Swimming Pool Volume (Gallons & Liters) & Free Chlorine Dosing Calculator: inputs, method, and how to read the result

Calculate pool volume (Length × Width × Avg Depth × 7.48052 gal/ft³) and chlorine dosing.

Choose inputs for the case you are checking

The defaults are illustrative. Replace them with values for your case and keep the units shown beside each field.

  • Pool Length Feet: Pool length in feet.
  • Pool Width Feet: Pool width in feet.
  • Shallow End Depth Feet: Shallow-end water depth in feet.
  • Deep End Depth Feet: Deep-end water depth in feet.

What the calculation includes

With the default values shown, Swimming Pool Water Volume is 22,022.65 gallons. The calculation follows Swimming Pool Volume & Chlorine Formula; the formula and variable definitions above show how the inputs combine.

One-input check: With the other defaults held constant, changing Pool Length Feet from 32 ft to 35 ft changes Swimming Pool Water Volume from 22,022.65 gallons to 24,087.27 gallons. This is a comparison inside the calculator's stated model, not a prediction.

Where to use caution

  • Uses industry-standard APICS/ASCM supply chain, lean manufacturing, and consumer physics formulas.
  • Actual commercial freight tariffs, marketplace commissions, and utility rates vary by carrier and contract.

Scope: Global Supply Chain, Business & Consumer Standard Check the assumptions and limitations against your situation before relying on the estimate.
