Question: what gauge are most earrings?
Answer: Any standard size earring or post will fit you. If you've been pierced with a needle in a piercing shop, most likely you're at a 20 or 18 gauge. No worries! The smaller the gauge the bigger the hole, so any standard size earring can be worn in addition to 20 or 18 gauge captive rings, cartilage studs, etc.
