Finding Your Replacement Zipper Slider Size

Before you order the FixnZip®, you should determine your zipper sizes.

Chances are that you have come to this page because you have a broken zipper that needs replacing. By now, you have probably also realized that zippers come in different sizes, and it is important to know what size you need to continue your replacement process. In that case, allow us to help you understand how to tell what size zipper you need.

To determine the replacement zipper slider size you need, start by checking the back of your broken zipper slider. Most zippers have a size number (1-10) embossed on the back of the slider. Once you locate the number, our sizing chart below will determine which FixnZip® replacement zipper slider size is right for you.

Small:  Sizes 1-4
Examples: pants, skirts, fine garments, cushions, clutch handbags

Medium: Sizes 5-7
Examples: jackets, sleeping bags, tents, purses, duffel bags, golf bags

Large: Sizes 8-10
Examples: wetsuits, boat covers, canvas tents, heavy duty clothing, jeep windows

Measure Your Zipper

If your zipper doesn’t have a number on the back, you can simply measure the
width of the zipper teeth in millimeters or inches.

Teeth/Coil Width
1 to 4.5 mm  |  0.04 to 0.18 in = Small
5 to 7.5 mm  |  0.19 to 0.30 in = Medium
8 to 10 mm  |  0.31 to 0.40 in = Large
