How FixnZip Works

Find Your Zipper Size

Before you order the FixnZip, you will need to determine your zipper size. FixnZip comes in three sizes (small, medium & large).

Begin by checking the back of your broken zipper slider* as most have the size number (between 1 and 10) embossed on the back of the slider. Once you have this number the sizing chart below will guide you to the FixnZip size you require. 


Small: Zipper Sizes 1-4

  • Examples: Pants, Skirts, Fine Garments, Cushions and Clutch Handbags.

Medium: Zipper Sizes 5-7

  • Examples: Jackets, Sleeping Bags, Tents, Purses, Duffel Bags and Golf Bags.

Large: Zipper Sizes 8-10

  • Examples: Wetsuits, Boat Covers, Canvas Tents, Heavy Duty Clothing and Jeep Windows.
*If your zipper does not have a number on the back, you can simply measure the width of the zipper teeth in millimeters or inches. Refer to the below graphic.
