Measuring Pool Capacity

Calculate Average Depth in feet:

Deep end depth (ft) + Shallow end depth (ft) = (ft)/2 = Average Depth (ft)

For a Rectangular or Square Pool:

Length (ft) x Width (ft) x Average Depth(ft) x 7.5 = Pool Capacity (gal)

For an Oval Pool:

Diameter (ft) x Long Diameter (ft) x Average Depth (ft) x 5.9 = Pool Capacity (gal)

For a Circular Pool:

Diameter (ft) x Diameter (ft) x Average Depth (ft) x 5.9 = Pool Capacity (gal)

For a Free Form Pool:

Surface (sq ft) x Average Depth (ft) x 7.5 = Pool Capacity (gal)
