The maths

  1. Area = π × 12 × 6 = 226.2 sq ft
  2. Volume = 226.2 × 4 = 905 cu ft
  3. 905 cu ft × 7.48 gal per cu ft

= 6,770 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.
