How to Calculate Your pool Water Volume:

You can easily calculate the water volume in your pool as follows: –

Round Pools

To calculate the volume of a round pool, you can use the formula

Pool Volume = 3.14 x radius x radius x depth

  1. Measure the diameter of the pool in metres
  2. Half the diameter to give the radius of the pool
  3. Multiply 3.14 x radius x radius x pool depth


A 12′ (3.66 m) diameter round above ground pool with a depth of 0.8m

Diameter = 12′ x 0.305 = 3.66m

Radius = 3.66 / 2 = 1.83m

Volume = 3.14 x 1.83 x 1.83 x 0.8m = 8.4 m3

Rectangular Pools

Pool volume = length x width x depth


6m x 4m pool, 0.8 m deep = 6 x 4 x 0.8 = 19.2 m3

Maximum for Poolstyle Mini 7kw = 20m3 so this would be ideal!

Typical Pool Sizes and Volumes

12′ x 36″ Intex above Ground pool = 9.6 m3 – Poolstyle 6kw OK !

18′ x 9′ x 52″ Intex above Ground pool = 18.4 m3 – Poolstyle 8kw OK !

24′ x 12′ x 52″ Intex above Ground pool = 32.7 m3 – Poolstyle 16.5kw OK !

30′ x 16′ x 48″ Intex above Ground pool = 54 m3 – Poolstyle 25kw OK !
