Find my zipper size number
Chances are that you have come to this page because you have a broken zipper that needs replacing. Before you order your FixnZip®, you should determine your zipper size.
FixnZip comes in three sizes, small, medium and large. These sizes will cover almost any zip.
First step, turn your old zipper over (if you still have it) and there should be a size number between 1-10 embossed on the back of the slider. Now use our chart to determine what size Fixnzip you’ll need.
#1-4 = Small
Examples: pants, skirts, fine garments, cushions, clutch handbags
#5-7 = Medium
Examples: jackets, sleeping bags, tents, purses, duffel bags, golf bags
#8-10 = Large
Examples: wetsuits, boat covers, canvas tents, heavy duty clothing, jeep windows
Measure the zipper
If your zipper doesn’t have a number on the back, you can simply measure the width of the zipper teeth (coil) in millimetres. The measurement is from the outside edges of the zipper (see diagram). Once you’ve determined your zipper width, you can select which FixnZip will work best using the following guide:
Zipper teeth/coil width
1 to 4.5 mm = Small
5 to 7.5 mm = Medium
8 to 10 mm = Large
