Why You Need the International Ring Size Chart
When you shop for rings from different countries, the sizes aren’t always the same. A size 7 in the U.S. is not the same as a size 7 in the UK. That’s why you need to know how to switch between different size systems. It saves you from buying a ring that’s too tight or too loose.
Different Ring Sizing Systems
Different countries follow different sizing conventions. Here are some of the most common:
- United States & Canada: Numeric sizes (e.g., 5, 6, 7)
- United Kingdom: Alphabetic sizes (e.g., H, J, K)
- Europe: Numeric with circumferences (e.g., 50, 52, 54)
- Japan: Similar to the US but usually smaller sizes
- Australia & New Zealand: Alphanumeric sizes (e.g., M1/2, N1/2)
- India: Numeric based on a different scale
