Framing

Stud length between plates

ls=H−tb−tt
where
ls
stud length (mm)
H
overall height (mm)
tb
bottom plate thickness (mm)
tt
total top-plate thickness (mm)
Explain this equation

Gives the stud length between plates from the overall frame height.

H is the overall frame height in millimetres. tb is the thickness of the bottom plate. tt is the total thickness of everything at the top, such as a double top plate. ls is the stud length.

The frame height is made up of the bottom plate, the stud and the top plates stacked on one another. Subtracting the plates leaves the stud.

A 2400 mm frame with a 47 mm bottom plate and a 94 mm double top plate needs 2259 mm studs.

Watch out: allow separately for any head clearance or deflection gap that has been specified.

Deduct bottom and top plate stacks from an overall frame height.

Good to know

All values in mm. Allow for head clearance or deflection details separately where specified.
