What Size Garage Door Spring Do I Need?

Garage door springs are an essential component of any garage door system. They provide the tension needed to lift and lower the door, and they help to keep the door balanced. If you have a garage door that is not opening or closing properly, it is important to check the springs to make sure that they are the correct size and that they are in good condition.

There are two main types of garage door springs: extension springs and torsion springs. Extension springs are mounted on the sides of the door, and they stretch when the door is opened. Torsion springs are mounted on a shaft above the door, and they twist when the door is opened.

The size of the garage door spring that you need will depend on the weight of your door and the type of spring that you are using. Extension springs are typically used for doors that weigh less than 100 pounds, while torsion springs are used for doors that weigh more than 100 pounds.

To determine the size of the garage door spring that you need, you will need to know the weight of your door. You can weigh your door by using a bathroom scale. Once you know the weight of your door, you can use the following chart to determine the size of the spring that you need.
