Which gauge has the larger diameter: 14 or 21?

Explanation:
Gauge size is inversely related to diameter: the smaller the number, the thicker the diameter. As you increase the gauge number, the diameter gets smaller. So the gauge with the smaller number has the larger diameter. In this pair, the smaller number corresponds to the larger bore, so 14 gauge has a larger diameter than 21 gauge. This difference matters in practice because a larger bore allows faster fluid flow but is more invasive.
