Stud
A stud is a vertical framing member in a wall, spaced along a track or plate, to which sheathing and boards are fixed; it may be timber or steel.

What stud means
A stud is a slender vertical member in wall framing. Studs sit between a bottom plate or track and a top plate or track at regular spacing, and provide the fixing surface for boards and sheathing, and room for insulation and services.
They can be timber or formed steel, such as the C-shaped sections in cold-formed steel systems.
A plain example
In a steel framed wall, a C-section stud slots into U-shaped track at floor and ceiling, and screws hold them together. Extra studs are added at corners and openings. The size, thickness and spacing come from the design; any value in a catalogue should be confirmed with the manufacturer and engineer.
Why it matters
Studs may be part of a load-bearing wall or a non-load-bearing partition. The same word covers very different duties, so the role matters more than the name. Studs are also the main item in a material takeoff for framing.
Common confusion
A stud is a component, not a wall type, and a wall’s role cannot be read from the stud alone. In timber and steel the term is the same, but the products, fixings and design standards differ. Light-gauge steel studs follow product standards and engineered design.
Practical checklist
When specifying or ordering studs, include the details that identify exactly what you need.
- Material, section depth and thickness, and the coating or treatment.
- Length, spacing and where reinforcement is needed at openings.
- Matching track or plate and the fasteners to join them.
- Whether the wall is load-bearing, which needs an engineer’s design.
- Fire, acoustic and moisture requirements from the project specification.

Do studs only come in timber?
No. They are also made from formed steel and other materials.
What does stud spacing depend on?
Loads, materials and design requirements, set by the engineer or the applicable code.
