Learn how to choose the right key fob hardware size for your project. Compare 1 inch key fob hardware sets and find the best fit for your DIY key fobs, badges, and lanyards.
Quick answer
For most DIY key fob projects, 1 inch key fob hardware is the standard size that works with belting, ribbon, elastic, or fabric straps. Choose a set that includes clamps and split rings, and decide between a smaller bonus pack for testing designs or a larger pack for production runs.
Understanding key fob hardware sizes
Key fob hardware is designed to accommodate a specific strap width, which determines the overall look and function of your finished fob. The most common and versatile size is 1 inch key fob hardware, which fits standard belting, grosgrain ribbon, elastic, or fabric straps up to 1 inch wide. This size works well for keychains, badges, lanyards, and pet ID holders.
When choosing key fob making supplies, check the hardware's strap width specification. A 1 inch clamp means your finished strap should be exactly 1 inch wide to fit snugly. Using a narrower strap may cause the hardware to slide or look loose, while a wider strap won't fit at all. Always measure your material before buying.
Single set vs. multi-pack: what to consider
If you are new to making key fobs or only need a few for personal use, a smaller pack like the Dritz Key Fob Hardware Set - Bonus Pack, Nickel, 5 Sets gives you enough hardware to practice and create a handful of finished pieces. It includes clamps and split rings for five fobs, so you can test different strap materials without committing to a large quantity.
For those who plan to make multiple fobs for gifts, craft fairs, or ongoing projects, a larger pack such as the 1 inch Key Fob Hardware, Nickel, 12 Sets offers better value per set. With 12 sets of clamps and split rings, you can work through a batch efficiently and keep consistent hardware on hand. The trade-off is a higher upfront cost, but the per-set price is lower.
How to choose key fob hardware
- Match the strap width: Always confirm the hardware clamp size matches your strap material. The standard 1 inch hardware fits belting, ribbon, elastic, or fabric exactly 1 inch wide. Using a narrower strap may cause slipping. Measure your strap before buying.
- Decide on quantity: A 5-set pack is great for testing designs or making a few gifts. A 12-set pack offers better value if you plan to make many fobs or sell them. Buy larger packs for batch work.
- Consider the finish and material: Nickel hardware offers a classic, durable look that works with most strap colors. If you prefer a different finish, look for matching options in the same size. Nickel is a versatile choice.
