A 12 × 24 ft oval above-ground pool with 52 in walls holds about 6,490 US gallons (24,550 L) when filled to 46 in of water, about 6 in below the top rail. Volume depends on the water depth, not the wall height, so measure your water and check the table.
| Water depth | US gallons | Litres |
|---|---|---|
| 44 in of water | 6,200 gal | 23,490 L |
| 46 in of water | 6,490 gal | 24,550 L |
| 48 in of water | 6,770 gal | 25,620 L |
Formula: 24 × 12 × 3.83 ft × 5.87 = 6,486 gal. Oval pools with straight sides hold a little more than a true ellipse; use the manufacturer’s figure if it differs.

Manufacturer capacities are usually given at a stated fill level, and liners stretch. To confirm your real volume, add a known amount of salt or stabilizer and see how much the test reading moves: the volume that explains that change is your pool.
