How To Determine Size Of Garage Door Spring

Garage door springs are an essential part of the garage door system, as they help to lift and lower the door with ease. If you have a garage door that is not working properly, it is important to check the springs to see if they need to be replaced. One of the most important factors to consider when replacing garage door springs is the size of the springs. The wrong size springs can cause the door to be difficult to lift, or they can even cause the door to fall. To ensure that you get the right size springs, it is important to know how to determine the size of your garage door springs.

There are two main types of garage door springs: torsion springs and extension springs. Torsion springs are mounted on a shaft above the door, while extension springs are attached to the sides of the door. To determine the size of your garage door springs, you will need to know the following information:

The weight of the garage door
The height of the garage door
The type of garage door springs you have

Once you have this information, you can use the following formula to determine the size of your garage door springs:

Spring Size = (Door Weight * Door Height) / Spring Constant

The spring constant is a number that is specific to the type of garage door springs you have. You can find the spring constant for your springs in the manufacturer's specifications. Once you have calculated the spring size, you can purchase new springs that are the correct size for your garage door.

Here are some additional tips for determining the size of your garage door springs:

If you are not sure about the weight of your garage door, you can weigh it using a bathroom scale. Simply place the scale under the door and lift the door until it is fully open. The weight of the door will be displayed on the scale.
If you are not sure about the height of your garage door, you can measure it from the ground to the top of the door.
If you are not sure about the type of garage door springs you have, you can look at the springs themselves. Torsion springs are usually mounted on a shaft above the door, while extension springs are attached to the sides of the door.

By following these tips, you can easily determine the size of your garage door springs and purchase new springs that are the correct size for your door.
