The standard measurement for the thickness of earring posts intended for initial piercings and commonly sold earrings is typically 20 gauge (20G). This corresponds to a diameter of approximately 0.8 millimeters. This sizing facilitates comfortable insertion into newly pierced ears and is generally compatible with a wide range of earring styles and designs available commercially.
Adherence to this particular dimension helps ensure that individuals can readily acquire and wear earrings without requiring stretching or modification of the piercing. It also contributes to minimizing the risk of irritation or discomfort associated with using posts that are significantly thicker. Historically, this gauge has evolved to become the accepted norm, striking a balance between visibility, durability of the post, and ease of use.
