Paint Calculator
Calculate wall paint needed in liters from room size minus doors and windows.
—
How to use
- Enter the room length, width and height.
- Enter the number and size of doors and windows — this area will be subtracted.
- Enter the number of coats and the paint coverage (written on the paint box).
- Paint and primer will show in liters.
Note: Coverage depends on paint quality and how much the wall absorbs — old or raw walls take more paint. Rates change — verify with the official source before relying on this.
