Pool Volume Calculator

Estimate water volume using average depth and a simple rectangular or circular shape.

About the Pool Volume Calculator

Approximate pool capacity using plan dimensions and average depth.

How to use it

  1. Choose rectangular or circular shape.
  2. Enter applicable dimensions and average depth.
  3. Calculate volume in three units.

Formula

Rectangular volume is length times width times average depth. Circular volume is pi times radius squared times average depth.

Example

A 10 m by 5 m pool averaging 1.5 m deep holds about 75 m³ geometrically.

Notes

Steps, slopes, curves, freeboard and displacement are excluded, so real capacity may differ.
