Staple Sizes and Types: The Complete Guide to Choosing the Right Staples

When it comes to fastening, staples are one of the most reliable and versatile options. But with so many staple sizes, types, and gauges available, choosing the right one can be confusing. Whether you’re working on office documents, upholstery, or construction projects, knowing how to select the right staple is essential for ensuring strength, durability, and a clean finish.

In this guide, we’ll explain the different staple sizes, types of staples, and staple gauges so you can pick the best option for your project.

Staple Sizes Explained

Staples are measured by two key dimensions:

Crown width → the top of the staple.

Leg length → the part that penetrates the material.

Choosing the right size depends on how thick your material is.

Mini staples (2mm – 6mm legs)

Best for paper, fabric, and other thin materials.

Standard staples (6mm – 12mm legs)

Common for home, school, and light-duty projects.

Heavy-duty staples (12mm – 22mm legs)

Perfect for upholstery, woodworking, and fastening thicker stacks.

Extra-long staples (22mm – 50mm legs)

Designed for construction, industrial packaging, and deep fastening.

👉 Tip: Always choose a staple leg length that’s about three times the thickness of the material you’re fastening.

Different Types of Staples

There are several types of staples, each made for specific uses:

Office Staples – Standard staples for paper documents.

Heavy-Duty Staples – Built for cardboard, light wood, or thick stacks of paper.

Upholstery Staples – Narrow-crown staples for attaching fabric to furniture.

Construction Staples – Wide-crown staples used in flooring, roofing, insulation, and wiring.

Specialty Staples – Includes cable staples, stainless steel staples (rust-resistant), and even medical staples for surgery.

Staple Gauges

The gauge of a staple refers to the wire thickness. The lower the number, the thicker and stronger the wire.

Thin Wire Staples (20–22 gauge) → Light-duty tasks like paper and fabric.

Medium Wire Staples (18–19 gauge) → Perfect for upholstery, crafts, and general projects.

Heavy Wire Staples (15–17 gauge) → Designed for construction, flooring, and industrial use.

How to Choose the Right Staples

When deciding which staple to use, consider:

Material thickness → Make sure the staple leg is long enough to penetrate.

Type of project → Office work vs. upholstery vs. heavy-duty construction.

Environment → For outdoor use, choose galvanised or stainless steel staples to prevent rust.

Stapler compatibility → Always check your stapler or staple gun’s manual for the correct sizes and types.

Understanding staple sizes, types, and gauges will help you choose the right fastener for any job. From light office use to heavy-duty construction, the right staple ensures your work stays secure and professional.
