How Thick Is 11 Gauge Aluminum?

Gauging Aluminum Thickness

Understanding the thickness of aluminum is crucial for a variety of applications. Different projects require different thicknesses. The term ‘gauge’ often pops up at this point.

Gauge is a measurement that relates to the thickness of aluminum sheet. Each gauge number corresponds to a standard thickness.

Let’s delve into the origins of the gauge system and provide a handy chart to convert gauge to actual thickness in inches and millimeters.

Aluminum Gauge System Origins

The gauge system originated from the number of times a metal had to be passed through a press to reach a desired thickness. The more passes, the thinner the metal, hence the higher the gauge number.

With aluminum, the gauge system can be a bit confusing because it doesn’t correspond directly to thickness in inches or millimeters. Understanding the gauge system is essential for choosing the right thickness for your project.

Gauge To Thickness Chart

A gauge to thickness chart is an invaluable tool to make sense of the non-intuitive gauge system. Below is a chart that converts aluminum gauge numbers into inches and millimeters.

Note that the chart is specific to aluminum and cannot be used interchangeably with other metals due to differing densities and standards.
