Calculate the size of your pool easily by entering the dimensions into the Pool Size Calculator.

Pool Size Calculation Formula

Use the following formulas to calculate the volume of your pool based on its shape.

Rectangular Pool: Volume = Length × Width × Depth
Circular Pool: Volume = π × Radius² × Depth

Variables:

  • Volume is the total volume of water in the pool (m³)
  • Length is the length of the rectangular pool (m)
  • Width is the width of the rectangular pool (m)
  • Depth is the average depth of the pool (m)
  • Radius is the radius of the circular pool (m)

To calculate the volume, multiply the dimensions according to the formulas provided.

What is Pool Size Calculation?

Pool size calculation refers to determining the volume of a swimming pool based on its dimensions. This calculation helps in understanding how much water the pool can hold, which is crucial for maintenance, filling, and water treatment planning. Accurate pool size calculation ensures efficient resource use and better pool management.

How to Calculate Pool Size?

Follow these steps to calculate the pool size:


  1. First, measure the dimensions of your pool. For rectangular pools, measure the length, width, and average depth. For circular pools, measure the radius and average depth.
  2. Use the appropriate formula to calculate the volume:
    • Rectangular Pool: Volume = Length × Width × Depth
    • Circular Pool: Volume = π × Radius² × Depth
  3. Plug in the measurements to the formula.
  4. Calculate the volume in cubic meters (m³).
  5. Check your result using the Pool Size Calculator above for verification.
