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

Full-width cuts

Required integer input.

Measured blade kerf (mm)

Required number input.

Calculate total stock length removed by a known number of full-width saw cuts and blade kerf width. 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]

Total kerf loss (mm)

The resulting total kerf loss 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.

• Zinken Teilung Breite Gleich Dicke

  Maximum count of full-width equal fingers when target finger width equals stock thickness, plus unused length.

• Edge Banding Trim Allowance

  Calculate total edge-banding width to trim and the equal amount per face when strip is centered on a panel.

• Planing Pass Depth Calculator

  Calculate the material removed per planing pass from the total depth and pass count.
