Guide to Using the Conversion Charts

When it comes to garage door spring replacement, one of the biggest challenges for both homeowners and technicians is finding an exact match. That’s why we created our Garage Door Spring Conversion Chart — a tool that helps you quickly find an equivalent garage spring in a different wire size.

This is especially useful when your current spring size is out of stock, discontinued, or uncommon — but we have a compatible spring in a larger wire size that will do the same job.

What Is Garage Door Spring Conversion?

Every torsion spring on a garage door is defined by:

Wire size (e.g., .207", .218", .225")

Length (in inches)

Inside diameter (commonly 1.75" or 2")

These variables work together to determine the spring's torque output—how much lifting power it provides.

Here's the key point:

👉 You can match the lifting strength of one spring with a different spring by adjusting wire size and length.

For example:

A 0.207" x 20" spring delivers the same torque as a 0.218" x 26" spring.

A 0.225" x 24" spring is compatible with a 0.234" x 29" spring in function.

Why Convert Instead of Replace with the Same Spring?

The main reason? Inventory compatibility.

You may have an existing spring size size that we don’t currently stock. Rather than wait or special-order it, you can use our conversion chart to find a spring in .218" or another wire size that’s functionally identical. This allows you to:

Complete your repair faster

Avoid overpaying for custom springs

Choose from in-stock parts that work

How Our Spring Conversion Chart Works

Our chart shows equivalent springs across multiple wire sizes. Just match your original spring’s torque output with the corresponding size in the wire gauge we have available. It’s a practical workaround that still ensures:

Proper door balance

Correct lift strength

Safe and smooth operation

Whether you're a homeowner doing a DIY garage door repair or a technician looking for a quick substitution, this tool takes out the guesswork.
