Pool Water Volume Calculator

How much water is in my swimming pool?

Below are the basic calculations to work out the volume of water in your swimming pool. These figures are useful when adding chemicals to your swimming pool.

If measured in feet:

Circular/Kidney shaped swimming pools

Length x Width x Average Depth x 4.54 = Pool volume in litres

Rectangular swimming pools

Length x Width x Average Depth x 6.25 = Pool volume in gallons

For all shapes measured in feet - Gallons x 4.54 = Volume in litres

If measured in metres:

Circular/Kidney shaped swimming pools

Length x Width x Average Depth x 1000 x 0.79 = Pool volume in litres

Rectangular swimming pools

Length x Width x Average Depth x 1000 = Pool volume in litres

For all shapes measured in feet - Gallons x 4.54 = Volume in litres
If measured in meters - 1 cubic meter = 1000 litres

Above Ground Swimming Pools

10' x 30" = 1000 gallons
12' x 32" = 1185 / 1520 gallons
15' x 36" = 2240 / 2780 gallons
18' x 42" = 4200 / 6076 gallons
