Metal Snap Buttons vs. Plastic Snap Buttons: Which Are Better?

Quick answer

For heavy-duty projects like jeans or outerwear, metal snap buttons are the stronger choice. For lightweight fabrics, delicate garments, or projects where you want to avoid rust, plastic snap buttons are often more practical. Consider the fabric weight and how often you'll wash the item.

Snap buttons are a fast, reliable closure for everything from baby clothes to bags. But when you stand in the notions aisle, the metal-versus-plastic decision can feel surprisingly tricky. Each material brings distinct strengths, and the right pick depends on the fabric you're sewing and how the finished piece will be used.

This comparison looks at the real trade-offs between metal and plastic snap buttons. We'll cover durability, fabric compatibility, care requirements, and cost so you can choose with confidence.

Durability and strength

Metal snap buttons are the classic choice for heavy-duty items. They withstand repeated stress, resist bending, and hold securely on thick fabrics like denim, canvas, and upholstery. If you're making jeans, a work apron, or a sturdy tote, metal snaps are the dependable option.

Plastic snap buttons are lighter and less rigid. They work well for garments that don't face heavy strain, such as blouses, dresses, or children's clothing. However, they can crack under extreme pressure or become brittle in very cold temperatures. For most sewing projects, though, plastic snaps offer plenty of holding power when used appropriately.

Fabric compatibility

Fabric weight and drape matter when choosing snap material. Metal snaps are heavier and can pull on lightweight or sheer fabrics, distorting the look of a delicate blouse. They are best reserved for medium-to-heavyweight woven fabrics that can support the extra weight.

Plastic snaps are gentler on fine materials. They don't weigh down sheer or soft fabrics, making them ideal for lingerie, baby clothes, and lightweight cotton. Because they are less bulky, they also create a smoother profile on the inside of a garment.

Care and maintenance

Washing and drying affect snap buttons differently. Metal snaps can rust over time, especially if they aren't coated or if the garment is frequently exposed to moisture. To protect them, you might need to remove metal snaps before washing or use a gentle cycle. This extra care is often worth it for the classic look and feel of metal.

Plastic snaps are naturally rust-proof and require no special care. You can toss items with plastic snaps in the washing machine without worrying about corrosion. This makes them a low-maintenance choice for everyday clothing, kids' wear, and items that get washed often.

Aesthetics and cost

Metal snaps have a timeless, polished appearance that adds a professional finish to jeans, jackets, and bags. They are often chosen for their visual weight and the satisfying click they make when closed. However, this quality usually comes with a higher price tag.

Plastic snaps are available in a wide range of colors and finishes, including matte and glossy options. They can mimic the look of metal when needed, but they generally cost less. For budget-conscious projects or when you need many snaps, plastic is the economical choice.

Metal vs. plastic: trade-offs at a glance

• Metal for durability: Choose metal snaps for jeans, jackets, bags, and other items that need to withstand heavy use and tension. They provide a secure closure and a classic look. Best for heavy fabrics and high-stress closures.
• Plastic for lightweight fabrics: Plastic snaps are ideal for delicate materials like silk, chiffon, and lightweight cotton. They won't weigh down the fabric and are rust-proof. Best for garments that are washed often or made from fine fabrics.
• Consider care requirements: If you prefer low-maintenance laundry, plastic snaps are easier to care for. Metal snaps may need extra attention to prevent rust. Decide based on how you'll use and wash the finished item.
