Here at SparkFun, we typically use 22 AWG wire for prototyping and breadboarding. When using a breadboard or PCB, solid core is perfect because it fits nicely into the holes. For other prototyping/building involving soldering, the stranded core is #1, just be sure not to let too much current run through a single wire.
20 Gauge Primary Wire - 100 Feet. Primary wire is commonly used in automotive and general electrical applications. 20 gauge wire from Del City is the ideal choice for a variety of applications include unique projects, original equipment, or replacements.
A 20 gauge wire works well for most jewelry-making needs, such as wire-wrapping, but you can go with a finer gauge, such as 21, 22, or 24 for smaller more delicate beads and stones.
All you need to do is place your piece onto the steel block and use a hammer to gently tap the piece until it hardens. A rawhide mallet is great to use as it won't damage your work, a chasing hammer on the other hand will flatten your work slightly as well as harden it.
With earrings, 20-22 gauge is perfect. I like to work with thicker wires because they hold their shape so well, so my first choice would be 20 gauge silver wire.

What is the smallest size gauge? A standard ear piercing is 20g or 18g so the smallest gauge size is 20g. Gauge sizes are always even numbers and the smaller the number the bigger the earring, so from 18g the next size up would be 16g.

AWG is American Wire Gauge. So no, there's no difference. It's just a standardized way to express thickness. 1 of 1 found this helpful.

What is Wire Gauge? The thickness of a cable or wire is defined by its gauge size. The general rule of thumb is that the smaller the gauge number, the thicker the cable.

using larger wire will not hurt anything or cause any overload. The larger wire will cost more, the pathway or where it has to fit, and the physical size of the connecting means (ie. the size of terminal or clamp it has to fit in), will all be determining factors in just how big is too big.
The smaller the gauge, the larger the diameter of the wire. The larger the diameter of a wire, the less electrical resistance there is for the signals it carries. For long runs with more potential damage, the 24AWG Ethernet cable is the best, because it comes with stronger conductors with lower attenuation.
While the higher AWG in slim Ethernet cables limits the length of the cable you can run without creating resistance, these cables are beneficial for high-density networks and data centers, as well as a lot easier to install and manage.
20 gauge: Medium thick wire. 22 gauge: Medium wire.
In general, a lower AWG number is better than higher AWG. Since these electrical signals are usually low power, smaller AWG (larger wire) is not needed. In these situations, proper shielding and cable-pair twisting is more important for signal integrity than the AWG of the strands.
19 gage is heavier than 23 gage, 19 gage is thicker.

the lower the number the thicker the wire. it's a measurement called gauge, which seems backwards but isn't, a size measurement used for metal thickness: lower number = thicker metal and higher number = thinner metal.
Speaker wires that are anywhere between 12 to 16 gauge are most commonly used for connecting speakers to an amplifier or an Audio/Video (A/V) receiver. A lower-gauge number indicates a thicker wire, while a higher-gauge number indicates a thinner wire.
24 gauge jewelry wire is a good all-purpose wire diameter. If you use half-hard wire (or you work-harden dead-soft wire), then 20-gauge wire is also sturdy enough to hold its shape for making handmade chain, ear wires, eye pins, jump rings, and lightweight clasps.
18-gauge are used for low-voltage lighting and lamp cords in 10 amps. 16-gauge are used for light-duty extension cords supporting 13 amps. 14-gauge are usedfor light fixtures, lamps, lighting circuits with 15 amps.
U.S. manufacturers express the thickness of metal panels as their 'gauge', with 22-gauge being the thickest and 29-gauge the thinnest of traditionally-sold metal roof and wall panels. This means that while a 26-gauge panel from one manufacturer could measure 0.027 in.
To make delicate jewelry, use 30-gauge or 28-gauge wire (0.25 to 0.32 mm). It is perfect for weaving wire, loops, working with beads, and making small chains. This gauge uses fine jewelry making materials.
