Pool Water Volume Calculator

To calculate the volume of a oval-shaped swimming pool measure radius A and B of your pool and the depths at the shallow and the deep ends. Then, simply type your dimensions into the calculator. We will take care of the heavy lifting!

The equation to calculate the volume in gallons of a oval pool is:

volume = π x radius a x radius b x average depth x 7.48

*π = 3.14

*average depth = (depth 1 + depth 2) / 2

To calculate the volume of a kidney-shaped swimming pool measure the length, widths A and B of your pool and the depths at the shallow and the deep ends. Then, simply type your dimensions into the calculator. We will take care of the heavy lifting!

The equation to calculate the volume in gallons of a kidney pool is:

volume = 0.45 (width a + width b) x length x average depth x 7.48

*average depth = (depth 1 + depth 2) / 2

To calculate the volume of a square-shaped swimming pool measure the side length of your pool and the depths at the shallow and the deep ends and simply type them into the calculator. We will take care of the heavy lifting!

The equation to calculate the volume in gallons of a square pool is: 

volume = L² x average depth x 7.48

*average depth = (depth 1 + depth 2) / 2

To calculate the volume of a rectangle-shaped swimming pool measure the length and width of your pool and the depths at the shallow and the deep ends. Then, simply type your dimensions into the calculator. We will take care of the heavy lifting!

The equation to calculate the volume in gallons of a rectangle pool is:

volume = length x width x average depth x 7.48

*average depth = (depth 1 + depth 2) / 2

To calculate the volume of a trapezoid-shaped swimming pool measure lengths A and B, the width of your pool and the depths at the shallow and the deep ends. Then, simply type your dimensions into the calculator. We will take care of the heavy lifting!

The equation to calculate the volume in gallons of a trapezoid pool is:

volume = ((length a + length b) /2) x width x average depth x 7.48

*average depth = (depth 1 + depth 2) / 2

To calculate the volume of a triangle-shaped swimming pool measure the length and width of your pool and the depths at the shallow and the deep ends. Then, simply type your dimensions into the calculator. We will take care of the heavy lifting!

The equation to calculate the volume in gallons of a triangle pool is:

volume = (length x width) /2 x average depth x 7.48

*average depth = (depth 1 + depth 2) / 2
