How much water is in a 24 ft round pool?
A 24-foot round pool is one of the most common above-ground pool sizes sold in the US. Using the standard round-pool formula -- diameter × diameter × average depth × 5.9 -- a 24 ft pool at a typical 48-inch (4 ft) depth holds about 13,594 gallons.
Depth is the main variable: many 24 ft above-ground pools are sold with wall heights of 48 in, 52 in, or 54 in, but the actual water level (and so the average depth used for this formula) is usually a few inches below the top of the wall. Measure your actual water depth with a tape measure for the most accurate number.
If your 24 ft pool has a deep end (uncommon for a round above-ground pool, but possible for a round in-ground pool), switch to the full Pool Volume Calculator and enter a shallow and deep depth instead of a single average.
Where these numbers come from
The formulas and default values in this calculator are based on:
- standard round-pool volume formula (diameter squared x average depth x 5.9) used across the pool industry
- typical above-ground pool water depths of 48-52 inches per manufacturer specification sheets
These are planning estimates. Test your actual water, follow product labels, and check your equipment manufacturer's guidance before you buy or dose chemicals.
Frequently asked questions
Is 13,594 gallons exact for every 24 ft round pool?
No -- it depends entirely on your actual water depth, which varies by pool model and how full you keep it. Use the calculator above with your own measured depth rather than assuming the example figure.
How many bags of salt does a 24 ft round pool need?
For a typical 13,500-14,000 gallon 24 ft pool starting from 0 ppm and targeting 3,200 ppm, that's roughly 360-375 lbs of salt, or about nine to ten 40 lb bags. Use the Pool Salt Calculator with your exact gallons for a precise number.
How long does it take to fill a 24 ft round pool?
At a typical garden hose flow of about 9 GPM, filling roughly 13,600 gallons takes around 25 hours of continuous running -- most owners fill over a day or two, or use two hoses at once to cut that time in half.
