What is Pool Volume Calculator?

Calculate the exact water volume of any swimming pool shape — rectangular, circular, oval, or L-shaped. Enter dimensions and depth (constant or variable from shallow to deep end) to get volume in gallons and liters, plus estimated fill time and chemical dosing guidance.

How to use

  1. Select your pool shape (rectangular, circular, oval, L-shaped, or kidney) and enter dimensions in feet or meters.
  2. Set the depth — constant depth or variable with shallow end and deep end values.
  3. View the calculated volume in gallons and liters, along with estimated fill time and chemical treatment amounts.

Result

Rectangular pool 30ft × 15ft, shallow end 3ft, deep end 8ft: approximately 18,563 gallons. At typical garden hose flow, that's about 37 hours to fill.
