How many gallons does a 24 foot by 24 foot by 4 foot pool hold?
About 14,351 US gallons of water.
go to www.extendaswim.com and use the pool volume calculator to find out the exact gallons A 24 foot round pool that is 52 inches deep will hold approximately 14,645 gallons of water if filled completely. If filled to a 90% capacity, as recommended by most swimming pool manufacturers, it will hold approximately 12,481 gallons.
The volume depends on the height. A one-foot deep pool six-feet in diameter would hold about 176 Imperial gallons (211 US gallons). Every extra foot high would hold the same amount again A pool two foot six inches deep would therefore hold 176 * 2.5 = 440 Imperial gallons or 211 * 2.5 = 528 US gallons.
