HOW TO ESTIMATE THE CAPACITY OF YOUR
POOL IN GALLONS OF WATER
Rectangular or Square Pools:
Average depth x length x width x 7.5.
Example: Length: 40'
Width: 20'
Depth: 5'
5 x 40 x 20 x 7.5 = 30,000 gallons
Round Pools:
Diameter of the pool x the diameter of the
pool x the average depth of the pool x 5.9.
Example: Diameter: 20'
Depth: 4'
20 x 20 x 4 x 5.9 = 9,440 gallons
Oval Pools:
Average depth x length x width x 5.9 = total gallons
Free Form Pools:
Estimate as closely as you can the number of
cubic feet and multiply this by 7.5, the
number of gallons is each cubic foot.
If pool has sloping sides, multiply gallonage by
0.85. In many instances, your pool contractor
knows how many gallons there are in your pool.
Give him a call; he will be pleased to be of service.
