What is the Definition of Gauge?
Gauge is a measurement of the thickness of something, be it beads, wire, thread, or needles. Generally, smaller numbers indicate thicker sizes. Wire gauges ranges from 10 (very thick) to 28 (very thin). Seed bead gauges are written as fractions, like 6/0 (~3.7mm) to 15/0 (~1.5mm). Size 11/0 seed beads are the most common. Thread does not have a standard gauging system, leaving each manufacturer to invent their own.
