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

Edge distance (mm)

Distance from the door edge to the center of the hinge cup in millimeters.

Compute the minimum stile width for a 35 mm hinge cup opened to 155 degrees. 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]

Cup diameter (mm)

Standard hinge cup bore diameter in millimeters.

Opening angle (°)

Hinge opening angle in degrees.

Minimum stile width (mm)

Minimum stile width in millimeters.

• 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.

• 110 Degree Hinge Cup Pattern

  Compute the minimum door stile width for a 110 degree overlay hinge cup from the cup edge distance.

• Clamex P Drilling Pattern

  Look up the P-System groove depth, 6 mm lever-access hole, and minimum butt-joint and miter material thicknesses for Clamex P-10 and P-14 connectors.

• Cleat Width Rule Calculator

  Compute the cleat width as twice the panel thickness with a 30 mm minimum.
