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

Door Kilograms (kg)

Required number input.

Rated Kilograms Per Hinge (kg)

Required number input.

Mass-only arithmetic lower bound from door mass and a per-hinge rating for the same installation. It is not a safe hinge specification: door width, hinge spacing, and load distribution must be checked separately. 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]

Hinge Count

The resulting hinge 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.

• Sockelfuss Anzahl

  Minimum number of plinth feet for two straight front and rear rows under a cabinet, using a chosen maximum spacing; excludes load-rating checks.

• Edge Banding Trim Allowance

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

• Door Frame Width With Gaps

  Compute door frame inner width and total side gap from the leaf width and per-side clearance.
