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

Workpiece Width Millimeters (mm)

Required number input.

Side Margin Millimeters (mm)

Required number input.

Minimum vise jaw width needed to cover a workpiece plus equal clamping margins on both sides. 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]

Jaw Width Millimeters (mm)

The resulting jaw width millimeters 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.

• Picture Frame Rabbet Width

  Find equal artwork overlap on both sides from artwork plus fit allowance versus the visible frame aperture.

• Kanten Anleimer Ueberstand 1mm Fraesen

  Edge-banding width needed for a panel thickness with 1 mm trimming overhang on both faces.

• 4-Inch Baluster Spacing

  Count equal-width balusters and calculate equal clear gaps, including both end gaps, so none exceeds a four-inch maximum.
