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

Piece lengths (mm)

Required list input.

Summarize stored offcut pieces by count and total length in millimeters. 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]

Piece count

The resulting piece count returned as an integer.

Total length (mm)

The resulting total 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.

• Kantenanleimer Bedarf

  Total edge-banding length from count of identical panels and number and length of edges banded on each panel.

• Clamp Count

  Round up clamp count from total target clamping force and the usable force rating per clamp at the actual setup.

• Crown Molding Length

  Total measured crown-molding runs and add a project-specific cut-and-waste allowance.
