Choosing a bag fastening depends on the bag’s design, how it will be used and the level of security and access required. Zips suit enclosed openings, while side-release buckles work well for adjustable straps. D-rings, hooks, ladder locks, sliders and cord locks provide useful support for different bag styles and strap arrangements.

How to Choose the Right Fastening for a Bag
A fastening can change how a handmade bag looks, feels and works. A daily backpack needs a closure that can handle regular opening and closing, while a small pouch may only need a neat zip. Getting this choice right is one of the simplest bag-making tips for creating a finished item that feels practical and well-made.
So, what is the best fastening for a bag? The right choice depends on the bag style, fabric, strap, width, how often you'll use it and the finish you want.
At Realm Wholesale, you can find a range of bag-making supplies, including zips, side-release buckles, D-rings, hooks, ladder locks, sliders and polypropylene webbing. The wide collection includes several bag-making products, giving home sewists, hobbyists, makers and trade customers plenty of options for different projects.
What to Consider Before Choosing a Bag Fastening
Start with the bag's purpose, since a fastening for a lightweight handbag doesn't need the same setup as one for a backpack or travel bag. Consider the opening and ask whether you need the whole opening to close securely or if you want quick access. Then check the width and other elements of the webbing and hardware, since a buckle or slider needs to match the webbing it is designed for.
Among the bag-making tips for beginners, one of the most useful ones is to measure first and buy the hardware later. This can save a surprising amount of time and money when you start bag-making or sewing. You should also consider the material, as heavy fabric and structured bags may require stronger hardware and reinforced stitching at stress points.
When Is a Zip the Best Choice
A zip works well when you want a closed opening that keeps the bag's contents enclosed. It is a familiar choice for pouches, handbags, cases and many everyday bags. If you are deciding between a zip and a buckle for a bag, think about access. A zip usually gives you continuous access to the opening, while a buckle is useful when you want a fastening you can open and close quickly.
At Realm Wholesale, we stock several zip options, including brass-tooth jeans zips in lengths from 4 to 8 inches. These are primarily designed for jeans and trousers, but they may also suit creative sewing projects where the size and style are appropriate.
When Buckles Are the Better Option
Buckles are a good choice for bags that need adjustable or quick-release straps. They work well on backpacks, rucksacks, luggage and practical everyday bags.
Realm Wholesale offers black side-release buckles available in 20mm, 25mm, 38mm and 50mm webbing. They feature an easy press-and-release action, making them easy to operate.
Matching the buckle to the webbing is yet another useful bag-making tip, so remember to stock up on polypropylene webbing in various widths. Buckles are also a better option when you want to experiment with colour, as they come in multiple colours, including black, navy, rainbow, purple, royal blue, pink, burgundy, white, cerise, brown, yellow, red and khaki. This also gives you room to match your hardware to the fabric or create a contrast.
The Supporting Hardware That Makes a Difference
Choosing the main fastening is only part of making a bag. You also need the right supporting hardware to attach straps, adjust their length and make the finished bag functional. These details can be easy to miss when you are following a new pattern, but they can have a big impact on how the finished bag works. Here are some of the types of bag-making hardware to look out for:
1. D-Rings
D-rings are commonly used to connect a strap to a bag. You can sew them into fabric or attach them to other hardware, making them useful for shoulder straps, handles and crossbody bags.
The important thing is to match the D-ring to the strap width. For example, a 25mm strap requires hardware that accommodates 25mm webbing. Realm Wholesale stocks both metal and plastic D-rings, with plastic D-rings available in 25mm, 38mm and 50mm sizes.
If you are following a pattern, check its hardware measurements before ordering. It is a small step, but it can save you from discovering that your strap and hardware don't quite fit together.
2. Swivel Hooks
Swivel hooks are useful when you want a strap you can remove from the bag. The hooks attach to a D-ring or another suitable loop, while the swivel allows the strap to rotate as the bag moves. This makes them a practical choice for crossbody bags, detachable handles, backpacks and other designs where the strap needs to move freely. Realm Wholesale stocks metal and plastic hooks in 25mm, 40mm and 50mm sizes, so choose the size based on the width of the webbing you are using.
Another crucial bag-making tip for beginners is to remember that the stated size refers to the webbing the hook is designed to accommodate. Check the measurements and don't rely on how large the hook looks in a photograph.
3. Ladder Lock and Strap Adjusters
An adjustable strap needs a little more hardware than a fixed one. Ladder locks and strap adjusters let you change a strap's length, which is useful for gear worn across the body or over the shoulder.
Realm Wholesale stocks black plastic ladder locks for 25mm webbing and three-bar sliders in 25mm, 38mm and 50mm sizes. You can pair these with matching polypropylene webbing to create adjustable straps.
When choosing your hardware, keep the measurement consistent. If you are using 25mm webbing, for example, look for hardware also made for the same measurement. Matching these measurements is one of those simple bag-making tips that make assembly much easier.
Matching Your Fastening to Different Bag Types
By now, you can see that the best fastening depends on how you want the finished bag to look and work, and the bag style can help narrow your choice.
For example, a tote bag can have a simple open top, but a zip is useful if you want to keep the contents enclosed. Handles can be made from webbing and attached with suitable hardware. At the same time, a backpack needs a fastening that opens easily yet keeps the bag secure in motion. Side-release buckles are a practical choice for this design, especially when the straps also need adjustment.
A crossbody or messenger bag, for instance, benefits from a detachable or adjustable strap. Swivel hooks can make the strap easier to remove, while D-rings provide a neat attachment point. A drawstring bag, meanwhile, needs a cord lock to tighten and secure the opening. This works well for fabric bags, gym bags or even small storage bags where a zip or buckle may not be necessary.
