Formula
Regular stud spaces = ceiling(wall length in inches / on-center spacing); base studs = spaces + 1.
About the Wall Stud Calculator
Estimate regular studs, end studs, opening-support studs, and total studs for a framed wall. This tool keeps the requested measurements separate and applies the named method instead of substituting an unrelated general estimate.
How the Wall Stud Calculator Works
The base layout is increased by user-entered corner and opening support studs, then waste is added and rounded up.
Formula
Regular stud spaces = ceiling(wall length in inches / on-center spacing); base studs = spaces + 1.
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.
Required Inputs
