How Many Metal Studs Do I Need?
Quick Answer
6 studs + top and bottom track for a 3m wall
Based on: 600mm centres, 2.4m high wall. Studs at each end plus intermediate at 600mm spacing
How We Calculated This
- Wall length: 3m
- Stud spacing: 600mm centres
- Number of studs: (3000 ÷ 600) + 1 = 6 studs
- Top track: 1 × 3m length
- Bottom track: 1 × 3m length
Standard Metal Stud Sizes
- 48mm (C stud): Thin partitions, minimal sound insulation
- 70mm (C stud): Standard domestic partitions
- 92mm (C stud): Enhanced sound/fire performance
- 146mm (I stud): Shaft walls, deep service voids
Track Sizes
Floor and ceiling tracks (U channels) match the stud width. Standard lengths are 3m or 3.6m. Cut to wall length on site.
Additional Components
- Door studs: 2 extra studs per door opening (plus header track)
- Nogging (horizontal bracing): At 1200mm height for board joints
- Acoustic insulation: Mineral wool between studs, 50–100mm
- Resilient bars: For enhanced sound insulation (at 600mm centres horizontally)
Spacing Options
- 600mm centres: Standard for 12.5mm plasterboard
- 400mm centres: For heavier cladding or when extra rigidity is needed
