If you’re a homeowner, you probably know that garage doors are an essential part of your home’s security and curb appeal. But have you ever wondered how they work? One critical component of a garage door is the spring that helps it open and close. These springs are under a lot of tension, and if they break, it can be dangerous.
So, how many turns does a garage door spring need? The answer depends on the height of your garage door. Generally, the rule of thumb is that for every foot of door height, the spring requires one full turn plus an additional quarter turn. For example, if your garage door is seven feet tall, it would need seven full turns plus a quarter turn. If it’s eight feet tall, it would require eight full turns plus a quarter turn.

Understanding Garage Door Springs
If you have a garage door, you know how important it is to keep it functioning properly. One of the most crucial components of a garage door is the spring. Garage door springs are responsible for lifting and lowering the door, and they come in two main types: torsion springs and extension springs.
Torsion Springs
Torsion springs are located above the garage door and are wound tightly to create tension. When the door is opened, the tension is released, and the springs unwind to lift the door. When the door is closed, the springs wind back up to create tension again. Torsion springs are typically used on heavier doors and can last for up to 20,000 cycles.
Extension Springs
Extension springs are located on either side of the garage door and are stretched to create tension. When the door is opened, the springs contract to lift the door. When the door is closed, the springs expand to create tension again. Extension springs are typically used on lighter doors and can last for up to 10,000 cycles.
It is important to note that garage door springs can be dangerous to work with and should only be serviced by a trained professional. Attempting to repair or replace a spring on your own can result in serious injury or even death.
When it comes to determining how many turns to put on your garage door spring, it is important to consult the manufacturer’s specifications or a professional. However, as a general rule of thumb, a full turn should be added for every foot of garage door height, with an additional 3/4 turn at the end. For example, if you have a standard 7-foot garage door, it will require a total of 7 revolutions plus a 3/4 turn at the end (7 3/4 full turns).
Overall, understanding the different types of garage door springs and how they work can help you better maintain your garage door and keep it functioning properly for years to come.
How Garage Door Springs Work
If you have ever wondered how your garage door works, you are not alone. The garage door spring is a crucial component that makes it possible for your door to open and close smoothly. In this section, we will explore how garage door springs work, and what factors determine how many turns you need to put on your garage door spring.
Tension and Height
The tension of the garage door spring is what allows it to lift the weight of the garage door. The amount of tension needed depends on the height of the door. The taller the door, the more tension is required. This is because the spring needs to be able to counteract the weight of the door as it opens and closes. The number of turns needed on the spring is directly related to the height of the door.
Weight and Turns
The weight of the garage door is another important factor in determining how many turns you need to put on the spring. The heavier the door, the more turns are required to provide the necessary tension to lift it. A lighter door requires fewer turns. It is important to note that the number of turns needed is not determined by the weight of the door alone, but rather by the combination of the weight and height of the door.
Here is a table that shows the recommended number of turns based on the height of the door:
| Door Height | Number of Turns |
|---|---|
| 7 feet | 31 quarter turns |
| 8 feet | 34 quarter turns |
Remember, this is just a general guideline. The number of turns needed can vary based on the weight of the door and other factors. It is always best to consult a professional if you are unsure about how many turns to put on your garage door spring.
Determining the Number of Turns on a Garage Door Spring
If you need to replace or adjust your garage door spring, it’s important to determine the number of turns required for your specific garage door. Below, we’ll explain how to calculate the number of quarter and full turns needed for your garage door spring.
Quarter Turns
A quarter turn is the amount of rotation needed to wind the garage door spring one-fourth of the way. To determine the number of quarter turns required for your garage door spring, you’ll need to measure the height of your garage door. Here’s a chart to help you calculate the number of quarter turns needed:
| Garage Door Height | Number of Quarter Turns |
|---|---|
| 7 feet | 7-1/2 |
| 8 feet | 8-3/4 |
| 9 feet | 10 |
| 10 feet | 11-1/4 |
Full Turns
A full turn is the amount of rotation needed to wind the garage door spring once all the way around. To determine the number of full turns required for your garage door spring, you’ll need to use the number of quarter turns calculated in the previous step. Here’s a chart to help you calculate the number of full turns needed:
| Number of Quarter Turns | Number of Full Turns |
|---|---|
| 7-1/2 | 30 |
| 8-3/4 | 35 |
| 10 | 40 |
| 11-1/4 | 45 |
Keep in mind that these charts are general guidelines, and the exact number of quarter and full turns needed for your garage door spring may vary depending on the manufacturer’s specifications or other factors. If you’re unsure about how many turns your garage door spring needs, it’s best to consult a professional.
Adjusting the Number of Turns on a Garage Door Spring
If you need to adjust the number of turns on your garage door spring, follow these steps:
- Close the garage door and disconnect it from the opener by pulling the emergency release cord.
- Use winding bars to loosen the set screws on the torsion spring. Make sure to keep a firm grip on the winding bars while doing this.
- Remove the old winding bars and insert new ones into the holes on the spring cone. Make sure the bars are securely in place.
- Turn the winding bars in the direction that tightens the spring. To determine the number of turns needed, use the guidelines provided by the manufacturer or consult a professional.
- Once you have completed the necessary turns, tighten the set screws on the torsion spring. Make sure they are tight enough to prevent the spring from unwinding, but not so tight that they damage the spring.
- Test the garage door to make sure it is balanced and operating smoothly. If necessary, make further adjustments to the spring tension.
Remember, adjusting the number of turns on a garage door spring can be dangerous if not done properly. If you are unsure about how to do it, consult a professional.
How Many Turns on a Garage Door Spring: Quick Recap
When it comes to determining the number of turns on a garage door spring, there are a few things to keep in mind. First, the number of turns required is dependent on the height of the garage door. Second, it is important to keep track of the number of turns you make on each spring. Finally, it is always recommended to seek the assistance of a professional if you are unsure about making any adjustments to your garage door springs.
As a general rule, for an 8-foot door, it will require 8 ¾ full turns on each spring. For a 10-foot door, it will be 10 ¾ turns, and so on. However, it is important to note that these are just general guidelines and may not apply to all garage doors.
If you are unsure about how many turns to make on your garage door springs, it is best to consult with a professional. Attempting to adjust the springs on your own can be dangerous and can cause serious injury if not done properly.
Remember, garage door springs are under a lot of tension and can cause serious injury if mishandled. If you are unsure about how to make any adjustments to your garage door springs, it is always best to seek the assistance of a professional.
