Quick answer
For most bag making projects, an 8 inch brass zipper works well for small pouches and clutches, while a 14 inch brass zipper is better for medium to large bags. If you need variety, the Zipper Grab Bag offers a mix of sizes and colors.

Why brass zippers are a top choice for bag making
Brass zippers are strong, durable, and have a classic look that complements waxed canvas and leather. They slide smoothly and are less likely to break than plastic zippers, making them ideal for bags that see daily use.
One trade-off is that brass zippers are heavier and slightly more expensive than nylon or plastic alternatives. However, the added weight and cost are justified by their longevity and aesthetic appeal.
Understanding zipper length: 8 inch vs 14 inch
The length of the zipper you need depends on the size of your bag opening. A general rule is to choose a zipper that is at least 2-3 inches longer than the opening to allow for seams and ease of installation.
An 8 inch brass zipper is perfect for small projects like coin purses, cosmetic bags, or the closure on a small crossbody bag. It provides enough length for a secure closure without excess bulk.
A 14 inch brass zipper suits medium to large bags such as totes, backpacks, or duffels. It gives you room to work with and ensures the opening is fully accessible.
When to consider the Zipper Grab Bag
If you are new to bag making or like to experiment with different sizes and colors, the Zipper Grab Bag is a practical option. It includes six assorted brass zippers in various lengths and colors, giving you flexibility for multiple projects.
Keep in mind that the Zipper Grab Bag is a final sale item and does not allow you to choose specific sizes. It is best for makers who enjoy surprises and want to build a small zipper stash.
How to choose the right brass zipper length
- Measure your bag opening: Measure the length of the opening where the zipper will go. Add 2-3 inches for seam allowance and ease of installation. This is the minimum zipper length you need. Write down the measurement before shopping.
- Match zipper length to bag size: For openings up to 6 inches, choose an 8 inch zipper. For openings between 6 and 12 inches, choose a 14 inch zipper. For larger openings, look for longer zippers or consider using a zipper grab bag for custom lengths.
- Consider the zipper type: Brass zippers are non-separating (closed end), which means they are best for bags with a single opening. They cannot be used for jacket-style closures. If you need a separating zipper, look for a different type. Confirm your bag design requires a closed-end zipper.
