Finding the Length of a Spring

For a broken spring lay the pieces as best you can to get the overall length or count the number of full coils and multiply by the wire size.*

Note: The final size of the spring you receive may vary by +1/-1 the width of a coil.

Finding the Wire Size of Torsion Springs

If you don’t have a spring wire gauge or a pocket wire gauge, you can always use this trusted math formula to find the wire size of the torsion spring. To get started count 10 or 20 coils on the torsion spring. Measure the coils with your tape measure. Take the measurement and then divide by the number of coils you counted (10 or 20). The answer to the equation would be the wire size for the spring you just measured. Measure to the nearest 1/16 of an inch.

10 COIL EXAMPLE:

10 Coils = 2-7/8 (2.875) Inches

2.875 / 10 = 0.289 Wire Size

20 COIL EXAMPLE:

20 Coils = 5 Inches

5 / 20 = .250 Wire Size

You can also use the Spring Wire Chart below to convert the length of coils into the wire size without doing the math.

Finding the Inner Diameter (ID) of a Torsion Spring

With a tape measure or caliber, measure from inside spring coil to inside spring coil. The resulting measurement is the diameter of the spring. Measurements should be completed in inches and measured to 1/16” for accuracy.
