How it works
gallons = length × width × avg depth × 7.48average depth = (shallow + deep) ÷ 2
- length
- pool length in feet
- width
- pool width in feet
- avg depth
- average of the shallow and deep ends
For a sloping floor, use the average of the shallow and deep-end depths. Round and oval pools use a different formula.
Frequently asked questions
How many gallons is my pool?
Multiply length × width × average depth in feet, then by 7.48.
How many gallons in a 32 by 16 ft pool?
About 19,150 gallons at a 5 ft average depth.
What is average depth?
The shallow-end depth plus the deep-end depth, divided by two.
Does this work for a round pool?
No, a round pool uses π × radius² × depth × 7.48.
