The standard measure for most pierced earlobes intended for conventional jewelry is 20 gauge (20G), which equates to approximately 0.8 millimeters in diameter. This size is generally accepted as the starting point for many initial ear piercings and is compatible with a wide variety of commercially available earrings, from studs to small hoops.
Adhering to this initial size offers several advantages, including ease of healing and reduced risk of complications like tearing or infection. Throughout history, consistent sizing has simplified the jewelry production process, allowing manufacturers to create earrings that fit a majority of the population comfortably and securely. Maintaining a consistent gauge facilitates the effortless exchange of jewelry across various styles and designs.
