How Many Turns on a Garage Door Spring – A Complete Guide

Understanding the number of turns needed for a garage door spring is crucial for the proper functioning of your garage door. Incorrect adjustments can lead to serious issues, including safety hazards and damage to the door system. In this article, we will provide detailed information on how many turns on a garage door spring are necessary, including practical tips and insights from My Garage Door Repairman in Dallas, TX.


Garage door springs are essential components that balance the door’s weight, making it easy to open and close. A common question among homeowners is: “How many turns on a garage door spring are needed?” This question is vital because an improperly tensioned spring can cause operational problems and pose safety risks. In this guide, we’ll explore the process of adjusting garage door springs, ensuring your door operates smoothly and safely.

Why Proper Spring Tension is Important

The correct tension in garage door springs ensures the door opens and closes smoothly. Without the right number of turns on a garage door spring, you might experience issues such as:

  • The door being difficult to lift manually.
  • The automatic opener struggling to function.
  • Excessive wear on the opener mechanism.
  • Potential safety hazards if the door falls unexpectedly.

Types of Garage Door Springs

There are two main types of garage door springs: torsion springs and extension springs. Each type requires different handling and adjustment techniques.

Torsion Springs

Torsion springs are mounted above the garage door and twist to generate force. They are commonly used in modern garage doors and require precise adjustment to ensure balance.

Extension Springs

Extension springs are located on either side of the door and stretch to provide lifting force. These springs also need careful adjustment, although the method differs from torsion springs.

Determining the Right Number of Turns for Torsion Springs

The number of turns required on a torsion spring depends on the door’s height and the spring’s characteristics. Here’s a general guideline:

  • Measure the height of your garage door.
  • For a standard 7-foot door, 7.5 turns are typically required.
  • For an 8-foot door, around 8.5 turns are needed.

Step-by-Step Guide to Adjusting Torsion Springs

  • Safety First: Always wear safety glasses and gloves. Ensure the door is closed and unplug the opener.
  • Identify the Springs: Locate the torsion springs above the door.
  • Mark the Torsion Shaft: Use a marker to note the current position of the torsion shaft.
  • Loosen the Set Screws: Use a wrench to carefully loosen the set screws on the winding cone.
  • Wind the Spring: Using a winding bar, turn the spring the required number of turns. A 1/4 turn is generally one click on the winding cone.
  • Tighten the Set Screws: Once the desired number of turns is achieved, tighten the set screws.

Adjusting Extension Springs

For extension springs, adjustments involve:

  • Safety Measures: Wear protective gear and ensure the door is closed.
  • Locate the Springs: Identify the extension springs on either side of the door.
  • Adjust the Tension: Using a ratchet, adjust the hook or clamp to increase or decrease the tension.
