The standard size for a navel piercing, referring to the thickness of the jewelry’s post, is typically 14 gauge (1.6mm). This measurement dictates the initial size of the piercing hole, and is a crucial consideration for both the piercing professional and the individual receiving the piercing. A larger gauge denotes a thicker post, while a smaller gauge signifies a thinner one.
Employing the correct size during the initial procedure promotes proper healing and reduces the likelihood of migration or rejection. A gauge that is too small can increase the risk of the jewelry cutting through the skin, while a gauge that is too large may cause unnecessary trauma to the tissue. Historically, proper gauging has been a cornerstone of safe and successful body modification practices across various cultures.
