Staples Sizes by Gauge

When it comes to staple gun staples, their size is measured by the gauge – the higher the gauge number, the thinner the wire. For lightweight materials, such as fabrics or thin pieces of wood, staple gun staples with a higher gauge number, such as 18 or 20, will be the best option. On the other hand, for thicker materials, like hardwood or metal, staple gun staples with a lower gauge number, such as 16 or 14, will be needed to ensure a secure hold.

It’s important to choose the right size staple gun staples to prevent damage to your materials and to achieve the best results. So, next time you’re wondering what size are staple gun staples, remember to consider the gauge and the thickness of the material you’re working with.

18 Gauge

Staples sized by gauge are important to consider when choosing the right staple for a project. The gauge refers to the thickness of the staple wire, with a lower gauge number representing a thicker wire. 18 gauge staples, for example, are thicker than 20 or 22 gauge staples.

These staples are commonly used in construction and woodworking projects, as they offer a strong hold without causing any damage to the material being stapled. They are also compatible with most staple guns, making them a versatile option for DIY enthusiasts and professionals alike. When choosing the right staple size for a project, it’s important to take into account the material being stapled and the amount of holding power needed.

Using the wrong size staple can lead to complications, such as the staple breaking or not penetrating through the material. By carefully considering the gauge size and other factors, it’s possible to find the perfect staple for any job.

16 Gauge

When it comes to staples, one important factor that you need to consider is the gauge, which refers to the thickness of the wire used to make the staple. A 16 gauge staple is one that is moderately thick, making it ideal for a variety of tasks. This size of staple works well for securing fabrics, upholstery, and other materials together without being too thick or bulky.

It’s also commonly used in construction, such as attaching wood boards and other materials. However, it’s important to note that not all staple guns are compatible with 16 gauge staples, so be sure to check the specifications of your tool before making a purchase. Overall, 16 gauge staples are a reliable and versatile option that can be used across a wide range of applications.

15 Gauge

When it comes to stapling, the gauge of the staple is an important factor to consider. The 15-gauge staple size, for instance, is a popular choice for heavy-duty applications such as roofing, insulation installation, and woodworking. This size produces a thick, sturdy staple that can penetrate through tough materials efficiently while ensuring a reliable hold.

Because of its thickness, it’s less likely to bend or break when exposed to heavy loads or stress. However, it’s important to note that not all staplers are compatible with 15-gauge staples, so it’s vital to check your tool’s specifications before purchasing them. Overall, the 15-gauge staple size is an excellent choice for heavy-duty projects that require a secure hold and reliable fastener.

Staples Sizes by Length

When it comes to staple gun staples, the size can vary based on the length needed for the project you’re working on. Common sizes range between ¼ inch to 1 inch in length. Shorter staples, such as ¼ inch, are ideal for thin materials like paper and cardboard.

Medium-sized staples, in the ⅜ to ½ inch range, are great for upholstery, fabric, and light woodwork. Longer staples, ranging from ⅝ to 1 inch in length, are better suited for heavier woodwork and construction. It’s important to choose the appropriate staple size for your project to ensure a secure hold and proper functioning of your staple gun.

Remember to always double-check the size before loading your staple gun and keep different sizes on hand for different tasks. By understanding the variety of staple sizes available, you can tackle any job with ease.

Shorter Sizes (1/4 inch to 1/2 inch)

When it comes to staples, there are various sizes available in the market. If you need to staple fewer pages together, the shorter staples ranging from 1/4 inch to 1/2 inch in length would be the perfect choice for you. These staples are ideal for stapling up to 25 sheets of paper together, making them great for home or office use.

They are also perfect for use in crafting projects, such as attaching fabric or paper together. Remember, it’s essential to choose the right size of staple for the job, as a staple that is too long may not go through the paper, while one that is too short may not hold the pages together firmly enough. In summary, if you want to staple fewer pages, the shorter staple sizes ranging from 1/4 inch to 1/2 inch are perfect for the job.

Medium Sizes (5/8 inch to 1 inch)

If you’re looking for staples that are a bit larger than the small sizes, medium staples are exactly what you need. These staples come in sizes ranging from 5/8 inch to 1 inch, making them perfect for a variety of tasks. If you need to staple together a thicker stack of papers, or you’re working with cardboard or fabric, these staples will get the job done.

The larger size allows them to penetrate deeper, ensuring a secure hold that won’t come apart easily. Plus, with the wide range of lengths available, you can find the perfect staple to suit your needs. From shorter staples for smaller projects to longer staples for larger ones, there’s a staple out there that’s perfect for every job.

So next time you’re in need of a staple, think about what size you need and choose a medium staple to get the job done right.

Longer Sizes (1-1/8 inch to 2 inch)

When it comes to stapling, longer staples are sometimes necessary for thicker stacks of paper or even fabrics. The range of longer staple sizes starts at 1-1/8 inch and goes all the way up to 2 inches in length. These staples can be used for heavy-duty tasks like securing furniture upholstery or carpet.

It’s important to note that not all staplers can handle longer staples, so it’s essential to ensure compatibility before use. With longer staples, it’s also crucial to make sure the staple gun is adjusted correctly to avoid damaging the material being stapled. When used correctly, longer staples can make difficult tasks much easier, saving time and reducing frustration.

So, if you’re faced with a heavy-duty stapling job, don’t hesitate to try out some longer staples and see how they can make your work more comfortable and more efficient.


In summary, asking what size staple gun staples are is like asking what size spoon you need for soup. It all depends on the job at hand! So, whether you’re repairing upholstery or building a birdhouse, make sure to do your research and pick the perfect size staple for the task. Happy stapling!”
