Apple’s installation guide ↗Best age to let him pierce his ears? 15? wait til 18?
Scan with your phone’s camera.
Most teens around here seem to be getting their ears pierced between fifteen and seventeen. Judging by this I would say, maybe, sixteen. If he is going to get his ears gauged, however, make sure he really wants it because it looks pretty painful.
... Sometimes having a stud in each ear is considered to be pretty safe.
I would suggest going to a mall or place where you would see an abundance of teens to see what they're doing in your area. While this is the fashion here, it can be considerably different where you live.
