Calculating Pool Volume

Before you can determine the correct dosage of any chemical added,
it is important to know the volume of water your pool holds.
These equations are used to determine your pool volume in gallons. All
your measurements are in feet, example: use 12.5’ instead of 12’ 6”.
1. Determine the average depth of your pool
_________ ft + __________ ft = ________ ft ÷ 2 = _________ feet
(deep end depth) (shallow end depth) (average depth)
2. Calculate your pool’s capacity using one of the
formulas below
Rectangular or square pool:
_______ ft x _______ ft x ______ ft x 7.5 = _______ gallons
(length) (width) (average depth) (pool capacity)
Oval pool:
_______ ft x _______ ft x ______ ft x 5.9 = _______ gallons
(short diameter) (long diameter) (average depth) (pool capacity)
Circular pool:
_______ ft x _______ ft x ______ ft x 5.9 = _______ gallons
(diameter) (diameter) (average depth) (pool capacity)
Free form pools:
_______ sq ft x ______ ft x 7.5 = _______ gallons
(surface area) (average depth) (pool capacity)
