How to Measure Spring Tension Calculator
Definition: Spring tension, in the context of an extension spring, is a measurement of the force it exerts.
Extension springs come preloaded, meaning they already store force between their coils before extending. This initial tension needs to be considered when calculating the spring's working loads. To accurately determine spring tension, you'll need to factor in both the spring rate and this additional initial tension.
Spring Tension Calculation
One way to calculate spring tension is by using our spring calculator, Spring Creator X which can provide values for initial tension, spring rate, and working loads. Alternatively, you can measure spring tension with a simple scale. Initial tension becomes exhausted when the extension spring's coils extend to the point where you can see light in between the coils.
Calculating Spring Rate This diagram illustrates how to calculate your spring's rate using values from your working loads and the initial tension. To determine the rate, subtract the initial tension from the load and then divide the result by the distance traveled from the length inside hooks to the total extended length.

Rate = (Load - Initial Tension) / Travel
Where:
- Rate (k) is the spring rate.
- Load is the applied force.
- Initial Tension (IT) is the force stored within the spring when at rest.
- Travel (T) is the distance extended from the length inside hooks to the total extended length (L).
Using Spring Creator X
Use Spring Creator X For a quick and accurate way to calculate spring tension, spring rate, and other important extension spring parameters, consider using Spring Creator X, a powerful tool for extension spring design and analysis. This software streamlines the process and ensures precise results. By inputting the relevant data, you can easily determine the spring's characteristics and suitability for your application.
Don't hesitate to leverage the benefits of Spring Creator X for all your spring measurement and design needs.
