RING SIZE GUIDE
Do you already have a ring that fits the finger you're shopping for?
- Use a ruler to measure the inside diameter of a ring that fits the desired finger (in mm).
- Compare the measurement with the following table .
- Round up if you are between sizes.
| Inner diameter (mm) | Ring Size (US) |
|---|---|
| 13.2 | 2 |
| 14.1 | 3 |
| 14.9 | 4 |
| 15.7 | 5 |
| 16.5 | 6 |
| 17.3 | 7 |
| 18.1 | 8 |
| 19.0 | 9 |
| 19.8 | 10 |
| 20.6 | 11 |
| 21.4 | 12 |
| 22.2 | 13 |
| 23.1 | 14 |
| 24.0 | 15 |
| 24.8 | 16 |
- Cut a thin strip of paper 10–12 cm long.
- Wrap the strip of paper firmly around the desired finger.
- Using a pen or pencil, mark where the paper overlaps itself.
- Place the strip of paper on a flat surface and, using a ruler, measure the distance in millimeters from the end of the strip to the mark you made. This will give you the circumference of your finger.
- Using the table below, convert your measurement to standard US sizes.
- If you are between two sizes, it is better to round up rather than down.
| Circumference (mm) | Ring Size (US) |
|---|---|
| 41.5 | 2 |
| 44.1 | 3 |
| 46.9 | 4 |
| 49.3 | 5 |
| 51.9 | 6 |
| 54.5 | 7 |
| 57.2 | 8 |
| 59.3 | 9 |
| 62.3 | 10 |
| 65.0 | 11 |
| 67.5 | 12 |
| 70.1 | 13 |
| 72.7 | 14 |
| 75.4 | 15 |
| 78.0 | 16 |

- Print our ring sizer in PDF format (choose A4 or Letter) at 100% scale . Make sure the “fit to page” option is disabled in the print settings.
- Measure the gray section: it should measure 3.5 inches (8.89 cm) from end to end.
- Cut out the measuring tool (the top section that looks like a ruler) and wrap the paper tightly around the finger you want to measure. The number that most closely aligns with the “Read size here” line will be your size.
- Alternatively, if you have a ring that fits you well (or you know it fits the person you're giving it to), place it over each size circle until you find the corresponding size. The correct circle should fit perfectly inside the ring.
- If you are between two sizes, it is better to round up rather than down.
