If you’re wondering how much paint you need for your next project, you’ve come to the right place. I’ve created this handy paint calculator so you can calculate how much paint you’ll need to purchase.
You can use the calculator to find out how much paint you need to paint your walls, skirting boards, exterior walls, or anything else you’re planning to paint.
Simply input the dimensions of the substrate you’ll be painting, the expected coverage of the paint you’ll be using, how many coats you need, and any dimensions you want to exclude (for example, any doors, windows or plug sockets).
The calculator will then give a value of how many litres of paint you’ll need.
Of course, this is just an estimation and thus I’d always recommend buying a little bit extra just in case.
