Taper Calculator
Result
Taper Calculator Calculate taper per foot, taper angle, and half angle for machined or fabricated tapers. — free online calculator.
Formula
- Taper Calculator calculates its result from Length, D. It uses the formula TPF = (D − d) / length × 12; Half angle = atan(TPF / 24). Change any input to recalculate the result instantly.
- The main inputs are Length, D. Enter them in the units and format shown in the calculator.
- Keep measurements and project assumptions consistent before comparing or combining values.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Taper
- Length: 2
- D: 3
Using Length = 2, D = 3, the calculated result is 0.
