Enter your Pool Shape and dimensions — Length, Width, Diameter, Shallow End Depth, and Deep End Depth — and the Pool Volume Calculator will find your pool's total Volume, Average Depth, and Surface Area.

Knowing your pool's water volume is essential for calculating proper doses of chemicals like chlorine, shock treatments, and pH adjusters. It also helps determine heating costs and filtration requirements.
For pools with sloping bottoms, measure the shallow end depth and deep end depth, then add them together and divide by 2. For constant depth pools, simply use that depth measurement.
Rectangular pools use a multiplier of 7.5, while free-form or irregular shaped pools may require breaking the pool into sections and calculating each area separately for accuracy.
Always measure from the actual water depth, not the height of the pool wall. The water level is typically 6-8 inches below the pool coping or tile line.
Pool volume calculations are estimates based on geometric formulas. For irregular shapes or pools with complex features, the actual volume may vary by 5-10% from calculated values.
Yes, this calculator works for both in-ground and above-ground pools. Just select the appropriate shape and enter the dimensions of your above-ground pool.
For complex shapes, try to break your pool into simpler geometric sections and calculate each separately, then add the volumes together. For kidney shapes, use the free-form option with average dimensions.
