Enter the larger diameter, smaller diameter, and length of taper into the calculator. The calculator will evaluate and display the total taper and taper angle.

Taper Angle Formula

The following equations are used to calculate the overall taper and taper angle.

T = (dl – ds) / L

TA = atan(0.5 x T)

  • Where T is the taper
  • dl is the larger diameter
  • ds is the smaller diameter
  • TA is the taper angle

Taper Definition

A taper is typically referred to as a section of a pipe that reduces in overall diameter over a certain length. That reduction in size is the taper, and the rate at which it reduces over the length is considered the taper angle.

Taper Example

How to calculate a taper?

  1. First, determine the larger diameter.

    Measure the larger diameter.

  2. Next, determine the smaller diameter.

    Measure the smaller diameter.

  3. Finally, calculate the taper.

    Calculate the taper and taper angle using the formulas above.
