Confused about how many coats you will need? Not sure how many tins to buy? Work out what you need beforehand with these simple steps to help you calculate the right requirements. First things first, grab yourself a tape measure…

Measure up

Start by measuring the maximum height and width of the wall you want to paint. Then multiply the two measurements together to get the overall square meterage. Do the same for your windows and doors and then subtract from your overall square meterage.

Number of coats

The quantity of paint you need will be determined by the amount of coats. We always recommend two coats of your chosen colourful top coat for even coverage. Multiply your final square meterage by two (that allows for 2 top coats)

Last bit of adding up  

Take the total number you just calculated, divide the number by the square metre per litre listed on your paint tin or in the online product information. And there you have it, you’ve worked out the amount of paint you need.

If you need more help, most paint manufacturers have online coverage calculators specific to their brand. This will help you get as accurate a number as possible.
