How to Choose the Right Magnetic Fastener for Your Leather Craft Projects
Magnetic fasteners can add both functionality and flair to your leather-crafting projects. With their sleek design and secure hold, they’re perfect for creating bags, wallets, belts, and custom accessories. But with so many options available, how do you choose the right one?
This guide will walk you through everything you need to consider when selecting magnetic fasteners. From size and strength to aesthetic appeal and functionality, you’ll learn how to make the best choice for your leather creations.

Why Magnetic Fasteners?
Before we dig into the specifics, it’s worth exploring why magnetic fasteners are so popular in leather crafting.
- Ease of Use: Magnetic clasps are incredibly easy to open and close with a simple snap or pull.
- Reliable Security: They provide a secure hold without the need for bulky buckles or complicated mechanisms.
- Versatile Design: Available in a range of finishes and styles, they suit a variety of projects – from minimalist wallets to luxurious handbags.
- Durability: High-quality magnetic fasteners are built to last, ensuring your leather project remains intact over time.
With these benefits in mind, it’s no wonder they’re a favourite among leather crafters.
Factors to Consider When Choosing a Magnetic Fastener
Selecting the right magnetic fastener is all about balancing form and function. Here are the key factors to keep in mind.
1. Size Matters
The size of your fastener needs to align with the scale of your project.
Small Projects
For compact items like wallets or coin pouches, a smaller magnetic fastener (e.g., 10–14mm in diameter) is ideal. These won’t overpower the design or add unnecessary bulk.
Large Projects
Bigger projects such as handbags or satchels require larger fasteners (e.g., 18–24mm). This ensures they can handle the additional weight and maintain a secure hold.
Take accurate measurements of your leather pieces before purchasing to ensure the fastener complements the overall size.
2. Magnetic Strength
Not all magnets are created equal. The strength of your fastener is critical to its functionality, especially for items that will carry weight.
Light Hold
For light-use objects like decorative leather keychains or diary covers, a standard magnetic pull (measured in gauss) is sufficient.
Heavy Hold
For heavy-duty projects like tote bags or laptop sleeves, opt for industrial-strength magnets. These are designed to withstand more force and prevent accidental openings. Always check the manufacturer's specifications to ensure the fastener matches your project’s requirements.
3. Project Type
Different leather projects call for different types of magnetic closures. Here are a few common scenarios and the best fastener options for each.
Leather Bags and Clutches
For bags and clutches, concealed magnetic snaps offer a clean and professional finish. They’re discreetly hidden, keeping the focus on your leatherwork while providing reliable closure.
Wallets and Card Holders
Thin disc magnets are a great fit for wallets and card holders, as they minimise bulk and provide a sleek look.
Belts and Straps
Magnetic buckles are perfect for belts or straps, combining aesthetic appeal with sturdy functionality.
Custom Accessories
If you’re making unique items like jewellery or gadget cases, neodymium magnets are highly versatile. They offer strong hold in a compact size, perfect for intricate designs.
4. Aesthetic Appeal
A magnetic fastener doesn’t just serve a practical purpose—it also enhances the overall look of your project.
- Finish Options:
Magnetic fasteners come in a range of finishes, including brass, nickel, gunmetal, and matte black. Choose a finish that complements your leather’s colour and texture.
- Shape and Style:
From rounded domes to flat discs, fasteners offer a variety of shapes to suit different designs. Consider which style aligns best with your project’s aesthetic.
- Hardware Matching:
Ensure your fastener aligns with other hardware elements (like buckles or rivets) for a cohesive and professional appearance.
5. Leather Thickness
Your leather’s thickness determines the type of attachment mechanism you’ll need.
Thin Leather (1–2mm)
For thinner leather, pronged magnetic clasps work well. These are inserted through the material and secured with a backing plate, making them easy to attach.
Thick Leather (3mm and Above)
For thicker leather, sew-in or glue-in magnets are more suitable. These fasteners often come with special grooves or adhesive backs for secure placement.
6. Installation Method
Some magnetic fasteners require tools for installation, while others are designed for a simple, no-fuss application.
- Pronged Snaps:
Easy to attach with basic tools like a hole punch and a pair of pliers. Ideal for beginners.
- Sew-In Magnets:
Require a sewing machine or needle and thread but offer a seamless finish.
- Adhesive-Backed Magnets:
Perfect for quick projects, as they can be stuck directly onto the leather.
When choosing your fastener, think about the tools and skills you have available.
Tips for Installing Magnetic Fasteners
Once you’ve chosen the perfect magnetic fastener, follow these tips for a professional finish.
- Mark Placement Carefully
Use a ruler and chalk to mark the exact placement of your fastener before cutting into your leather. Precision is key.
- Reinforce the Area
Apply an extra layer of leather or fabric backing to the attachment area to prevent tearing over time.
- Test Before Finalising
Always test the fastener’s hold and alignment before completing your project. Ensure it opens and closes smoothly.
