Sheet metal gauge size chart gauge or gage sizes are numbers that indicate the thickness of a piece of sheet metal with a higher number referring to a thinner sheet. The table below shows the actual thickness of sheet steel in millimetres and inches compared to gauge size. This is known as the manufacturers standard gage for sheet steel. For a more comprehensive gauge chart you can check out our sheet metal gauge chart here.

There are several different gauge systems used today with specific gauge designations used for specific metal types. Gague are used to specify the thickness of a metal sheet. The thickness of sheet metals is specified by gauge. As the gauge number increases the material thickness decreases.

The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. Converting sheet metal gauge numbers to millimeters is as simple as following the chart below. These dimensions vary slightly between different materials such as stainless steel and aluminium but should be accurate enough for most everyday purposes. Typically the even number gauges are used more frequently.

Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. For other materials such as aluminum and brass the thicknesses will be different. For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick.
