Drywall Sheet Sizes (Dimensions, Weight & Price)
Part of Interior & Finishes
Quick answer
Standard drywall is 4 feet wide and 8, 10 or 12 feet long. The 4×8 sheet (32 ft²) is most common, weighs about 50 lb in 1/2 inch, and costs roughly $12–$18 for standard board.
Drywall sheets are always 4 feet wide; the length is what varies. Longer sheets cover more with fewer seams to tape, but they're heavier and harder to maneuver up stairs and around corners.
Standard sheet sizes
| Size | Area | 1/2" weight (approx.) |
|---|---|---|
| 4 × 8 ft | 32 ft² | ~50 lb |
| 4 × 9 ft | 36 ft² | ~57 lb |
| 4 × 10 ft | 40 ft² | ~63 lb |
| 4 × 12 ft | 48 ft² | ~75 lb |
What a sheet costs
| Board | Price per 4×8 sheet |
|---|---|
| 1/2" standard | $12–$18 |
| 5/8" Type X (fire) | $15–$22 |
| Moisture-resistant | $15–$20 |
| Mold-resistant | $18–$28 |
5/8 inch board weighs noticeably more (70–80 lb for a 4×8), which is why 1/2 inch is the default for walls hung by hand. Lightweight 1/2 inch options cut that to around 40 lb.
FAQs
What is the most common drywall size?
The 4×8 foot sheet is by far the most common because one person can handle it. Pros often use 4×12 on long walls to cut down on seams.
