Volume by water depth
| Water depth | US gallons | Litres |
|---|---|---|
| 44 in of water | 3,100 gal | 11,740 L |
| 46 in of water | 3,240 gal | 12,280 L |
| 48 in of water | 3,380 gal | 12,810 L |
Formula: 12 × 12 × 3.83 ft × 5.87 = 3,243 gal.
A 12 ft round above-ground pool with 52 in walls holds about 3,240 US gallons (12,280 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.

Full dose tables for a pool this size: liquid chlorine for 2,000 gallons, salt and stabilizer. Or put 3,243 gallons straight into the pool chemical calculator.
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.
About 3,240 gallons at 46 in of water.
About 12,280 L at 46 in (117 cm) of water.
