What is Pool Volume Calculator?
The Pool Volume Calculator works out how much water your pool holds - in gallons, liters, and cubic feet - from its shape and dimensions. Four shapes are supported (rectangular, circular, oval, kidney), plus pump turnover time and a chlorine dosing estimate for a target ppm rise.
Key Benefits
- Dose chemicals correctly based on true water volume
- Know how long to run your pump for a full turnover
- Four shapes cover most residential pools
- Gallons and liters together match any product label
- Instant, private math - perfect for pool season
Common Use Cases
- •First-time pool owners learning maintenance dosing
- •Verifying chlorine or algaecide amounts before adding them
- •Sizing a replacement pump by checking turnover time
- •Planning water replacement or refill costs
- •Opening or winterizing a pool with accurate shock math
How to Calculate Pool Volume
- Pick the shape: Choose rectangular, circular, oval, or kidney - the needed dimensions update automatically.
- Measure and enter dimensions: Enter length and width (or diameter), plus the shallow and deep end depths.
- Add pump and dosing data: Enter your pump flow rate in GPH and a chlorine target in ppm for the extra estimates.
- Read volume and estimates: See gallons and liters up top, with cubic feet, average depth, turnover hours, and a bleach dose below.
