Garage Door Springs and their Importance

Garage doors rely heavily on the Garage Door Springs to function properly, making it essential for homeowners to understand the role of the garage door spring. Although most homeowners believe the garage door opener is the key component, it’s the springs that do the heavy lifting. When the opener is activated, the springs to “unwind” and release energy to lift the door.

These springs carry the weight of the garage door, making it open and close. Without them, the opener would have to do all the work, leading to premature failure. Broken springs can make the door too heavy, causing the opener to overwork and potentially burn out. Checking the springs regularly is essential for their proper functioning.

Types and Sizes

Made of oil tempered or galvanized steel, garage door springs have a cycle rating depending on the quality and weight of the door. Most are rated for 10,000 to 15,000 cycles. A cycle is a full opening and closing of the Garage door. The springs store energy when the door is closed, which helps lift the door when opening.

The weight of the garage door determines the wire size needed for the springs. Heavier doors require stronger springs with a larger wire size. For instance, a standard 16×7 garage door typically weighs between 150 and 250 pounds. A smaller wire size may not be able to lift the door’s weight, leading to poor functionality. Wire sizes of .207, .225, .250, and .275 are available, with a larger wire size indicating a stronger spring.

The wire size of a garage door spring is typically measured in gauge, with larger numbers indicating a smaller wire diameter. The most common wire sizes for garage door springs are .207, .225, .250, and .262 gauge. These sizes correspond to different strength levels needed to lift various weights of garage doors.  For example, a .207 wire is generally used for lighter garage doors that weigh between 80 and 220 pounds. This size spring is not as strong as larger gauges and may not be sufficient for heavier doors. Whereas a .250 wire is typically used for garage doors that weigh between 160 and 350 pounds. This wire size is also suitable for larger 8×7 garage doors or smaller 16×7 garage doors.

Choosing the appropriate wire size is crucial for the performance of the garage door. A wire size that is too small may not be strong enough to lift the weight of the door, resulting in an improperly functioning door. A wire size that is too large, on the other hand, may be too strong, causing unnecessary wear and tear on the opener and other components of the door.  It is important to note that the appropriate wire size for a garage door spring may also depend on other factors, such as the height of the door.  A professional technician can help ensure that the appropriate wire size is selected for optimal performance.


If the spring is too weak, the opener will need to work harder to lift the door, and it may struggle to lift it at all. This puts a strain on the opener’s motor and other components, causing them to wear out faster than they should. The opener may also overheat, which can lead to electrical problems or even a fire.

On the other hand, if the spring is too strong, it can cause unnecessary wear and tear on the opener and other components of the door. This can lead to premature failure of these components, resulting in costly repairs.

A spring that is too weak may not be able to support the weight of the door, causing it to fall suddenly and potentially causing injury or damage. A spring that is too strong can also be dangerous. It may cause the door to move too quickly and unexpectedly.


Garage door springs play a vital role in the functioning of garage doors. Homeowners should choose the appropriate wire size and maintain and inspect the springs regularly to ensure optimal performance and prolong the door’s life. By understanding the function of the springs, homeowners can better care for their garage doors.
