Finding the perfect ring is exciting — but ordering the wrong size can be frustrating. The good news? You don't need to visit a jeweller to figure out your ring size. With a few simple tools you already have at home, you can measure accurately and shop with confidence.
Method 1: The String or Paper Strip Method
Wrap a thin strip of paper or piece of string around the base of your finger. Mark where it overlaps, then measure the length in millimetres against a ruler. Use the table below to find your size:
- 47mm = Size 13
- 48mm = Size 14
- 49mm = Size 15
- 52mm = Size 16
- 55mm = Size 17
- 57mm = Size 18
- 60mm = Size 19
- 63mm = Size 20
Method 2: Measure an Existing Ring
If you already own a ring that fits well, place it on a ruler and measure the inner diameter in millimetres. Match it to the sizes above.
Tips for the Best Fit
- Measure at the end of the day when fingers are slightly larger.
- If you're between sizes, go up — a slightly loose ring is easier to wear than a tight one.
- Fingers can change size with temperature, so measure on a day that's not too hot or cold.
