Stud Wall Load Calculator
Load per stud and a crushing/buckling sanity check for light-frame walls.
Concentrated loads (girder bearings, window kings) need built-up posts — the wall formula only covers the uniform story. Sheathing braces the weak axis; unsheathed studs lose half their capacity.
Formula
Stud Wall Load Calculator is a free stud wall load for structural engineers, fabricators and site engineers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Stud Wall Load Calculator
Load per stud and a crushing/buckling sanity check for light-frame walls. The calculation implements P_stud = w × spacing (NDS / CWC light-frame design). Concentrated loads (girder bearings, window kings) need built-up posts — the wall formula only covers the uniform story. Sheathing braces the weak axis; unsheathed studs lose half their capacity.
How to use Stud Wall Load Calculator
- 1Enter Roof/floor load on wall in kN/m.
- 2Enter Stud spacing in mm.

Frequently asked questions
What formula does the Stud Wall Load Calculator use?+
It computes P_stud = w × spacing, per NDS / CWC light-frame design. The formula is displayed under the result.
What should I keep in mind when using this calculator?+
Concentrated loads (girder bearings, window kings) need built-up posts — the wall formula only covers the uniform story. Sheathing braces the weak axis; unsheathed studs lose half their capacity.
Can I use this for real structural design?+
It implements the exact textbook/code formula cited below the result and is ideal for sizing, checking and learning. Final designs should be verified by a qualified engineer against the full code with all load cases.
Is the Stud Wall Load Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
