The first factor we will be discussing regarding the 16-gauge vs 18-gauge brad nailer is the size. The gauge size of the nailer also represents the size of a nail.

The second differentiating factor between 16-gauge and 18-gauge brad nailer is the task. Both the brad nailers are used for different purposes. If you want to do heavy-duty tasks such as driving nails to install baseboards or shiplap then a 16-gauge nail is the best choice where 18-gauge nailers are used for light work like finishing or nailing around the house. Also, an 18-gauge nail is used at small places or thin wood so it does not break or cause any damage.


The next factor we will use to differentiate between 18-gauge and 16-gauge nailers is the intensity of driving nails into the wood or place. There are two types of trims; exterior trim and interior trim. If you want to use nailer on exterior trim then we will recommend you to go with the 18-gauge nailer while 16-gauge nailer will prove to be a good option for interior trim. Interior trim requires more stability and grip so a 16-gauge nail with a bigger diameter as compared to an 18-gauge nail can provide you the strength you are looking for.


The last factor that creates a difference between a 16-gauge brad nailer and an 18-gauge brad nailer is the finish. Finishing is defined as the smoothness of a surface after installation or framing nails. Concerning the finished matter, the best choice you can make is the 18-gauge nailer because the thin circumference and smaller head of the 18-gauge nail are not as much visible as a 16-gauge nail.
