Average Depth = Deep End (feet) + Shallow End (feet) divide by 2 Rectangular / Square Pool: Length (feet) x Width (feet) x Average Depth x 7.5 = Total gallons Circular Pool: Diameter x 2 x Average Depth x 7.5 = Total gallons Oval Pool: Max Length (feet) x Max Width (feet) x Average Depth x 7.5 = Total gallons Kidney Shaped Pool: Width of Shallow End (feet) + Width of Deep End (feet) x Length of Pool x 0.45 x Average Depth x 7.5 = Total gallons Free Form Pool: Max Length (feet) x Max Width (feet) x Average Depth x 7.5 = Total gallons
