What size torsion springs do I need for my garage door?

Torsion springs are undoubtedly one of the most crucial parts of a garage door. Usually, there are two torsion springs installed in every residential garage door. These can be found on the long metal bar on the top of the door.

As the garage door shuts, torsion springs store the tension on the coil and remain stretched. When the door opens, these springs relax and release the energy to lift the door smoothly. In other words, garage door torsion springs make the heavy garage door feel lightweight and easy to lift or shut with a garage door opener or even manually.

However, sooner or later, torsion springs (like any other mechanical component) wear out or break and need to be replaced. Even if only one of the two springs is worn out or damaged, you must always replace both springs to maintain the door’s balance.

But why is the balance important?

Well, a balanced door makes sure both sides go up and come down equally and not at different speeds. On the other hand, an unbalanced door makes more noise, causes the tracks to warp, works with a jerky motion, becomes unpredictable, and springs wear out even faster (within just a few years instead of 10 to 12 years of expected life).

Are you planning on replacing your garage door torsion springs, but are unsure about what size you need to buy?

If you are like most homeowners, the chances are that you are not familiar with all of your garage door components. This makes it more likely for you to buy parts that are not the right size for your garage door. So how do you ensure you buy the correct sized spring for your garage door?

At Integrity Garage Doors, we aim to provide homeowners in Dallas, TX, with the right-sized garage door components. When it comes to garage door springs, “one size fits all” is not applicable. However, with the following tips, you will be able to identify the right torsion springs for your garage door application.

1. Determine the wind direction

Look at the end of the spring points to determine the wind direction. Is it in the clockwise direction? It is left-wound. Is it in the counterclockwise direction? It is right-wound. You can also look at the color of the winding cones and cable drums of the springs to determine their wind direction — black indicates a left-wound spring while red indicates a right-wound spring.

2. Determine the overall length

Next, you have to measure the length of the unwound spring. You do not need to unwind the spring to determine how long it is; you can simply measure the spring’s length from the first coil on one end to the last coil on the other.

3. Determine the wire size

The wire size is the thickness of the wire used to make the spring. The only accurate way to measure torsion spring wire is to measure the length of 10 and 20 spring coils (in inches) that need to be replaced. You can then compare that measurement to the following torsion spring sizes to determine the correct wire size:

Length of 10 coils (in Inches)  Length of 20 Coils (in Inches) Wire Size
1 ¼ 2 ½ .125
1 ⅜ 2 ¾ .135
1 7/16 2 ⅞ .142
1 ½ 3 .148
1 9/16 3 ⅛ .156
1 ⅝ 3 ¼ .162
1 1/16 3 ⅜ .170
1 ¾ 3 ½ .177
1 ⅞ 3 ¾ .187
1 15/16 3 ⅞ .192

4. Determine the inside diameter

You can usually read markings on the winding and stationary cones to measure a torsion spring’s inside diameter. However, if there are no markings, you can simply measure the inside diameter with a ruler to the nearest 1/16.

Be cautious

When determining the right size of your garage door torsion springs, you must exercise caution.

Torsion springs remain under massive tension. If you are a DIYer or someone without proper knowledge and expertise in changing springs, you may land yourself in trouble. These springs have so much energy stored that they can pop out with force and cause serious injuries, even death if mishandled. In case the springs knock out while you are at it, the door may come down crashing, damage its working parts, break the overhead it is mounted to, or seriously injure anyone nearby.

The word of caution here is to let a professional garage door installer in Dallas, Texas, handle this task. They are qualified and experienced in replacing springs of the heaviest of garage doors.

A DIY garage door spring replacement is safe unless you are proficient in changing springs and have the necessary tools to ease the job in hand. If not, allow the pros to do what they are trained for!
