Free pool calculators
Two calculators on the same engine as the 3D designer: how much water a pool of any shape holds, and how high each step should be.
Pool volume calculator for any shape
Water volume, surface, fill time, skimmers and heat pump size for ten shapes, measured from the real outline instead of multiplied by a fixed factor.

Pool step height calculator
Rise, tread and number of steps for your pool's depth, counting the first step down from the coping the way the designer does.

What is behind them
Both calculators use the designer's own rules: the ones that draw the pool in 3D and print the figures on every plan page. A number here is the number there.
They are free, need no account and work in metres or in feet. The step calculator runs in your browser; the volume calculator sends the pool's size, and nothing else, to PoolPlanner to be worked out.
The answers are planning figures, not a quote and not an engineer's drawing. Ask your builder to confirm anything that will be built or ordered.
Go on — put a pool in your garden.
