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

Glass and backing stack (mm)

Required number input.

Bedding clearance (mm)

Required number input.

Size a glazing-frame rabbet from measured glass-and-backing stack thickness plus bedding 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]

Frame rabbet depth (mm)

The resulting frame rabbet depth 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.

• Lichtausschnitt Tuer Glas Groesse

  Calculate rectangular glass cut size from a measured door opening and equal edge clearance on all sides; glazing bite is not included.

• Mortise Width

  Size mortise width to receive a measured tenon thickness plus chosen side-to-side fit clearance.

• 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.
