the steps in the section below to calculate the perimeter.

2 – To calculate the height of the waterline in your pool, measure the distance from the bottom of the coping to the point just below where the water meets the wall at its highest point. To ensure the appropriate water level of your pool, you can use the skimmer as a guide. Ideally, the water level should be maintained between one-third to one-half of the skimmer opening for optimal performance. This is because the skimmer functions best when it’s covered with pool water halfway.

Typically, homeowners choose to tile from the coping to a few inches below it, or they use the tile’s width multiplied by the perimeter to come up with the sqft for their waterline materials.

3 – Multiply the perimeter by the height to get the square footage of the waterline. For example, if the perimeter of your pool at the waterline is 80 feet and the height of the waterline is 1.5 feet, then the square footage of the waterline would be 120 square feet (80 x 1.5 = 120).

Determining the Perimeter of Your Swimming Pool

To calculate the perimeter of a swimming pool, you need to measure the length and width of the pool at the waterline. The perimeter is the distance around the pool’s edge.

Follow these steps to calculate the swimming pool perimeter:

1 – Measure the length and width of the pool at the waterline using a tape measure. Make sure to measure the longest parts of the pool to get the most accurate measurements.

2 – Add the length and width together to get the total distance across the pool.

3 – Multiply the total distance across the pool (A+B) x 2, for example, to get the distance around the pool’s perimeter. This is because the pool has two long sides and two short sides.

4 – If the pool has a complex shape or irregular edges, you may need to measure each section separately and add them together to get the total perimeter.

For example, if your pool is 30 feet long and 20 feet wide at the waterline, the total distance across the pool is 50 feet (30 + 20 = 50). Multiplying 50 by 2 gives you a perimeter of 100 feet.

It’s important to note that the square footage of the waterline determines the amount of tile or other decorative material needed for the pool’s waterline. It’s different from the **total square footage of the pool**, which includes the area of the pool’s bottom and walls and is used for determining the amount of material needed for resurfacing or replastering the pool.
