Taper Calculator

Find taper per foot and angle.

Large diameter

Small diameter

Length

Taper per foot (in/ft) 0

Half-angle (°) 0

Formula: TPF = (large − small) ÷ length × 12

Step-by-step with your numbers:

1. Values used:

2. Large diameter = 1

3. Small diameter = 1

4. Length = 1

6. Taper per foot = 0in/ft

7. Half-angle = 0°

Did we solve your problem today?

Find the taper (slope) of a conical part.

The math behind it

taper per foot = (large − small diameter) ÷ length × 12; half-angle = arctan(diff ÷ 2÷ length).

2→1.5 in over 6 in → 1.0 in/ft (≈4.8°).

Morse taper?

Morse tapers are close to 0.625 in/ft (~MT2).
