How to measure garage door torsion spring

Standard Garage Door Torsion Spring:

At, we carry high-cycle, heavy-duty, and precision-focused garage door torsion springs for anyone looking to repair their garage door. Standard residential torsion springs are found on a shaft above the center of the garage door. These springs typically come in 1 3/4", 2" and 2 1/4" inside diameters.

To Properly Measure a Garage Door Torsion Spring:

Step #1 Determine the Wire Size.
Measure the length of 10 coils and then measure the length of 20 coils. Using the chart below, determine the wire size of your old springs.
(Example: 10 coils measure 2 1/2” and 20 coils measure 5” then the diameter of your spring is .250)

Step #2 Measure the inside diameter (ID) of the spring:
Measure the inside diameter of your spring with a tape measure or caliper. Most common inside diameters are 1 3/4", 2", 2 5/8", 3 3/4" and 6"

Step #3 Measure the length of the UNWOUND coils of your spring:
Do not measure the end caps (cones) of the springs. If your garage doors has left and right wound springs, measure both, as they may be different. If the spring is broken measure each piece and add the measurements together to get the length. If it is still in one piece it will need to be unwound and be completely relaxed to get the proper measurement.
Step#4 Determine Wind Direction
Look at the end of the spring to determine the wind direction. If the end of the spring points in the clockwise direction it is a left wound spring. If the end of the spring points in the counter-clockwise direction it is a right wound spring.
