Basically, you run a tape measure along the length of a spring, and take down the number of inches. Therefore, if your tape measure indicates that a torsion spring is 36 inches from one end to the other, that’s a 36-inch — or three foot — torsion spring.
How do I know what size torsion spring I need for my garage door?
Measure the circumference of the cable drum, and measure the height of the garage door in inches. Divide the height of the garage door by the cable drum circumference, then add one. This is the number of turns that are on your spring. For example, a 14′ high door is 168″ high.
What size garage door spring should I get?

Can I use a larger torsion spring on my garage door?

Does length matter for garage door torsion spring?
Replacing a too-big or too-small torsion spring with the right size will balance the door and make it safe again. The door will rise with less effort and remain safely in place. The garage door opener may also need to be replaced if it has been damaged by springs that are too big or too small.
Can I use a different size spring on my garage door?
When you add everything up, you have the exact weight once done; you can then use two different size springs if it yields optimal balance. If you are a homeowner and the technician used two different size springs, don’t be alarmed. What matters is that the garage door is balanced.
Why does my garage door have 2 different springs?
Doors with extension springs should always have two springs. The pair work together to provide a counterweight to the door. If one of your garage door springs breaks or is in poor condition, replace both springs. Replacing one spring just means the older spring will have to be replaced in a matter of time.
Should a double garage door have 2 springs?
As a rule of thumb, a single garage door takes one torsion spring. A double-wide garage door takes two springs. However, if you have an exceptionally heavy single door, you may need two torsion springs.
