How Many Gallons Is a Kiddie Pool? Size and Capacity Chart
A small 5 ft (Ø1.5 m) inflatable kiddie pool holds well under 150 gallons, while a large 10 ft 3-ring family pool can reach several hundred. To estimate any round pool, multiply diameter × diameter × water depth × 0.785; for a rectangle, length × width × depth. The chart below gives the upper bound for every kiddie pool in our range.

Calculated upper bound from the outer size at 80% fill, not a catalog figure. Inflatable rings take up part of the volume, so real capacity is lower; frame pools come closest to this number.
How do you calculate kiddie pool gallons?
Measure the inside, not the outside. For a round pool: inside diameter × inside diameter × water depth × 0.785 gives cubic meters (× 1,000 for liters, ÷ 3.785 for gallons). Kiddie pools are filled only part way, so use the planned water depth, not the wall height.
How do I keep a kiddie pool clean?
- Empty small pools after each day of use and let them dry.
- Cover the pool between uses.
- Skim leaves and rinse the floor before refilling.
- Store clean and dry at the end of the season.

FAQ
How many gallons is a 5 ft kiddie pool?
A Ø1.5 m × 41 cm pool works out to at most about 580 liters (about 150 gallons) at 80% fill on its outer size; with the air rings the real figure is lower.
Do kiddie pools need a filter?
Small kiddie pools are usually emptied after use instead. Larger family pools that stay filled benefit from a filter pump.
