Calculators
Paint quantity calculator
Estimate litres of paint from area, coats and the coverage on your paint can, with optional deductions and container sizes.
Enter the coverage stated on your paint can for one coat. This estimate does not guarantee actual coverage: surface absorption, texture and application affect consumption.
Your answer will appear here.
Help and method
Subtract excluded area from total area, then multiply by coats and divide by coverage per litre. Multiply by (1 + waste percentage / 100). If a container size is supplied, round the container count up to a whole number; purchased litres equal that count times container size. Limits: area 0.000001–1,000,000 m²; coats 1–100 whole numbers; coverage 0.000001–1,000,000 m²/L; container size 0.000001–1,000,000 L; extra allowance 0–100%. Results up to 1,000,000,000 L and containers. Nonzero inputs must be at least 0.000001.
