To work out how much paint is needed for your interior or exterior project use our paint calculator:
(Surface area / Spreading rate) x Number of coats = the litres of paint required
Quick steps to estimate paint litres from house
To get a rough idea of how much paint you will approximately need when you only have house plans to work from, use the following calculations
Look for the statement of area on the house plans e.g. 186m2
Divide this by
10 = litres of sealer for ceilings
5 = litres of 2 coats for ceilings
4 = litres of sealer for walls
2 = litres of 2 coats for walls
25 = litres of primer for trim/doors/frames
15 = litres of 2 coats for trim/doors/frames
Enter the square area (m2) of house plan below and press "Calculate"
You will need...
litres of sealer for ceilings
litres of 2 coats for ceilings
litres of sealer for walls
litres of 2 coats for walls
litres of primer for trim/doors/frames
litres of 2 coats for trim/doors/frames
This quick estimate works as a general guide for most houses, but extreme designs or colour palettes tailored to each room will need a more careful approach with each room calculated individually.
