How many gallons in a 12x24 pool?
About 9,700 gallons (36,700 liters), with 3 to 6 ft floor. A 12 × 24 suits a smaller yard. It holds about half the water of a 16 × 32, so it is noticeably cheaper to heat.
| Water depth | Gallons | Liters |
|---|---|---|
| 3 to 5 ft floor | 8,618 | 32,621 |
| 3 to 6 ft floor | 9,695 | 36,699 |
| 4 ft all over | 8,618 | 32,621 |
Surface area is 288 sq ft, and each extra inch of water adds about 180 gallons, so a level check is worth doing.
