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.
