Construction and Materials
Pool Volume Calculator
Calculate rectangular, circular, or oval pool volume from dimensions and average depth in cubic feet, gallons, liters, and cubic meters.
Formula
Volume = plan area x average depth; rectangular area = LW, circular = pi D^2/4, oval = pi LW/4.
About the Pool Volume Calculator
Calculate rectangular, circular, or oval pool volume from dimensions and average depth in cubic feet, gallons, liters, and cubic meters.
How the Pool Volume Calculator Works
The selected plan shape defines surface area, shallow and deep depths are averaged, and cubic feet are converted with 7.48051948 US gallons per cubic foot.
Formula
Volume = plan area x average depth; rectangular area = LW, circular = pi D^2/4, oval = pi LW/4.
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.

Accuracy and Limitations
Sloped floors, steps, benches, curved walls, freeboard, irregular shapes, and manufacturer dimensions can change actual water volume. Metered fill is more accurate.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
