How much paint for a 10 × 12 room?
Estimate paint for a 10 by 12 room after confirming units, height, openings, coats and the coverage printed on the selected paint.
Measure every surface
Confirm whether 10 × 12 is feet or metres, then measure wall height. Add the ceiling only when it will be painted.
Subtract openings
Subtract measured door and window area from the gross wall and ceiling area.
Use product coverage and coats
Enter the coverage from the paint data sheet for the surface and application method, then apply the planned number of coats and visible wastage.
