What is 22 gauge wire used for?
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.
What size is 30 gauge wire?
AWG Wire Sizes

Gauge | Diameter | |
---|---|---|
27 | 0.0142″ | 0.3607mm |
28 | 0.0126″ | 0.3200mm |
29 | 0.0113″ | 0.2870mm |
30 | 0.0100″ | 0.2540mm |
How do I choose a wire size?
To determine what gauge wire you need, consider the carrying capacity and the amount of current the wire needs to conduct (measured in amperage or amps). Wire gauge is directly related to how many amps you need to run through it. The distance you need the wire to go can also impact the gauge of wire you need.
How do I calculate what size wire I need?
How do you determine cable wire size? Divide the voltage running through the cable by your target current. If, for instance, 120 volts will act on the cable, and you want 30 amps to run through it: 120 / 30 = 4. This is your target resistance, measured in ohms.

What gauge of wire is thicker?
Gauge Thickness chart & Information:
Gauge -Thickness | Dimension inches thick | NOTES |
---|---|---|
10 | .102 inch | |
12 | .081 inch 50 | About as thick as a standard wire coat hanger |
14 | .064 inch a bit thicker than 1/16 inch | This and thicker is Considered PLATE METAL in sheet metal. as in “copper plate” |
16 | .051 inch |
What does gauge mean for wire?
thickness
The gauge of a wire refers to its thickness. Each gauge is represented by a number, with smaller numbers representing thicker wire gauges and higher numbers signifying thinner wires.
Which is thicker 20 gauge or 22 gauge?
20 gauge is thicker wire than 22 gauge.

Which wire is best for home wiring?
If what you need the wire for is the wiring of your home, copper wires will be most appropriate for you. Copper is more conductive than aluminum but is also heavier and more expensive.
