Paint calculator
Estimate how many litres of paint you need.
How the calculation works
Litres = area × number of coats / coverage per litre, increased by your extra allowance.
A practical example
40 square metres, two coats and 10 square metres per litre require 8 litres. Add 10% for a total of 8.8 litres.
Important details
Enter net area excluding doors and windows. Use manufacturer coverage and round up to available tin sizes. Surface absorption affects actual usage.
