Why do we use Gauge?

March 04, 2021


Why are sheet metal and the tubing made from it measured in Gauge?

Like many things, there is a long story here.

It starts with producers of metal wire in England. The number known as Gauge was the number of times the wire had been drawn to make it thinner. This explains why higher Gauge numbers mean thinner material.

After some time, these numbers were standardized as Manufacturers Standard Gauge.

The most common Gauge sizes are:

Gauge Thickness
(in inches)
10 .1345
11 .1196 (~1/8)
12 .1046
14 .0747
16 .0598 (~1/16)
18 .0478
