How to tell garage door spring size?

Welcome to the MM Garage Door Repair Utah blog! As your local garage door experts, we often get asked about garage door springs. Specifically, homeowners want to know how to determine the size of their garage door springs. Understanding your spring size is crucial for ordering replacements and ensuring your garage door operates safely and efficiently. Attempting to replace springs without the proper knowledge can be dangerous, so we always recommend consulting with a professional. However, if you’re simply trying to identify the size for informational purposes, this guide will help. Let’s dive in!

Why Knowing Your Garage Door Spring Size Matters

Garage door springs are responsible for counterbalancing the weight of your garage door, making it easy to open and close. They work under immense tension, and selecting the wrong size can lead to several problems, including:

• Door Imbalance: An incorrectly sized spring won’t properly balance the door, making it difficult to lift and potentially causing the opener to work harder and fail prematurely.
• Safety Hazards: A spring that’s too weak can snap under the door’s weight, posing a serious safety risk. A spring that’s too strong can cause the door to slam open or closed.
• Premature Wear and Tear: Using the wrong springs can put excessive stress on other garage door components, leading to faster wear and tear.

Therefore, accurately identifying your garage door spring size is essential for safety, performance, and longevity.

Safety First When Inspecting Garage Door Springs

WARNING: Garage door springs are under extreme tension and can cause serious injury or death if mishandled. If you are not comfortable working with springs, please contact a qualified garage door technician. MM Garage Door Repair Utah is available to assist you. Never attempt to loosen, adjust, or remove a spring without the proper tools and knowledge.

Before you even think about inspecting your springs, ensure the garage door is fully closed and, ideally, disconnected from the opener. This will minimize the risk of accidental movement during your inspection.

Steps to Determine Your Garage Door Spring Size

Here’s a step-by-step guide to help you determine the size of your garage door springs:

Step 1: Identify the Spring Type

There are two main types of garage door springs:

• Torsion Springs: These are mounted above the garage door opening, on a torsion tube. They are typically longer and thicker than extension springs.
• Extension Springs: These are located on either side of the garage door, running along the horizontal tracks. They extend and contract as the door moves.

This guide primarily focuses on torsion springs, as they are more common and require more precise sizing.

Step 2: Gather Your Tools

You’ll need the following tools:

• Tape Measure: For measuring the spring’s length and wire size.
• Winding Bars (If you plan to replace the springs yourself): These are essential for safely winding and unwinding torsion springs. (Again, we strongly recommend professional assistance for spring replacement.)
• Permanent Marker: For marking the spring’s position before removal (if applicable).
• Scale (Optional): To weigh the garage door.

Step 3: Measure the Spring’s Length

Measure the total length of the spring in inches. This is the distance from one end of the spring to the other, excluding the cones (the metal pieces at each end). If the spring is broken, carefully piece it together to get an accurate measurement.

Step 4: Measure the Wire Size (Diameter)

This is the most crucial and often the trickiest part. You need to measure the diameter of a single coil of the spring. The most accurate way to do this is to measure 10-20 coils and then divide by the number of coils measured. This gives you the average wire diameter. For example, if 10 coils measure 2 inches, the wire diameter is 0.2 inches.

Alternatively, you can use a wire gauge to determine the wire size. Wire gauges are available at most hardware stores.

Step 5: Measure the Inside Diameter

Measure the inside diameter of the spring in inches. This is the distance across the inside of the spring. Place the tape measure inside the spring to get an accurate reading.

Step 6: Determine the Wind Direction

Garage door torsion springs come in two wind directions: right-wound and left-wound. Looking at the spring from the end, determine which direction the coils wind. A right-wound spring will wind clockwise, while a left-wound spring will wind counter-clockwise. Typically, the right-wound spring is installed on the left side of the door, and the left-wound spring is installed on the right side.

Step 7: Weigh the Garage Door (Optional but Recommended)

Knowing the weight of your garage door helps ensure you select the correct spring strength. You can find the weight on the manufacturer’s label or weigh the door using a bathroom scale and some ingenuity. Open the door halfway and place the scale under the bottom edge. Carefully lower the door onto the scale. This will give you an approximate weight.

Understanding Spring Color Codes

Many garage door springs are color-coded to indicate their size and strength. While these color codes can be helpful, they are not standardized across all manufacturers. Therefore, it’s always best to verify the measurements you take with the color code. Common color codes include:

• Red: Typically indicates a higher spring rate.
• Green: Often used for standard-duty springs.
• Blue: May indicate a lighter spring rate.
• Orange: Another common color for standard springs.

Remember, color codes are not a substitute for accurate measurements.

FAQs About Garage Door Springs

Q: Can I replace just one garage door spring?

A: While it’s technically possible, we strongly recommend replacing both springs at the same time. Springs wear out at roughly the same rate, and replacing only one can lead to imbalance and premature failure of the other spring.

Q: How long do garage door springs last?

A: The lifespan of a garage door spring depends on several factors, including usage frequency, spring quality, and maintenance. On average, springs last between 7 and 12 years.

Q: What are the signs that my garage door spring is failing?

A: Common signs include difficulty opening or closing the door, a loud snapping sound, visible damage to the spring, and the door appearing uneven or unbalanced.

Q: Can I use a different size spring than the original?

A: No. Using a different size spring can compromise the safety and performance of your garage door. Always use the correct size spring for your door’s weight and dimensions.

Q: Are there high-cycle springs available?

A: Yes, high-cycle springs are designed for doors that are opened and closed frequently. They are made from higher-quality materials and are built to last longer.
