Wire Gauge Size report
Wires have different specifications, and each specification is suitable for various purposes. The specification of a wire refers to its thickness. A number represents each specification, the smaller number indicates the thicker wire gauge, and the higher number means the thinner wire.
American Wire Gauge is a standard method developed in the United States to measure and identify conductive wire cables' thickness. The AWG chart is suitable for specifying the specifications of round and solid wires made of non-ferrous metal.
The AWG value of a twisted pair is determined by the total cross-sectional area of all wires. Because there are always some gaps between the twisted pairs, the diameter of the twisted pair is always slightly larger than the diameter of a single wire for the same AWG value. In the following article, we outline what wire gauges are and available standard wire gauge sizes.
What Is The Wire Gauge
American wire gauge is a standard for distinguishing wire diameter, also known as Brown & Sharpe wire gauge. This standardized wire gauge system has been used in the United States since 1857. The AWG value is a function of wire thickness (in inches).
The AWG value is inversely proportional to the size of the wire diameter. The smaller the value, the thicker the wire diameter, the greater the current that can be carried, and the longer the number of meters transmitted, but the corresponding price is more expensive.
The HDMI limit transmission length of different wire gauges is basically between the following values:
Wire Gauges | Limit Transmission Length |
---|---|
30 AWG | 5-8 m |
28 AWG | 12-15 m |
26 AWG | 18-20 m |
24 AWG | 20-25 m |
Wire Gauge Size Chart
American Wire Gauge standards range from 0000 (which can handle up to 302 amps) to 40 (up to 0.0137 amps). Most household and commercial wiring demands range from 2 (95 amp maximum) or 3 (85 amp maximum) to 14 (15 amp maximum). You can check the following wire gauge size chart to know more about the AWG cable sizes and their unique properties.

Applications for Different Wire Gauges
When selecting an electrical wire for an application, the wire gauge is an important design consideration. The wire gauge imparts more than information about the thickness of a wire. As each wire gauge carries different physical and electrical properties, they are generally suitable for various purposes. Thinner gauges usually find application in more lightweight applications, while thicker gauges are employed for heavy-duty applications. The following are some common use cases for different wire gauges.
Wire Gauges | Uses |
---|---|
Gauge 4 | furnaces and large heaters |
Gauge 6 | kitchen cooktops and ranges |
Gauge 10 | clothes dryers, large AC units, and water heaters |
Gauge 12 | residential outlets and small AC units |
Gauge 14 | lighting fixtures, devices, and circuits |
Gauge 16 | light-duty extension cords |
Gauge 19 | low-voltage lighting and cords |
