How to Use This Calculator
Use the field units shown below, then compare your result with the worked example. Check whether shared walls or end studs have already been counted in another run.
How the calculation works
Wall length is divided by stud spacing, then end/opening/corner studs and waste are added. Plate length is estimated separately.
What the result means
Openings, intersecting walls, backing, headers and engineered details can add material.
Count a simple wall run
A 16-foot run at 16-inch spacing gives ceil(16 × 12 ÷ 16) + 1 = 13 studs before extras. With zero opening extras and 10% waste, the tool rounds to 15 studs. Its three-plate basis produces 52.8 linear feet, rounded to 53.
Contractor tip: Check whether shared walls or end studs have already been counted in another run. Plate footage does not tell you which stock lengths will minimize joints and offcuts.
Verify the final quantity
The openings input is the number of EXTRA studs you want to allow, not the number of windows or doors. This simple run count does not design corners, intersections, headers, bracing or load-bearing work.
Good practice: Compare the calculated quantity with plans, specifications, product packaging and current field conditions before purchasing material.
