How to Calculate Ceiling Square Footage
Calculate exact square footage for ceiling paint, drywall, or architectural features.
In standard rectangular rooms, the ceiling square footage matches the floor square footage (Length x Width). However, vaulted or coffered ceilings require different calculation techniques.
The Standard Ceiling Model
Multiply the length of the room by the width for a flat ceiling calculation.

Vaulted Ceilings
If your ceiling is vaulted, the area is the sloped dimension (Pitch) multiplied by the room length. Use our Roof Pitch Area tool for vaulted spaces to avoid running short on drywall.
