Common Residential Pool Sizes

The most common pool sizes vary based on shape, type, and intended use, but here are typical ranges in terms of gallons for residential in-ground pools:

1. Small Pools:

   • Gallons: 5,000 to 10,000
   • Size: 10' x 20' or 12' x 24'

2. Medium Pools:

   • Gallons: 10,000 to 20,000
   • Size: 14' x 28' or 16' x 32'

3. Large Pools:

   • Gallons: 20,000 to 30,000
   • Size: 18' x 36' or 20' x 40'

Most residential pools tend to fall within the 10,000 to 20,000 gallon range, especially for medium-sized family pools.
