Spring Pitch Calculator

Spring Pitch Calculator calculator can be used to calculate the pitch of a spring based on the number of coils, mean diameter, and free length.

Input Parameters

Calculation Results

Calculation Formula

Pitch (P) = (Free Length - (Number of Coils - 1) * Wire Diameter) / Number of Coils

Where:
P = Pitch of the spring (mm)
Free Length = Total length of the spring when no force is applied (mm)
Number of Coils = Total number of coils in the spring
Wire Diameter = Diameter of the wire used to make the spring (mm)

How to Use the Spring Pitch Calculator

  1. Enter the number of coils in the spring.
  2. Enter the mean diameter of the spring in millimeters.
  3. Enter the free length of the spring in millimeters.
  4. Click the "Calculate" button to compute the pitch of the spring.
  5. The pitch of the spring will be displayed in millimeters.

Working Principle

The pitch of a spring is the distance between corresponding points on adjacent coils. It is calculated using the formula:

Pitch (P) = (Free Length - (Number of Coils - 1) * Wire Diameter) / Number of Coils

This formula assumes that the wire diameter is known. If the wire diameter is not provided, it is estimated based on the mean diameter and the number of coils.
