Ring sizing is one of the most common reasons orders get returned or resized. Take five minutes here and you'll get it right the first time.
The easy way
Pick whichever feels easiest — they all read against the same chart below.
- Measure on screen — Calibrate with a credit card, then match an existing ring against an on-screen circle. Works on phone, tablet or laptop. No printer needed.
- Order a free home sizer — We post a physical sizer to anywhere in the GCC and the Levant at no charge.
- Print a sizer at home — Our 1:1-scale sizer on A4. Cut, wrap, read. Two pages of charts included.
Or measure it yourself
1. Use an existing ring
Take a ring that fits the right finger comfortably (not too tight, not slipping off). Measure the inner diameter in millimetres with a ruler, then match against the chart below.
2. Wrap a strip of paper
Cut a thin strip of paper about 100 mm long. Wrap it snugly around the base of the finger, mark where it overlaps, then lay it flat and measure the length in millimetres. That's your finger's circumference — match against the chart.
3. Ask a jeweller
Any jewellery shop will size your finger for free in under a minute. Bring the result back here.
Size chart
Diameter is the authoritative measurement; circumference is just π × diameter. EU numbers follow ISO 8653:2016 (size = inside circumference in mm). UK letters follow the Wheatsheaf / British Standard gauge — half-letter glyphs up to W½, then Y, Z, Z+1 … Z+6 past Z. JP (gō / 号) is the Japanese industry scale; no equivalent below US 2 or above US 14.5.
| US size | UK size | EU size | JP size | Inside diameter (mm) | Circumference (mm) |
|---|---|---|---|---|---|
| 1 | B½ | 39 | — | 12.44 | 39.09 |
| 1.5 | C½ | 40 | — | 12.85 | 40.37 |
| 2 | D½ | 42 | 1 | 13.26 | 41.64 |
| 2.5 | E½ | 43 | 2 | 13.66 | 42.92 |

Tips
- Measure at the end of the day, when fingers tend to be slightly larger.
- Avoid measuring when cold — fingers shrink.
- Wider bands (over 6 mm) typically fit a half-size tighter than narrow bands.
- If you're between sizes, go up — a slightly loose ring is easier to resize down than the other way around.
