What You'll Learn

The gauge of a nail refers to its thickness
There are, however, some misconceptions about what gauge means. Some people think that the gauge is equal to the number of nails per inch. This is incorrect, but it does follow that the more pins there are to the inch, the finer the pin.
It's important to use the right gauge for the job. For example, installing doors, crown moulding, fine trim, or assembling cabinets each require a certain size of nail referred to as a gauge. The most common gauge sizes are 15, 16, 18, 21 and 23.

The higher the gauge number, the thinner the nail
The gauge of a nail refers to its thickness and therefore its holding power. The higher the gauge number, the thinner the nail. For example, 15- and 16-gauge nailers are the most versatile for interior carpentry. The higher the number, the thinner the nail; the lower the number, the thicker it is.
Gauge sizes are the thickness of the nail, and a higher number means a thinner nail. The most common gauge sizes are 15, 16, 18, 21 and 23.
It's important to note that the gauge is not equal to the number of nails per inch. While it's true that the more pins to the inch, the finer the pin, this doesn't mean that the gauge is equal to the number of nails per inch.

The gauge of a finish nail is a measure of its diameter
Gauge sizes are essentially the thickness of the nail. The most common gauge sizes are 15, 16, 18, 21 and 23. The right nailer is important for getting the best results, whether you're installing doors, crown moulding, fine trim, or assembling cabinets.
The gauge of a nail is also a measure of its holding power. As the gauge number increases, the thickness decreases. One source suggests that the gauge is equal to the number of nails per inch, so the more pins to the inch, the finer the pin.

The most common gauge sizes are 15, 16, 18, 21 and 23
The gauge of a nail refers to its thickness, and therefore its holding power. The higher the gauge number, the thinner the nail. The most common gauge sizes are 15, 16, 18, 21 and 23. These are the most versatile for interior carpentry, such as installing doors, crown moulding, fine trim, or assembling cabinets.
The 15- and 16-gauge nailers fire nails up to 2-and-a-half inches long. However, the right nailer for the job will depend on the application. For example, a 15-gauge nailer is recommended for installing doors, while an 18-gauge nailer is better for fine trim.
It's important to note that despite the small differences in gauge sizes, one size does not fit all. The best results will be achieved by using the right nailer for the specific application.

The gauge of a nail gun refers to the thickness of the nails it uses. The higher the gauge number, the thinner the nail. For example, 15- and 16-gauge nailers are the most versatile for interior carpentry. The gauge of a finish nail is a measure of its diameter, just like an electrical conductor. The higher the number, the thinner the nail; the lower the number, the thicker it is.
The gauge is also equal to the number of nails per inch. The more pins to the inch, the finer the pin. For example, 15, 16, 18, 21 and 23 gauge are common sizes, with 15 being the thickest and 23 being the thinnest.
It's important to use the right nailer for the job. Installing doors, crown moulding, fine trim, or assembling cabinets each require a certain size of nail referred to as a gauge.
