Frequently Asked Questions
- Pool size usually refers to volume. For rectangular pools, multiply length x width x average depth. For round pools, use pi x radius^2 x average depth.
- If you know the pool volume in cubic feet, multiply by 7.4805 to get US gallons.
- If the pool has a shallow and deep end, add the two depths and divide by 2 to estimate average depth.
- Yes. The volume formulas work for many above-ground and in-ground pools if the shape is close to rectangular or round.
- Use Volume = length x width x average depth.
- Use Volume = pi x radius^2 x average depth.
- Pool volume helps with water treatment, heating calculations, refilling, and equipment planning.
- No. It is most accurate for simple shapes. Freeform pools may need to be broken into smaller shapes for a better estimate.
