A busted zipper is not the end of the world. Whether you can sew or prefer no-sew techniques, you can replace a zipper on anything with these tips and tricks. For some projects, you might have to figure out how to tell what size zipper slider you need before you get started. Keep reading to find out what to do when your zipper fails.

Determine Zipper Material

To replace your zipper, you will first need to determine what material you are working with. The slider must match the material to ensure the pull tab will move over the teeth properly. Common materials used for zippers include:

  • Molded plastic
  • Nylon coil
  • Metal

Determine the Gauge of Your Zipper

Look at the number on the tab of your zipper to figure out what size zipper slider you need. The gauge tells you the thickness of the teeth and determines how wide the slider needs to be. Zippers with higher gauges are typically more durable.

Measure Your Zipper

If your zipper doesn’t list a gauge number, you may have to measure it to find the right zipper head replacement. While the teeth are closed, measure the distance across them in millimeters. This number will be your gauge.

Locking vs. Non-locking Zippers

When you purchase a replacement slider, you will have the option to choose a locking or non-locking slider. Non-locking sliders move when any part of the zipper or slider is moved, even by pulling the teeth apart. Locking sliders have a small mechanism that engages to prevent the tab from moving unless you pull on it.
