How do you measure a compression spring?

Using a caliper you will need to measure the following:

  • Wire Diameter
  • Outer Diameter
  • Free Length
  • Number of Coils

If you can, it would also be helpful to determine your coil spring wire type and material. You can also send a prototype spring to our engineers and they will be happy to do the calculations for you.
