The standard size for initial daith piercings is typically 16 gauge (1.2mm). This refers to the thickness of the jewelry used to create and adorn the piercing. As an example, a ring or curved barbell inserted into the daith during the initial piercing would commonly be 1.2mm in diameter.
Selecting the appropriate jewelry size is crucial for proper healing and minimizes the risk of complications. A properly sized piece of jewelry helps maintain the integrity of the pierced tissue, encourages blood flow, and avoids undue pressure. Historically, choosing the correct size has been a cornerstone of successful piercing practices, contributing to both comfort and aesthetic appeal.
