First, assess the size of the area that you’re painting. Grab a friend to help measure the width and height of walls with a metal tape measure and multiply these together to calculate the overall square feet measurement.
Subtract the space used by windows and doors using the same calculation method as above, and remove these from your overall square feet measurement.
Multiply your new total squarefeet measurement by the number of coats you’ll need – we recommend factoring in at least two coats. It's also worth including a little extra wall paint for touch ups.
Finally, divide this total figure by the f²/l number on your paint can (if you can’t see it on the can, have a look online at the product information section). This will give you the total litres of wall paint you need for your project.
Don’t forget, the type of paint will make a difference and so will the manufacturer. When you use higher quality wall paint, you’ll notice that you use less paint to get a great result. Less paint equals a happier atmosphere – and a beautiful finish for you.
