Nailers of sizes 15 gauge, 16 gauge, and 18 gauge are suitable for most baseboards, although there can be differences in what you choose based on the thickness of the baseboard. The length of the nails that you use the nailers with should also be around 2 inches.
Since nailers are power tools that will help you insert the nails into the baseboard, you will need to be careful about the power that you actually exert to maintain the structure and integrity of the baseboard and its surrounding structures.
There are several considerations that go into the size of the nailer you should use for baseboards. The following guide will help you get more clarity about this so that you can make your decision.
Why You Should Choose the Right Size
Choosing the right size of nailer for your baseboard is extremely important. Since nailers house and insert nails of compatible sizes, choosing the size of the nailer essentially implies choosing the size of the nail you will be inserting.
Opting for extremely big or small nailers and nails will compromise the baseboard’s look and function while also causing damage to other associated fixtures and elements.
For instance, if the nails are too big for the baseboard, this could result in the following.
Either of these can cause damage to these other structures. On the other hand, using extremely small nails can lead to:
What Size Nailer for Baseboards Should You Use?
There are nailers and nails of various sizes, which makes opting for the correct size often makes for a challenging endeavor and undertaking. In this case, the best way to opt for a suitable nailer is by taking note of the nail gauges that work well with the nailers.
The perfect nail size for baseboards will help you secure the structure better without going too deep into the wall. The following three sizes are some of the options that you should consider.
|Nail Gauge||Characteristics||Ideal Elements||Ideal Application|
|15 Gauge||Thickest and strongest nail size suitable for large and heavy baseboards.||Ideal for baseboards made of thicker materials, such as hardwood or MDF.||Best for more extensive and heavier baseboards where maximum holding power is required.|
|16 Gauge||A versatile nail size suitable for most baseboards.||Can be used for most types of baseboards, including thinner and lighter ones.||A popular choice for most baseboard installations due to its versatility and holding power.|
|18 Gauge||The thinnest nail size is suitable for thinner and lighter baseboards.||Best for baseboards made of lighter materials, such as pine or PVC.||Ideal for smaller and thinner baseboards where a more discreet nail is desired.|

Nailers of 15 gauges are pretty popular for baseboards. However, you will also need to account for the size of the baseboard to ensure that you can use these nailers without too much hassle.
For baseboards that have a relatively more significant thickness level, these nailers will help provide the necessary support by allowing the nails to penetrate the baseboard and wall deep enough. Thicknesses between ¾ inch to a little over 1 inch are the best receivers for finish nailers of 15 gauges.
Due to the larger size in this case, you will find it easier to work with otherwise tricky structures. The stronger force and power will allow you to pierce the wall with the nails in a convenient manner. Additionally, many nailers of this size include shaped guns allowing you to access the structure’s remote corners.

Nailers of 16 gauges are practical if your baseboards are a bit smaller in size. The nails that these nailers accept are also smaller, thus making it possible for them to enter the baseboards and wall frameworks up to the required extent without being too much or too little.
Generally, baseboards just a little smaller than the previous option can take the force of the 16-gauge nailers properly. This means that if your baseboards are between ½ an inch and ¾ of an inch, the smaller nails of this nailer will work better here.
Being smaller, these nailers are also a bit light in weight. This removes the issue of lugging them around since they are quite easy to handle and use. The speed with which they work is also higher.
Nailers with a size of 18 gauges are also extremely popular when it comes to inserting nails into structures. This makes them valuable to keep around if you want to work with smaller structures around the house, such as caps, molds, trims, and more. They are also suitable for particularly thin baseboards.
However, it is usually rare for baseboards to be thinner than ½ an inch, which is why there is a bit of incompatibility between this size and its use on baseboards. However, if you find certain baseboards in your house that are actually relatively thin, it will be well worth it to use 18-gauge nailers.
For such nails, however, you will also need to find an efficient enough nailer to do the trick. Brad nailers are usually the best choice since they will help you hold the nails and release them quickly without too much effort on your part.

Length of Nails
How long the nails are is vital to keep in mind here so that they penetrate the baseboard and wall to just the right extent. Usually, the length of nails is expressed with a ‘D’ next to a certain number, such as 2D, 3D, 4D, 8D, etc.
When it comes to the length of nails suitable for baseboards, you should ideally use nails measuring a maximum of 8D or 2.5 inches in length. Keeping the nail length to around 2 inches is a good idea for baseboards in order to correspond to their own thickness.
However, for thinner baseboards, it is possible to opt for shorter nails that are around 1.5 inches in length. This should be enough to pass through the baseboard while also finding a stud in the wall’s framework for security, thus avoiding the possibility of interrupting and damaging other structures.
How to Install Baseboards With Nail Gun
Installing baseboards or even crown molding is an important step in creating a finished look for any room. Using nailers is a fast and efficient way to attach baseboards to walls.
With the right tools and techniques, you can achieve a professional-looking result in no time.
Here are the tools and materials you will need for installing baseboards using nailers:
Step 1: Prepare the surface for installation
Before installing the baseboards, ensure that the surface is level and free from any debris or obstructions that may affect the installation. Sand the surface if needed to make it as smooth and level as possible. This will help ensure that the final result looks uniform and consistent throughout its structure.
Step 2: Use the proper safety equipment
It’s important to wear the right safety equipment when using a nailer. Gloves and goggles protect your hands and eyes from potential injuries due to the power and sharpness of the nails. Earplugs can also protect your ears from the loud noise of the nailer. A mask can protect you from dust and debris, especially if you’re sanding the surface.
Step 3: Measure and cut the baseboards to fit
Measure the baseboards against the wall to ensure they fit properly. Use a saw to cut the baseboards to the correct length and shape. If necessary, cut any excess bits before installation.
Step 4: Load the nailer and turn it on
Load the nailer with the correct nail size and turn it on. Be sure to follow the manufacturer’s instructions for proper use. Ensure that the nailer is loaded with nails that are the right size and length for the baseboards being installed.
Step 5: Attach baseboards to wall with nailer
Hold the baseboard against the wall, and using the nailer, drive nails into different sections of the baseboard until it is securely attached to the wall. Aim for around 13-14 inches between each nail, although you may need to adjust based on the size and weight of the baseboard. Start from one end of the wall and work your way towards the other, ensuring that the baseboard is flush against the wall as you go.
Step 6: Cover nails for smooth finish
To create a seamless finish, apply paste or binder over each nail to cover them. Spread it evenly over each nail and the surrounding area to create a smooth finish. Allow it to dry completely before sanding.
Step 7: Sand and paint for seamless look
Once the paste or binder has dried, lightly sand the surface to ensure a seamless finish. Use a fine-grit sandpaper and sand in the direction of the wood grain. Wipe away any dust with a cloth. If desired, paint the entire baseboard to match the decor of the room.
By following these steps, you can easily install baseboards using nailers and ensure a professional-looking finish.
Baseboards Nail Size FAQs
Why Do I Need Nailers for Baseboards?
Nailers are important for baseboards to maintain the wall’s structural integrity while also ensuring that they remain in place for a long time.
Although baseboards are usually easy to install, nailers will help properly drive the nails in, even with other methods.
Can I Use a 20+ Gauge Nailer on Baseboards?
A nailer or pinner with a 20+ gauge size is not typically suitable for baseboards due to the highly tiny nails that it tends to house and manage.
It might be best for you to avoid this size and use it only for smaller projects, such as picture frames or small DIY furniture projects. Typically, using a larger nail size, such as 15 or 16 gauge, can help provide the necessary holding power for a secure installation.
Why Are Nails Used for Baseboards So Small?
Nails used for baseboards tend to be extremely small due to the size of the baseboards themselves.
One of the main reasons for installing baseboards is to improve the look of the wall. Big nails can end up standing out too much, which is why the nails need to be small, with the nailers being made to be compatible.
The Bottom Line
Selecting the right gauge level is crucial when it comes to installing baseboards. Opting for 15-gauge or 16-gauge nailers is recommended, but 18-gauge nailers can still work well in many cases. Remember, the gauge level determines the size of the nails the nailer can hold, so make sure to choose the appropriate size based on the size of your baseboard.
To ensure stability and durability, it is important to consider both the baseboard’s size and the nails’ length. By following these guidelines, you can ensure a smooth and successful baseboard installation project.
