Frequently asked questions

How many drywall sheets do I need?

Divide the wall area by the area of one sheet and round up. A standard sheet is 1.2 × 2.5 m (3 m²) or 4 × 8 ft (32 sq ft). Add about 10% for cuts around openings.

How many screws are needed per drywall sheet?

Roughly 30–35 screws per sheet, placed every 20–25 cm along the studs. Sheets on a ceiling or a second layer need slightly more.

How far apart should the studs be?

Vertical studs are usually placed every 40–60 cm. Use 40 cm for a ceiling or when you want a stiffer wall, and add perimeter track profiles at the floor and ceiling.

What thickness of drywall should I use?

Use 12.5 mm (1/2 in) sheets for walls and ceilings in most rooms. Thinner 9.5 mm sheets suit curved surfaces, and two layers improve sound insulation and fire resistance.
