Drywall Calculator for Garages
Estimate drywall sheets for a garage, including fire-rated board.
Garages often require fire-rated 5/8 in "Type X" drywall, especially on walls shared with the house. Add the wall and ceiling area, divide by 32 sq ft per sheet, and check local code for which surfaces must be rated.

How it's calculated
A standard 4×8 ft sheet covers 32 sq ft; a 4×12 ft sheet covers 48 sq ft. Sheets = round up (wall + ceiling area × (1 + waste) ÷ sq ft per sheet).
