Drywall calculator
Count everything for a drywall partition, a wall lining or a suspended ceiling on a metal frame: plasterboards, studs and tracks or ceiling profiles with hangers and crabs, screws, joint tape and filler. Board and profile sizes are the ones sold in your region.

Consumption is the average from the «United Kingdom, Ireland, Australia and New Zealand» preset. Check it against your manufacturer's pack.
The calculator gives an estimate by the usual norms. Consumption depends on the product and the surface: check the manufacturer’s data before you buy.
How it’s calculated
- 1
Board area = length × height × number of sides × number of layers.
- 2
Boards = board area ÷ area of one board, plus a 10 % reserve, rounded up.
- 3
Studs = length ÷ stud spacing, rounded up, plus one; a stud taller than one profile is made of two.
- 4
Tracks run along the floor and the ceiling: 2 × length ÷ profile length.
- 5
Screws, tape and filler are counted per square metre: screws for every layer, tape and filler for the visible layer.

How many plasterboards for a partition?
A 4 × 2.7 m partition boarded on both sides has 21.6 m² of board. With 1.2 × 2.5 m boards (3 m² each) that is 7.2 boards, 8 with the reserve. A second layer doubles the boards and the screws, but not the tape and filler.
How many studs and tracks?
Studs stand every 600 mm (or the region’s spacing) plus one at the end: a 4 m partition needs 8 studs. The floor and ceiling tracks together are twice the length — 8 m, three 3 m profiles.
Questions
What is the difference between a partition and a lining?
A partition is boarded on both sides of its own frame; a lining covers an existing wall from one side. The calculator counts boards for one or two sides.
Why are screws counted for every layer?
Each layer of boards is fixed to the frame with its own screws, so two layers need twice as many.
Does the calculator include openings?
No, it counts a solid partition. A door opening reduces the boards a little and adds two studs around it — the reserve usually covers that.
