Spike's Calculators

Calculate a pool's surface area from the volume and the depth of the pool. Some pool owners don't know what the surface area of their pool is, but they do know the amount of water it takes to fill the pool.

If you can calculate pool volume from square footage and average depth, you can get a reasonable estimate of the surface area square footage from the pool's volume and average depth.

This calculator will give you a reasonable estimate of square feet of your pool's surface area.

- the number of gallons (US liquid) it takes to fill your pool
- the average depth of the pool (take a measurement at the shallow end and one at the deepest end of the pool. Add them together and divide by two).

- the surface area of your pool in square feet
