About this calculator
Pool volume is the number every other pool decision hangs on — pump size, filter size, heater capacity and every chemical dose. Get it once and keep it.
For a pool with a shallow and a deep end, use the average of the two depths.
What it assumes
- Volume uses the average of the shallow and deep depths, which is close enough for a regular slope.
- Steps, benches and sun shelves reduce the real volume slightly.
- Chemical figures are a starting point — always dose to your own test readings.
FAQ
Frequently Asked Questions
Every chemical dose is per volume of water, and the pump and filter are sized from it. Guessing the volume is the usual reason a pool is hard to keep clear.
