Use this workshop calculation to turn measured dimensions and the selected construction convention into a cut, spacing, fit, or material-planning value.

Total Run Meters (m)

Required number input.

Total Rise Meters (m)

Required number input.

Theoretical straight stair-stringer run length from total horizontal run and vertical rise, before end cuts or overhangs. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Stringer Meters (m)

The resulting stringer meters returned as a number.

• Nominal dimensions, kerf, moisture movement, hardware clearances, wall squareness, and manufacturer instructions can change the required shop dimension. Measure the actual assembly and test critical joints on scrap before cutting finished material.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Complement the calculated dimension with a physical story stick, dry fit, or full-size layout. Follow the hardware, coating, adhesive, or machine manufacturer's limits where they differ from a rule of thumb.

• Bevel Angle

  Bevel angle of a sloped cut from vertical rise and horizontal run in the same length unit; measured from the horizontal.

• Gate Diagonal Brace Length

  Find the straight corner-to-corner brace length of a rectangular gate frame; excludes joinery and end cuts.

• Stair Run Length Calculator

  Compute the total stair run in centimeters as the tread depth times the number of steps minus one.
