Spring Pitch Calculator


Calculating the spring pitch is crucial in various engineering applications, especially when designing springs for mechanical systems. The spring pitch calculator simplifies this process by providing an accurate and efficient way to determine the distance between adjacent coil centers. In this article, we’ll guide you through using a simple and effective calculator to find the spring pitch effortlessly.

How to Use:

To use the spring pitch calculator, follow these steps:

  1. Enter the values for wire diameter (D) and the number of active coils (N) in the designated input fields.
  2. Click the “Calculate” button to initiate the calculation.
  3. The result will be displayed, showcasing the calculated spring pitch.


The formula for calculating the spring pitch (P) is as follows:


  • P is the spring pitch,
  • W is the mean coil diameter,
  • D is the wire diameter, and
  • N is the number of active coils.

Example Solve:

Suppose you have a spring with a wire diameter (D) of 0.5 inches, a mean coil diameter (W) of 2 inches, and 10 active coils (N). Using the formula:

The spring pitch (P) is calculated to be 0.25 inches.


Q1: Can I use this calculator for all types of springs?

A1: Yes, this calculator is applicable to various types of springs, including compression, extension, and torsion springs.

Q2: What units should I use for input values?

A2: Ensure consistent units, whether inches or millimeters, for wire diameter, mean coil diameter, and the resulting spring pitch.


Designing springs becomes more efficient with the spring pitch calculator. By understanding the formula and utilizing the provided HTML and JavaScript code, engineers can quickly determine the spring pitch for optimal performance in their mechanical systems.
