Common Piercing Type
“For piercings in general, 18 g through 16 g is the most common. For nipple or naval piercings, 14 g through 12 g is most common. For larger gauges—like stretched ear lobes—the smallest gauge usually starts at size 8 and goes up from there.”
In this manner, is 18g smaller than 16G?
Though it seemingly goes against logic, earrings and other jewelry gauge sizes actually get bigger the lower the number of the gauge. An 18 gauge, one of the smallest gauges, is actually smaller than a 16 gauge earring, with the largest gauges being 0, 00, and 000 gauge jewelry.
Regarding this, can I put a 20G in a 16G piercing?
yes you can. When learning about piercings sizes you will know that the bigger the number the smaller the gauge of the piercing so yes you may use an 18g. the 18g is smaller than the 16g. Just be aware though that sometimes user smaller jewelry could cause your jewelry to get accustomed to that size.
