Paint Calculator

Estimate paint volume from net area, number of coats, coverage and waste.

How it works

Estimate paint volume from net area, number of coats, coverage and waste.

Core method:
Paint = net area × coats ÷ coverage, then waste is applied. Cans are rounded up to the selected can size.
Before you use the result: Check project drawings, supplier data and site conditions before ordering materials.

Practical use

Enter dimensions from the latest drawings or verified site measurements. Adjust allowances and material properties to the supplier or specification you are actually using. Results update instantly as inputs change.

  • Keep units consistent with the source information.
  • Use project-specific densities, pack sizes and coverage rates where provided.
  • Round purchasing quantities to supplier packaging and delivery rules.
