Wall stud calculator
Estimate studs, plates, and timber length for a framed wall. Calculations stay local in the browser and the assumptions are adjustable.
Project settings
Estimate studs, plates, and total timber length for a simple framed wall.
Quantity estimate only: adapt the values to the product, the site, and the applicable technical rules.

How does this tool work?
Estimate studs, plates, and total timber length for a simple framed wall. Adjust the assumptions to compare several scenarios before preparing a material order.
The timber wall framing calculator runs entirely in the browser from the dimensions and parameters you enter. The engine derives the base stud count from wall length and spacing, adds opening reinforcement and plate runs, then applies a waste allowance to the total timber length. Every result is recalculated when an input changes, so different assumptions can be compared before ordering. The calculation remains a quantity estimate: it does not verify building-code compliance, structural design, or product-specific installation requirements.
A regular-spacing count covers only the common studs; a door or window can require doubled studs, trimmers, headers and other reinforcement depending on the framing method. Use the project openings to adjust the baseline count.
How to use this tool
Describe the project
Enter the dimensions and parameters that match the real site.
Adjust assumptions
Match spacing, densities, stock sizes, and waste to the products you plan to use.
Check the quantity
Use the result to prepare an order, then verify it against the relevant technical requirements.
Use cases
Prepare an order
Turn project dimensions into a first timber wall framing quantity to compare with supplier pack sizes and stock lengths.
Compare assumptions
Change dimensions, spacing, density, or waste and immediately see how the required quantity changes.
Check a quotation
Use the intermediate results to verify the order of magnitude of a material quantity in a quote.
Tips and best practices
- Measure the actual site or finished support instead of relying only on drawings.
- Replace the suggested values with the manufacturer or supplier specifications.
- Use a waste allowance that reflects cuts, offcuts, overlaps, and site constraints.
Frequently asked questions
Does this replace structural or technical design?
No. The calculator estimates quantities from geometric inputs. Strength, sections, reinforcement design, spans, and code-required thicknesses must be checked separately.
Why include a waste allowance?
Waste covers some cuts, breakage, offcuts, overlaps, and measurement variation. The appropriate percentage depends on the material, layout, and site.
Can I order from the default values?
The defaults are examples only. Before ordering, replace them with the real dimensions and the technical specifications supplied for the product you will use.
