⬜Calculate Drywall
📐 كيف نحسب
The drywall calculator uses the following formula:
Standard Sheet: Drywall sheets are typically 1.2m × 2.5m (3.0 m² per sheet).
Fixings: Around 15 screws per m² spaced 25-30cm apart on the frame.
About this drywall calculator
This drywall (plasterboard) calculator estimates how many sheets, screws and metres of metal profile you need to board out a wall or ceiling. Enter the area to cover and, optionally, the room perimeter. The tool divides the area by the standard 1.2 × 2.5 m sheet (3.0 m²), rounds up to whole sheets, and works out screws at about 15 per m² plus the framing profile.
It is handy for stud partitions, dry-lined walls and suspended ceilings. Boarding both faces of a partition? Enter the combined area of both sides.
🧮 مثال الحساب
For a 30 m² wall with a 22 m perimeter:
- Sheet area = 1.2 × 2.5 = 3.0 m²
- Sheets = 30 ÷ 3.0 = 10 sheets
- Screws = 30 × 15 ≈ 450 screws
- Profile ≈ perimeter (22 m) + verticals (30 ÷ 0.6) ≈ 72 m
Round sheets up to whole boards — offcuts rarely cover a full extra panel.
💡 Practical tips
- Space studs at 600 mm centres so board edges land on a profile.
- Use moisture-resistant board in bathrooms and kitchens.
- Stagger board joints like brickwork to reduce cracking along seams.
- Allow extra jointing compound and tape for taping and filling the seams.
❓ الأسئلة الشائعة
A common plasterboard sheet is 1.2 m × 2.5 m, giving 3.0 m² per board. Other lengths exist, but the calculator uses this standard size.
Plan for about 15 screws per m², which is roughly 45 screws on a 3 m² sheet, spaced 25–30 cm apart along the studs.
A partition is boarded on both faces, so enter the combined area of both sides — for a 10 m² wall that means 20 m² of board.
The perimeter is optional. Adding it gives a more accurate metal profile estimate by including the edge tracks; without it, the tool falls back to a rough factor.
