Do not fret! If you don’t have the measurements of the space you’re painting to hand, but you need to purchase that paint, we’ve put together a handy paint estimator.
Enough for a small patch on a wall.
A 750ml tin is perfect for a door or the skirting in a small room.
A 1 litre tin will be ideal to paint a 2.5m interior wall.
Around 2.5 litres would cover all walls in a 2m x 2m or equivalent room.
You’ll need about 5 litres to cover all walls in a 4m x 4m or equivalent room .
Psssst! Bought too much paint? If you haven’t used our paint calculator in the past and ended up with some leftover paint, rather than let it stack up in your shed, you could donate it to Community RePaint. It’s a paint recycling scheme sponsored by XPLOIT DESIGN PAINT and it collects and redistributes paint to improve lives within communities. Interested? You can find a participating centre near you at
