Stud Partition Calculator
Enter the partition length, height and stud spacing to calculate the number of vertical studs, top-and-bottom track length and the plasterboard sheets (both faces) for light-gauge steel stud partitions.
Input Data
Results
At a glance:Light-gauge steel partition: vertical studs run along the length at a centre spacing; count = ⌊length×1000÷spacing⌋ + 1. Head and sill tracks run one each, total length = 2×length. Both faces are clad with plasterboard, total board area = wall area×2; a standard board is 1.2×2.4 m (2.88 m²), sheets = total board area ÷ 2.88 × (1 + waste%), rounded up. A 600 mm stud spacing matches a 1.2 m board width and reduces cutting.
Formula
Area = length × height
Stud count = ⌊length×1000/spacing⌋ + 1
Track = 2 × length
Boards = area×2 / 2.88 × 1.1 (rounded up)
$$A = L H$$$$n_s = \left\lfloor \frac{L\cdot1000}{s} \right\rfloor + 1$$$$T = 2L$$$$N_b = \left\lceil \frac{2A}{2.88}\cdot1.1 \right\rceil$$How to Use
- Enter the partition length and height.
- Enter the stud spacing (commonly 600 mm).
- The tool outputs area, stud count, track length and board sheets.
Case Studies
Office partition
5×3 m, spacing 600 mm.
Area 15 m²; 10 studs; track 10 m; about 12 boards.
Home divider
4×2.8 m, spacing 600 mm.
Area 11.2 m²; 8 studs; track 8 m; about 9 boards.
FAQ
How to choose stud spacing?
600 mm matches a 1.2 m board width so the board edge lands on a stud; too wide weakens stiffness.
Why double-face boards?
Both sides of a partition must be boarded to form the wall and give sound insulation, so area×2; waste covers cutting and door openings.
