The gauge number of wires gets smaller as the diameter gets larger. Every sixth gauge indicates a doubling of the diameter. For instance, a 6-gauge wire is 0.162 inch, or double that of a 12-gauge wire. One of the largest, 0000-gauge wire, is 0.46 inch in diameter. One of the smallest, 32-gauge wire, is 0.008 inch wide.
