The amount of water a swimming pool can hold varies significantly depending on its size and shape. Common residential swimming pools, however, typically hold tens of thousands of gallons.
Capacity of Common Pool Sizes
According to Water Pump Supply, the capacity of a swimming pool in US Gallons is directly related to its dimensions. For some common pool sizes, the capacities are as follows:

| 20 ft x 40 ft | 30,000 |
| 20 ft x 44 ft | 33,000 |

These figures, sourced from store.waterpumpsupply.com, illustrate that typical backyard swimming pools are designed to contain substantial volumes of water, ranging from over 24,000 to nearly 40,000 US gallons for the sizes listed. The exact capacity of any specific pool would depend precisely on its dimensions (length, width, and average depth).
