How it works
Ceiling area is length times width. Multiply by the number of coats, add a little for spatter and edges, and divide by the coverage per gallon. Round up to whole gallons.
Textured ceilings soak up more paint than smooth ones, so use a lower coverage figure for texture.
Worked example
A ceiling 14 ft by 12 ft, which is 168 ft² of area, needs 2 gal of paint for 2 coats.
Questions
Is one coat enough for a ceiling?
Many ceilings need two coats for an even colour, especially when a dark paint covers a light one.
Does this count the walls?
No. It counts the ceiling only. Measure the walls on their own.
What about a fan or light fixtures?
Fixtures are small, so they are not taken off the area. The allowance for waste covers the extra work around them.
