About This Calculator

Knowing your pool's exact water volume is essential for proper chemical dosing. Too little chemical won't sanitize effectively; too much wastes money and can damage equipment. This calculator helps you determine your pool's volume based on its shape and dimensions.

How It Works

Select your pool shape, enter the dimensions, and specify the shallow and deep end depths. The calculator computes the average depth and total volume in both gallons and liters.

Frequently Asked Questions

Use a tape measure for length and width at the waterline. For depth, measure from the waterline to the bottom at both the shallow and deep ends.
