How much does 5/8 drywall weigh?

Short answer

5/8 in Type X drywall weighs about 2.2 pounds per square foot, so a 4 × 8 sheet is about 70.4 pounds (31.9 kilograms) and a 4 × 12 about 106 pounds.

How to work it out

  1. 4×8: 32 sq ft × 2.2 lb/sq ft = 70.4 lb per sheet

Five-eighths board is the heavy one: fire-rated Type X for garages, ceilings and rated walls, and the stiff board many installers prefer on ceilings. USG and National Gypsum both list their 5/8 in Type X at 2.2 lb per sq ft.

  • Weight figure: USG Firecode X and National Gypsum Fire-Shield 5/8 in. Manufacturers give these as approximate, for design and shipping; damp board weighs more.
  • Fire-rated board is heavy. Plan two people per sheet, and a panel lift for ceilings.
  • Check what your vehicle and its tires are rated to carry before loading; yards deliver and stock board for a reason.

What 5/8 drywall weighs

At 70 lb a 4 × 8, a ceiling of 5/8 board is a job for a panel lift. The weight also matters for the framing and for what you carry up stairs: a two-car garage’s 28 sheets of 4 × 12 in 5/8 in Type X are about 3,000 lb.

Where 5/8 in Type X is required is set by your building code: under the IRC (R302.6) it goes on a garage ceiling with habitable rooms above, while the garage side of a shared wall needs at least 1/2 in gypsum board. Local codes amend this, so ask your building department. The 1/2 in weights are on how much does a 4x8 sheet of drywall weigh; the garage board count is on how many sheets of drywall for a 2 car garage.
