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

Standoff distance (mm)

Required number input.

Full fan angle (°)

Required number input.

Estimate spray fan width on a flat surface from standoff distance and full included fan angle, ignoring edge feathering. 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]

Geometric fan width (mm)

The resulting geometric fan width 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.

• Edge Banding Trim Allowance

  Calculate total edge-banding width to trim and the equal amount per face when strip is centered on a panel.

• Kanten Anleimer Ueberstand 1mm Fraesen

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

• 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.
