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

Flight width (cm)

Stair flight width in centimeters between 60 and 200.

Apply the stair landing rule that a landing must be at least as deep as the stair flight is wide. 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]

Landing length (cm)

Required landing length in centimeters, equal to the flight width.

• 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.

• Treppen Sicherheitsregel

  Compute the German stair safety-rule dimension as tread going plus riser height; this is a planning metric, not a structural or code check.

• Auszugsschienen Laenge

  Longest drawer-slide length that fits a measured cabinet interior depth after reserving a specified rear clearance; choose an available product size no longer than this result.

• Drawer Side Length Rule

  Compute the slim drawer side length by subtracting 54 millimeters from the front width.
