An 8-gauge wire is larger than a 14-gauge wire, at 0.1285 inches in diameter compared to 0.0641. This is because in the AWG system, the thicker a wire is, the lower the gauge number.

American wire gauge (AWG) is a system of numerical designations of wire diameters where the thicker and less resistive the wire is, the lower the gauge number. More often than not, we’ve seen ...

The best speaker wires come in various gauges; as the AWG (American Wire Gauge) number decreases, the size of the wire increases. For example, a 12 AWG wire is bigger than an 18 AWG wire.
