The smallest AWG size is 40 and the largest is 0000 (4/0).

AWG general rules of thumb – for every 6 gauge decrease, the wire diameter doubles and for every 3 gauge decrease, the cross sectional area doubles..

What is 18 AWG wire used for?

It’s primarily used in commercial applications to power hardwired light fixtures in ceilings and walls. It’s more flexible than THHN building wire but less resistant to heat, and it is only available in limited gauges (18 and 16 AWG).
