When shopping for rings, understanding how the ring size conversion from letters to numbers works is essential. Ring sizing systems vary by country, region, and even jeweler, which can make buying rings online or internationally confusing. Whether you are purchasing a ring for yourself, ordering a surprise gift, or comparing international jewelry sizes, getting the correct size ensures comfort, wearability, and long-term satisfaction.
This in-depth guide explains how ring size letters convert to numbers, how different sizing systems work, and how to accurately measure your ring size. You’ll also learn how to avoid common sizing mistakes and use reliable tools to ensure a perfect fit every time.
Understanding Ring Sizes Across Different Systems
Ring sizes are not universal. Instead, they are expressed using letters, numbers, or circumference measurements, depending on the country. This variation is the primary reason conversion charts are so important.
Some regions rely on alphabetical sizing, while others use numerical values. If you’re shopping internationally or browsing online marketplaces, understanding these systems can prevent costly resizing or returns.
If you’re new to ring sizing, it’s helpful to start with a comprehensive overview of how sizing systems work globally. You can explore this further on the official ring size calculator resource, which breaks down sizing standards in detail.
Ring Size Letters Explained (UK & European System)
In the UK and several European regions, ring sizes are denoted by letters instead of numbers. This system typically starts at A for very small sizes and progresses through the alphabet as the ring size increases. Half sizes are represented using increments such as A½, B½, and so on.
Each letter corresponds to a specific inner circumference and diameter. As the letters increase, so does the ring’s size. At the upper end of the scale, sizes may extend beyond Z into variations such as Z+1, especially for custom or specialty rings.
Because this system differs significantly from the US numerical scale, conversion is often required when ordering internationally. For a deeper breakdown of cross-border sizing, refer to this detailed guide on UK-to-US ring size conversion.
Ring Size Numbers Explained (US & Canada)
In the United States and Canada, ring sizes are measured using numbers, typically ranging from size 0 upward, with half and quarter sizes available for precision. This system offers more granular sizing, which many people find easier to understand.
For example:
- US size 5
- US size 5.5
- US size 6
Because US sizes increase in consistent increments, they are often easier to convert from measured finger circumference or diameter.

Ring Size Conversion: Letters to Numbers
Converting ring sizes from letters to numbers requires a reliable conversion chart. While charts may vary slightly by manufacturer, the following conversions are widely accepted:
| Ring Size Letter (UK) | Ring Size Number (US) |
| A | 0.5 |
| B | 1 |
| C | 1.5 |
| D | 2 |
| E | 2.5 |
| F | 3 |
| G | 3.5 |
| H | 4 |
| I | 4.5 |
| J | 5 |
| K | 5.5 |
| L | 6 |
| M | 6.5 |
| N | 7 |
These conversions are useful for everyday purchases, but for high-value jewelry such as engagement or wedding rings, exact measurement is strongly recommended.
