Zipper Gauge & Chain Size Chart
Introduction
Understanding zipper gauge and chain size is essential for selecting the right zipper for
your project. The gauge refers to the width of the zipper teeth when closed, typically
measured in millimeters. This guide provides a comprehensive overview of zipper
gauges, their corresponding measurements, and common applications.
What is Zipper Gauge?
Zipper gauge, often denoted by a number (e.g., #3, #5, #10), indicates the width of the
zipper teeth when the zipper is closed. The higher the number, the wider and more
robust the zipper teeth. For example, a #5 zipper has teeth approximately 5mm wide.
This measurement helps determine the zipper's strength and suitability for various
applications.
Zipper Gauge Chart
| Gauge | Teeth Width (mm) | Common Applications |
|---|---|---|
| #2 | 2 mm | Lightweight fabrics, small pouches |
| #3 | 3 mm | Dresses, skirts, cushions |
| #4.5 | 4.5 mm | Handbags, medium-weight garments |
| #5 | 5 mm | Jackets, backpacks, upholstery |
| #7 | 7 mm | Tents, heavy-duty bags |
| #8 | 8 mm | Outdoor gear, marine applications |
| #10 | 10 mm | Sleeping bags, industrial covers |
| #12 | 12 mm | Large tents, marine canvas |
| #15 | 15 mm | Oversized covers, portable shelters |
Note: Measurements are approximate and can vary slightly based on manufacturer
specifications.
How to Measure Zipper Gauge
- 1. Close the zipper to ensure accurate measurement.
- 2. Use a caliper or ruler to measure the width of the teeth from one outer edge to the other.
- 3. Exclude the fabric tape from your measurement; focus solely on the teeth.
Tip: Some zippers have the gauge number stamped on the back of the slider for quick
reference.
Selecting the Right Gauge
Choosing the appropriate zipper gauge depends on the material weight and the
intended use of your product.
- Lightweight fabrics (e.g., silk, chiffon): Opt for smaller gauges like #2 or #3.
- Medium-weight fabrics (e.g., cotton, polyester): Consider gauges #4.5 or #5.
- Heavy-duty applications (e.g., canvas, leather): Use larger gauges like #8, #10, or higher.

Understanding zipper gauges and chain sizes is crucial for ensuring the durability and
functionality of your products. By selecting the appropriate gauge, you can enhance the
