A ceiling is the floor area of the room, so measuring is easy. The texture decides how far each gallon goes.
How it works
Length × width gives ceiling area. Multiply by coats, then divide by a coverage figure set by the texture you pick.
Before you order
- Roll across the short dimension of the room so the lap marks are harder to see in window light.
- Flat ceiling paint hides roller marks and small flaws better than sheen.
- Popcorn ceilings soak up paint and can loosen when wet, so test a small area first.
Common questions
Does ceiling paint go further than wall paint?
Coverage is similar, around 250 to 400 sq ft per gallon depending on texture and porosity. Check your can.
Do I need two coats on a ceiling?
One coat can be fine for a same-color refresh. New drywall and stained ceilings usually want primer and two coats.
