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

First Center Millimeters (mm)

Required number input.

Last Usable Millimeters (mm)

Required number input.

Number of 32 mm-spaced hole centers that fit from a first center through a maximum usable end position, inclusive. 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]

Hole Count

The resulting hole count returned as an integer.

• 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.

• Duebelabstand 32mm System

  Center position of a selected hole on a 32 mm cabinet-system row from its first center and zero-based hole index.

• Einlegeboden Bohrungen Anzahl Pro Hoehe

  Count shelf-pin holes on one vertical row between a first and last usable center, inclusive, at a chosen center spacing.

• Shelf Pin Hole Positions

  Generate shelf-pin hole center positions from a first offset, equal hole spacing, and number of holes along one line.
