How it works.
Plain maths you can check yourself.
- Wall areaTwice the length plus the width, times the wall height.
- OpeningsDoors and windows you measure are taken off the total.
- CoverageTaken from the paint maker's tin for the paint you are buying, so the answer matches your paint.
- LitresArea to paint, times the number of coats, divided by the coverage. Round up to the next tin size.
