Garage Door Torsion Spring Size Chart

Garage door torsion springs are crucial components that counterbalance the weight of the door, making it easier to lift and lower. Selecting the correct size torsion spring is essential for the proper functioning and safety of your garage door.

The size of a torsion spring is determined by several factors, including the door's weight, height, and width. The following chart provides a general guideline for selecting the appropriate torsion spring size based on door weight:

Door Weight (lbs)	Spring Wire Diameter (inches)	Spring Length (inches)
100-150	0.225	26-30
151-200	0.250	32-36
201-250	0.275	36-42
251-300	0.300	42-48
301-350	0.325	48-54
351-400	0.350	54-60
401-450	0.375	60-66
451-500	0.400	66-72

In addition to the weight of the door, the height and width of the door also influence the torsion spring size. Taller and wider doors require stronger torsion springs to effectively counterbalance their weight.

It is important to note that this chart is a general guideline only. The actual torsion spring size may vary slightly depending on the specific characteristics of your garage door. For the most accurate sizing, it is recommended to consult with a qualified garage door professional.

Incorrectly sized torsion springs can cause a number of problems, including difficulty opening or closing the door, premature spring failure, and potential safety hazards. Therefore, it is crucial to ensure that the correct torsion spring size is selected for your garage door.

If you are unsure about the size of torsion spring you need, seek assistance from a qualified garage door technician. They can assess your door and determine the appropriate spring size based on its weight, height, and width.

Regular maintenance and inspection of your garage door torsion springs are essential for ensuring optimal performance and safety. If you notice any signs of wear or damage to the springs, such as rust, cracks, or broken coils, contact a qualified technician immediately for repair or replacement.
