Navigating the world of piercings can be daunting, especially when it comes to understanding the different sizes and measurements involved. That’s where a comprehensive mm size chart comes in handy. In this blog post, I’ll provide you with everything you need to know about mm size charts, including their uses, how to read them, and specific charts for different types of piercings.

What is a MM Size Chart?

A mm size chart is a table that converts the diameter of a piercing in millimeters (mm) to its corresponding gauge size. Gauge size refers to the thickness of the jewelry, with lower numbers indicating thicker jewelry.

How to Read a MM Size Chart

Reading a mm size chart is simple. Locate the diameter of your piercing in the left-hand column and follow the row across to find the corresponding gauge size. For example, a piercing with a diameter of 1.6mm would be a 14-gauge piercing.

MM Size Charts for Different Piercings

Different types of piercings have different standard sizes. Here are some common mm size charts for various piercings:

  • Earlobe Piercings: 1.6mm (14g) – 2.4mm (12g)
  • Cartilage Piercings: 1.2mm (16g) – 1.6mm (14g)
  • Nostril Piercings: 1.6mm (14g) – 2mm (12g)
  • Septum Piercings: 1.6mm (14g) – 2.4mm (12g)
