The Poolhop Pool Volume Calculator is a free tool that calculates the volume of water in your swimming pool into gallons. It works for both in-ground and above-ground pools including most shapes and varying depths. Select the pool shape closest to yours and enter the length, width, and depth in feet. For variable depth pools, enter the shallow end and deep end depths independently. If your swimming pool has sloping sides or walls, click the Sloping Sides checkbox.
Click the Calculate button to see your swimming pool gallons result. Knowing the accurate volume for your swimming pool water is critically important for regular maintenance and precise pool chemical applications. Your pool water volume will also allow you to use any of our other free online tools for pool chemistry and maintenance.
