Pool Calculator

To determine how much of each chemical you will need, the first step is to determine the volume of your pool. The following form represents an easy method to calculate pool volume.

Rectangular Pools:
Length x Width x Average Depth x 7.5 = Total Gallons
ft. x ft. x ft. x 7.5 =

Round Pools:
Diameter x Diameter x Average Depth x 5.9 = Total Gallons
ft. x ft. x ft. x 5.9 =

Oval Pools:
Long Diameter x Short Diameter x Average Depth x 6.7 = Total Gallons
ft. x ft. x ft. x 6.7 =
