How to Hang Drywall

Hanging drywall is a fundamental skill for any room addition, renovation, or repair. With the right technique and tools, a homeowner can hang walls and ceilings that finish as smoothly as professional work.

How many sheets do you need?

Room	Wall area	Ceiling	Total sheets (with 10% waste)
10 × 10 ft	320 sq ft	100 sq ft	16 sheets
12 × 12 ft	384 sq ft	144 sq ft	20 sheets
12 × 16 ft	448 sq ft	192 sq ft	23 sheets
20 × 20 ft	640 sq ft	400 sq ft	37 sheets

Wall area = perimeter × ceiling height. One 4×8 sheet = 32 sq ft.

What you’ll need

Materials:

Drywall sheets (1/2” for walls and ceilings; 5/8” type X for fire-rated)
1-1/4” coarse-thread drywall screws (for 1/2” drywall)
Paper tape or fiberglass mesh tape
All-purpose joint compound (pre-mixed)
Metal corner bead for outside corners
Primer (after finishing, before painting)

Tools:

T-square and utility knife for cutting
Drywall screw gun or drill with dimpler bit
Drywall lift (rental — essential for ceilings)
6-inch, 10-inch, and 12-inch taping knives
Pole sander with 120-grit screens

Drywall thickness guide

Application	Thickness	Notes
Standard walls	1/2 inch	Most common
Standard ceilings	1/2 inch	Use moisture-resistant in bathrooms
Fire-rated (garage/between floors)	5/8 inch Type X	Code required
Curved walls	1/4 inch	Bend in layers
Repair patches	1/4 or 3/8 inch	Match existing
Bathroom/wet areas	1/2 inch moisture-resistant	Or cement board for tile backer

Finishing levels (drywall levels 0–5)

The painting quality depends on the drywall finishing level:

Level 0 — bare drywall, no tape (not suitable for painting)
Level 1 — tape embedded in compound (fire-rated areas, above ceilings)
Level 2 — tape plus one skim coat (garage, storage areas)
Level 3 — tape + 2 coats, lightly sanded (behind texture)
Level 4 — tape + 3 coats, sanded smooth (most painted walls)
Level 5 — level 4 + skim coat (critical lighting, high gloss paint)

For standard painted rooms, Level 4 finish is the target. Level 5 is used in rooms with flat/matte paint under raking light (entryways, great rooms).

Frequently Asked Questions

How many sheets of drywall do I need for a room?

Divide total wall area by 32 sq ft (one 4×8 sheet). A 12×12 room with 8-ft ceilings has roughly 384 sq ft of walls — about 12 sheets, plus 5 sheets for the ceiling. Always add 10% for waste and cuts. Use the Drywall Calculator for exact counts.

What thickness drywall should I use?

1/2-inch drywall is standard for most walls and ceilings. 5/8-inch type X is required for fire-rated assemblies (attached garages, between floors in multi-family). 1/4-inch is used for curved walls. 3/8-inch is sometimes used for repair patches.

Should I hang drywall horizontally or vertically?

Horizontal (landscape) is preferred for walls — it minimizes butt joints, the hardest to finish smoothly. Vertical hanging is acceptable and easier for beginners. On 8-ft ceilings, horizontal sheets span 3 studs (16-in spacing) with fewer seams.

How far apart should drywall screws be?

On walls: 16 inches apart along field studs, 12 inches along edges and at corners. On ceilings: 12 inches along field joists, 8 inches along edges. Use 1-1/4 inch screws for 1/2-inch drywall on studs; 1-5/8 inch for thicker drywall.

How long does it take to hang drywall in a room?

An experienced crew hangs about 800–1,000 sq ft per day. A DIYer in an average 12×12 room should plan 6–10 hours for hanging (not including taping and finishing). Ceiling work takes about twice as long as walls and is much harder.
