Pool Volume Calculator

Pool gallons = L × W × avg-depth × 7.48.

Inputs

(shallow + deep) / 2.

Result

Pool volume
19,150 gallons
2,560 ft³.
  • ShapeRectangular
  • Surface area512 ft²
  • Volume (ft³)2,560
  • Volume (gallons)19,150
  • Volume (m³)72.5
  • Liters72,491

Step-by-step

  1. V = L × W × D = 32 × 16 × 5 = 2,560 ft³.
  2. Gallons = ft³ × 7.48052 = 19,150 gal.

How to use this calculator

  • Enter pool dimensions and average depth.
  • Pick shape (rectangular/oval/kidney).

About this calculator

Pool volume in gallons drives chemical dosing (chlorine, pH adjusters), pump-cycle calculation, and heater sizing. Average depth is (shallow + deep) / 2 — a rough approximation for most residential pools.

Frequently asked

(shallow-end depth + deep-end depth) / 2. For a constant-depth pool, just use that depth.
