Paint calculator

Use our calculator to work out how far you can expect different types of paint to go. It's important to remember that the result given is an estimated value, as coverage will ultimately depend on how thickly the paint is applied and how porous the surface is.


First, take your measurements in metres or use the converter below. You'll need to measure window and door dimensions so that these can be subtracted from the calculation.
