Calculate your swimming pool volume in gallons and liters. Supports rectangular, round, oval, L-shape, and freeform pools with shallow/deep end calculations.
Select your pool shape (rectangular, round, oval, L-shape, or freeform) and enter the dimensions. The calculator uses the average of your shallow and deep end depths to compute volume.
The calculated volume is automatically shared with all other chemical calculators on PoolDose. Calculate your pool volume first for accurate chemical dosing results.
Both US units (feet/gallons) and metric units (meters/liters) are supported. For freeform pools, the estimate may vary by 5-10% from actual volume.
Select your pool shape (rectangular, round, oval, L-shape, or freeform), enter the dimensions and depths, and the calculator will compute the volume in both gallons and liters. For pools with a shallow and deep end, enter both depths and the calculator uses the average.
Knowing your pool volume is essential for accurate chemical dosing. All pool chemical calculators require the pool volume to determine the correct amount of chemicals to add. An incorrect volume estimate leads to under- or over-dosing.
The calculator provides a close estimate based on standard geometric formulas. For freeform pools, the estimate may vary by 5-10% from actual volume. For the most accurate results, consider having your pool professionally measured.
A typical residential inground pool holds between 10,000 and 25,000 gallons. A standard 12x24 ft rectangular pool with an average depth of 5 ft holds approximately 10,800 gallons. Above-ground pools typically hold 5,000-15,000 gallons.
