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

Biscuit size

Biscuit size: 0, 10, or 20.

Look up the standard joiner plunge depth for size 0, 10, and 20 compressed-wood biscuits. 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]

Slot depth (mm)

Required slot depth in millimeters.

• 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.

• Biscuit Size Lookup

  Look up the width, height, and thickness of a standard biscuit size.

• DIN 68901 Carcase Depth Lookup

  Look up the nominal DIN 68901 kitchen carcase depth for slim, standard, and deep classes; fronts are typically 50 mm deeper than the carcase.

• Clamex P Drilling Pattern

  Look up the P-System groove depth, 6 mm lever-access hole, and minimum butt-joint and miter material thicknesses for Clamex P-10 and P-14 connectors.
