What Size Staples For 30lb Felt? (Fully Explained)

Have you ever had a project that needed to be completed, but you were left scratching your head trying to figure out what size staples you should use? 

Well, then, you’ve come to the right place. We’re here to help you ensure your projects are always stapled correctly.

Today, we’ll focus on choosing the right size staple for 30lb felt. We’ll walk you through everything from factors to consider when choosing stapler felt and its uses. 

By the end of this article, you won’t have any questions about what size staples for 30lb felt.

What Are 30lb Felt Staples?

When it comes to stapling 30lb felt, you want to ensure your staples are up for the job. What does that mean? You must select the correct size staple for the felt weight.

But what are 30lb felt staples exactly? They’re generally made from either steel or stainless steel and come in various shapes and lengths. 

The most common types are T-50 staples, which feature two legs that help secure the felt in place; U-shaped staples; and flat-headed staples.

These different shapes of staples all serve different functions. For example, U-shaped staples offer better resistance against tearing and provide a more secure bond than flat-headed staples. 

T-50 staples are usually used when attaching heavy materials like carpet or upholstery, while flat-headed staples are great for lighter materials such as fabrics. 

So, depending on your project, you can select the right shape of 30lb felt staple to get the job done.

What Size Staples is Best For 30lb Felt?

The truth is, a few factors will determine what size staple you’ll need. Those factors include the type of stapler you’re using, the thickness of the felt, and the job.

Thickness of material

A 22 gage is a good all-around staple for most thin to medium-weight fabrics like cotton and wool and heavier-weight fabrics like drapery and denim. 

In other words, it should hold up nicely with your 30lb felt projects. It’s important to note that heavier gages (like 18 or 16) can be too large for thinner materials, while smaller gages (like 24 or 26) can easily bend or break on heavier materials. 

But here’s the good news: typically, a 22-gage staple will be perfect for your 30lb felt projects. It provides just the right balance between strength and flexibility.

Stapler type

You’ll also need to consider what kind of stapler you use when choosing your staple size. 

Manual staplers have limited power and may not be able to handle thicker staples like 16 or 18-gage fasteners, so sticking with something in the 22-24 range will give better results.

For electric staplers, though, thicker staples may be fine depending on their power rating—just make sure you check your owner’s manual first! A 22-gage staple should work fine for most 30lb felt projects. 

Common Uses of the 30lb Felt Staples

A few common uses come to mind when you’re talking about 30lb, felt staples. Here’s a quick rundown of some popular applications:


In roofing, 30lb felt staples would get the job done. This felt type benefits applications that don’t require a heavier weight — it’s cost-effective and reliable in keeping your roof secure. 

A great way to ensure your roof lasts longer is by stapling the edges of your felt to the roof deck or sheathing.


The 30lb felt staple could also be used for upholstering furniture, providing just enough holding power while maintaining an attractive look. 

Plus, the more compact size of these staples means that they’ll blend in nicely with the larger materials surrounding them, like fabric, foam, and batting!


30lb felt staples are also famous for insulation applications since they’re light enough not to damage the material. 

These staples are great for keeping insulation in place to maintain its insulating properties — an essential feature for maintaining energy efficiency in your home or business.

Different Techniques for Applying 30lb Felt Staples

If you want to attach 30lb felt, you must know the right size staples. Luckily, you can use a few techniques; each requires different-sized curved staples.

Manual Staples

The most commonly used staples for manual applications are 5/16” or 1/4” staples. These curved staples will be able to penetrate deep enough into the material and provide a good structure for your project. 

Their extra curve gives them more support than regular straight-in variety of staples.

Arrow T50 Staples

Arrow T50 has become the staple for attaching 30lb felt with a manual stapler, such as the Arrow Fastener T50. It’s durable, robust, and can easily shoot through 30lb felt. 

Furthermore, its staple range is 1/4” up to 9/16”, meaning it can handle everything from medium-duty materials to a 2-ply fabric.

Electric Stapler

For bulk projects like a building wrap or large structures that need to cover an entire wall or roof, an electric stapler is your best bet—you won’t have to worry about reloading every few minutes like a manual stapler! 

The most commonly used electric staples are 5/8″ or 3/4″. A larger size will allow more penetration into the material since heavier fabrics require more pressure to keep them in place—so 5/8″ or 3/4″ should ensure that your project stays secure and undamaged over time.

Pros and Cons of Using 30lb Felt Staples

Now that you know what size staples you need for 30lb felt, let’s review the pros and cons of using this weight-grade felt when stapling.


The main benefit of using 30lb felt is that it offers superior soundproofing capabilities due to its density. 

This means that nail pops, creaking floors, and other noises are significantly reduced—something your neighbors will thank you for. 

Additionally, 30lb felt can also act as an effective barrier against moisture and cold air, helping to keep your home warm in the winter and cool in the summer.


That being said, 30lb felt staples have some drawbacks — mainly cost and installation time. 

The extra layers of material used in higher-grade felts can make them more expensive than lighter options, and installation can be quite time-consuming due to the thickness of the material. 

Additionally, overdriving the staples can lead to tearing or damage, which can result in additional costs for repair.


When deciding what size staples to use for 30lb felt, you must consider the project you are working on, the available tools, and the types of staples you can use. 

If unsure of the best size, start with a small staple to under gage the material for a secure fit. If that isn’t enough, increase the size or switch to a heavier-duty staple.

Ultimately, the size of the staple you use will depend on what type of felt you are working with and the needs of your particular project. 

With these guidelines under your belt, you’ll soon be able to determine the best size staples for 30lb felt and complete your project quickly!
