Find Your Perfect Fit
We use standard international sizing. Below is a quick reference for the most common systems. If you are between sizes, we recommend choosing the larger size for wider bands.
Choosing the perfect ring starts with knowing your exact size. However, ring sizing systems can vary depending on the country. In this article, we’ll explain the most common ring size systems in the United States (US), United Kingdom (UK), and Europe (EU), and show you how to measure your size accurately and easily.
Why Is Knowing Your Ring Size Important?
Wearing a ring that doesn’t fit properly can be uncomfortable and even ruin the experience of owning such a special piece of jewelry. Additionally, incorrect sizing can complicate the purchase process, especially for custom-made or handmade rings.
Key Ring Sizing Systems
1. US Ring Size System
The US ring sizing system uses numbers (e.g., 6, 7, 8) with increments of 0.4 mm in the inner diameter of the ring. For example:
- US 6: 16.5 mm diameter
- US 7: 17.3 mm diameter
- US 8: 18.1 mm diameter
This system is widely used across North America and is commonly found in online stores.
2. UK Ring Size System
The UK system uses letters (A, B, C, etc.) to indicate sizes. Each letter represents an increase of 1.25 mm in the ring's inner circumference. For instance:
- UK K: 50 mm circumference (16 mm diameter)
- UK M: 52 mm circumference (16.5 mm diameter)
- UK O: 55 mm circumference (17.5 mm diameter)
3. EU Ring Size System
The European system is based on the ring's inner circumference in millimeters. This makes it straightforward:
- EU 52: 52 mm circumference
- EU 56: 56 mm circumference
- EU 60: 60 mm circumference
This system is the standard in countries like Spain, France, Italy, and Germany.

If you can’t visit a jeweler, here are two easy methods to determine your ring size at home:
Method 1: Use a Ring You Already Own
- Take a ring that fits well on the intended finger.
- Measure its inner diameter using a ruler or caliper.
- Refer to a ring size conversion chart to find your size in US, UK, or EU systems.
| Inner Diameter (mm) | US | UK | EU |
|---|---|---|---|
| 16.5 | 6 | K | 52 |
| 17.3 | 7 | N | 54 |
| 18.1 | 8 | P | 57 |
Method 2: Use a String or Paper Strip
- Wrap a piece of string or a strip of paper around the base of your finger.
- Mark where the string or paper overlaps.
- Measure the length in millimeters (this is your finger’s circumference).
- Use the conversion chart below to find your size:
| Finger Circumference (mm) | US | UK | EU |
|---|
| 50 | 5 | J | 50 |
| 52 | 6 | L | 52 |
| 54 | 7 | N | 54 |
Tips for Accurate Ring Sizing
- Measure at the right time of day: Fingers can swell or shrink depending on temperature or fluid intake. The best time to measure is in the afternoon or evening.
- Don’t make it too tight: If using string or paper, ensure it’s snug but not overly tight.
- Consider ring width: Wider rings may require a slightly larger size for comfort.
