What is a Gauge in Jewelry?

A Gauge is a wire usually made out of copper which is used in making Jewelry. Aluminum, brass and nickel are some other material popular in making Jewelry – Gauge to mm to Inch

A Gauge is a thin, cylindrical-shaped elongated strand of wire. It is folded and bent using pliers during the Jewelry making process.

During the early days, all the wires were round. Now there is a variety of wire shape available in the market. You can now get around a cross-sectional area in a wire. Square, half-round, oval are some other cross-sectional area available in wire these days.

The square wire gives a beautiful finish to the piece of Jewelry. It can also be twisted to make some amazing visuals and designs- Gauge to mm to Inch

Wire Size – Gauge to mm to Inch

Different Gauge sizes are needed for different pieces of Jewelry. The commonly used Gauge size is 12-18 in Jewelry making. The size of the wire Gauge is determined by two standard measurements system these are the ‘American Wire Gauge’ and the ‘Standard wire Gauge’.

According to both these measurement systems, the size of the gauze is smaller with the increasing number on these standard scales.

Jewelry type	Gauge	Millimeter (mm)
Jump rings Bracelets Necklace Earrings	10-18 16-18, 20 16-18 18 or 20	2.5 to 1.3 1.3 to 0.88 1.3 to 0.88 1.0 to 0.8

Choosing the right wire Gauge for your Jewelry is an important deal. You want to choose the right wire for the particular type of Jewelry you are planning to make.

The material of the wire is another necessary detail you can’t miss out – Gauge to mm to Inch

Pick your Gauge based on the type of Jewelry you are making. We have mentioned above the perfect Gauge size for various Jewelry. Once you know the Gauge measurements for your Jewelry type then it is relatively easy to pick the right Gauge.

Here is a step to step guide on how to choose the correct wire Gauge for the Jewelry you are making – Gauge to mm to Inch

• Choosing the wire Gauge size
• We know that different Jewelry pieces require wires of a different Gauge. You cannot make a ring with a wire of high thickness or necklaces with a wire extremely thin.

1. For Delicate Jewelry

For making delicate Jewelry wire Gauge of size 30-Gauge to 28- Gauge is perfect. It is important to note that the larger the Gauge reading on the measurement scale, smaller is its thickness.  30-Gauge to 28-Gauge in terms of millimeters are around 0.25 to 0.33 mm. this makes them extremely thin wires. These are perfect for making earrings and rings. You can also use this wire in knitting and crochet making. If you are going with a wire this thin, then make sure your tools have a very sharp and thin needle. This will resist any damage to the wire and will be easier to use – Gauge to mm to Inch

2. For Beading Jewelry

When the type of Jewelry you are making includes beads, then, the wire Gauge size changes. For beading with string Jewelry type, you have to choose a wire with Gauge of value 26-Gauge and around. In millimeters reading it is 0.40 mm wire, which is a thin wire. This is the perfect size of wire for stringing very small beads. This wire can also be used in the process of knitting and crochet. With this sized wire, you can make also join beads and stones together to make headpins – Gauge to mm to Inch

3. For Pendants

For pendants and necklaces, you don’t want your wire to be very thin, that will lead to breaking of the wire. So, this type of Jewelry requires wires relatively thicker. The 22-21-Gauge wire is the perfect size for making pendants and necklaces. When converting this into millimeters, we get a 0.64 to 0.75 mm wire. This is a wire of medium thickness. You can use this wire with beads and crystals to make your pendants. When you are using a wire of this thickness, you don’t have to go with the very sharp tools. The normal pliers and tools work perfectly with this wire.

It is important to note here that before you choose any wire make sure, it can fit through the beads and crystals you have chosen. If the wire is not able to fit through the holes, then you can either pick different beads or the wire of different Gauge – Gauge to mm to Inch
