Volume by water depth
| Water depth | US gallons | Litres |
|---|---|---|
| 44 in of water | 4,850 gal | 18,350 L |
| 46 in of water | 5,070 gal | 19,180 L |
| 48 in of water | 5,290 gal | 20,020 L |
Formula: 15 × 15 × 3.83 ft × 5.87 = 5,067 gal.
A 15 ft round above-ground pool with 52 in walls holds about 5,070 US gallons (19,180 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 5,000 gallons, salt and stabilizer. Or put 5,067 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 5,070 gallons at 46 in of water.
About 19,180 L at 46 in (117 cm) of water.
