The maths

  1. Area = π × 5² = 78.5 sq ft
  2. Volume = 78.5 × 2.5 = 196 cu ft
  3. 196 cu ft × 7.48 gal per cu ft

= 1,470 US gallons

Real pools vary: water levels sit a few inches below the wall top, floors slope and corners are rounded. If your pool’s depth differs, adjust it in the volume calculator.
