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

Mortise depth (mm)

Required number input.

End clearance (mm)

Required number input.

Find maximum tenon insertion length from measured mortise depth after reserving a nonnegative end clearance. 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]

Tenon insertion length (mm)

The resulting tenon insertion length 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.

• 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.

• Mortise Depth

  Specify mortise depth for a given tenon length plus a deliberate end-clearance allowance for glue or debris.

• Domino Routing Depth Calculator

  Compute the mortise depth for a centered Domino loose-tenon joint. Each workpiece normally receives half the nominal tenon length; verify the joiner's available depth-stop setting, especially for the 4 x 20 mm Domino.
