What size torsion spring for 16×7 garage door?


When it comes to garage doors, torsion springs play a crucial role in providing the necessary counterbalance to make opening and closing the door easier. If you have a 16×7 garage door, you might be wondering what size torsion spring is suitable for your specific door. In this article, we will delve into the factors that determine the size of torsion springs for a 16×7 garage door, ensuring you have a better understanding of what to look for.

Factors Affecting Torsion Spring Size

Door Weight: The weight of the garage door is a primary factor in determining the appropriate size of the torsion spring. A heavier door will require a stronger spring to provide the necessary counterbalance. The weight of a 16×7 garage door can vary depending on the material used, such as steel or wood.

Spring Type: There are two main types of torsion springs: standard torsion springs and high-cycle torsion springs. Standard torsion springs are designed for typical residential use and have a lifespan of around 10,000 cycles. High-cycle torsion springs, on the other hand, are built to withstand more cycles, making them suitable for commercial or high-traffic applications.

Spring Length: The length of the torsion spring is another crucial factor to consider. It should be long enough to fit on the torsion shaft and provide the necessary torque to counterbalance the door. The length of the spring will depend on the height of the garage door, which is 7 feet in the case of a 16×7 door.

Wire Size: The wire size of the torsion spring determines its strength. Thicker wire sizes provide more strength and are suitable for heavier doors, while thinner wire sizes are appropriate for lighter doors. The wire size is typically measured in gauge, with smaller gauge numbers indicating thicker wire.

Consulting a Professional

While understanding the factors that affect torsion spring size is essential, it is highly recommended to consult a professional garage door technician or supplier to determine the exact size you need. They have the expertise and knowledge to assess the specific requirements of your garage door, taking into account factors such as the door’s weight, track system, and other individual considerations.

A professional will also consider the necessary spring torque, which is determined by the door’s height and track radius. This torque ensures that the spring can effectively counterbalance the door’s weight, making it safe and easy to operate.


Determining the appropriate size of torsion spring for a 16×7 garage door involves considering factors such as the door’s weight, spring type, length, and wire size. While understanding these factors is helpful, it is always recommended to consult a professional to ensure accurate sizing and proper installation. A professional will assess the specific requirements of your garage door and provide the right torsion spring for optimal performance and safety.
