Work out how many studs you need for a wall, based on wall length, wall height and center spacing (on-center).
The calculator divides the wall length by the center spacing, rounds up, and adds one extra stud at each end:
Meters of stud timber is found by multiplying the number of studs by the wall height. Meters of plate is calculated as twice the wall length, since both the top and bottom plate run along the entire wall.
600 mm (16" is the closest imperial equivalent) is most common for interior walls in homes, and works well with standard panel widths like 1200 mm. Load-bearing walls can have 400 or 600 mm spacing depending on structural requirements.
Yes, openings for doors and windows require extra studs and often a header to stiffen the structure. This must be added on top of the calculated number in this calculator.
Both terms describe essentially the same build-up, with vertical studs between a top and bottom plate. "Timber frame" is often used for load-bearing exterior walls, while "stud wall" is often used for non-load-bearing interior walls.
