Helpful answers

Room paint estimator FAQs.

Quick guidance for using this tool well and understanding the result before you act on it.

How do I estimate paint for a room?

Measure the wall area, subtract large openings if needed, choose the number of coats, and compare the total with the paint coverage on the tin.

Should I allow extra paint?

Yes. A small allowance helps with touch-ups, uneven surfaces, and differences between real coverage and the figure on the tin.

Does ceiling paint count separately?

Usually yes. Ceilings often use a different finish, so estimate that area separately if you plan to paint it.
