Angled Plank / Miter Calculator
Angled Plank / Miter Calculator: calculate cut length with consistent units and explicit assumptions.
Inputs
mm
°
Results
- Cut face length
- 141.421356 mm
- Long-to-short offset
- 100 mm
Formula
Cut length = width ÷ cos(angle)
Offset = width × tan(angle)
Assumptions & limits
- Angle is measured from a square cut, not from the plank edge. Saw kerf excluded.
Worked example
For the example inputs: Cut face length = 141.4214 mm; Long-to-short offset = 100 mm.
Cut length = width ÷ cos(angle)
