Paint calculator

The first step in calculating how much paint you need for a project is to work out the size of the surface area that needs covering. Our handy calculator below allows you to enter the dimensions of your walls to calculate the total surface area. Browse our range of paint products and your total surface area will be displayed at the bottom of your browser. The product pages will display the coverage of your chosen paint so you can work out how much you need.
