Free Stud Count calculator with clear step-by-step results.
Common studs are wall length over spacing plus one for the end, but openings and junctions add a great deal: each opening needs two trimmers and two cripples, and each corner or T-junction needs a pair. The linear timber figure converts stud count into what you actually order.
Common studs
Studs = ceil(wall length / spacing) + 1
Total studs
Total = common studs + openings x 4 + junctions x 2
Load-bearing wall framing, lintel sizing over openings and bracing requirements are governed by building codes. Structural walls should be designed or checked by a qualified professional.
Four hundred is standard for load-bearing walls and gives a stiffer surface for plasterboard. Six hundred is common for non-load-bearing partitions and saves timber, but needs thicker board.
They stiffen the wall, provide fixing for board edges, and are needed where heavy items will be hung. One row at mid-height is typical for a 2.4 m wall.
