Understanding the Taper Degree Calculator
A taper in machining and woodworking refers to a gradual change in diameter or width along the length of a workpiece. Calculating the taper degree is essential for ensuring accuracy when cutting or grinding parts like spindles, tool shanks, and sockets. Our Taper Degree Calculator simplifies this complex trigonometric calculation, providing you with the taper angle and the taper per foot (TPF) instantly.
This calculator is a vital tool for machinists, engineers, and hobbyists who need precise measurements for designing and manufacturing tapered components.

Formula for Taper Angle (α)
The taper angle is the angle of the slope relative to the centerline. It is calculated using the following trigonometric relationship:
- D = Large Diameter
- d = Small Diameter
- L = Length of Taper
Formula for Taper Per Foot (TPF)
Taper per foot (TPF) is a standard unit in machining that expresses the change in diameter over a one-foot (12-inch) length. The formula is:
Note: Ensure D, d, and L are in the same unit (e.g., inches) for TPF. The calculator handles conversions for you.
How to Use the Taper Degree Calculator
- Select Units: Choose whether your measurements (D, d, L) are in Inches or Millimeters.
- Enter Large Diameter (D): Input the measurement for the larger end of the tapered section.
- Enter Small Diameter (d): Input the measurement for the smaller end of the tapered section.
- Enter Length of Taper (L): Input the length over which the diameter changes.
- Click 'Calculate': The results will show the Taper Angle (α) in degrees and the Taper Per Foot (TPF).
Applications of Taper Calculations
Tapered components are integral to many mechanical systems:
- Machine Tooling: Morse Tapers and Brown & Sharpe Tapers are used to secure tools (like drills and reamers) to machine spindles.
- Fixturing: Taper pins are used to align and secure parts in assemblies.
- Piping and Plumbing: Tapered threads (like NPT) ensure a fluid-tight seal.
- Woodworking: Creating legs for furniture or shaping tool handles.
