Pool Volume Calculator

Measure length, width, and average depth to get pool gallons, liters, fill cost, and water weight. Every chemical dose starts here.

Inputs

Inputs and assumptions

Measure the longest straight side in feet, water edge to water edge.

Measure the widest straight side in feet.

Average of shallow and deep ends in feet. Sloped floors: add both ends and divide by 2.

From your water bill per 1,000 gallons. US average is about $6.
