Ring Size Guide
Find your Northlord ring size in three simple steps: measure the circumference of your finger in millimetres, find your measurement in the first column, then choose the corresponding US / Northlord size on the product page. If you already know your EU or UK size, use the same chart to convert it.
1. Measure your finger
Use a thin strip of paper (or non-stretch string) and a millimetre ruler. Your measurement is your finger circumference ā the distance around the finger where the ring will sit.

- Wrap the strip snugly around the base of the finger you will wear the ring on. Do not pull it too tight.
- Mark the exact place where the paper overlaps.
- Lay the paper flat and measure from the starting edge to the mark in millimetres (mm).
- Repeat the measurement two or three times. Check that the strip can also slide comfortably over your knuckle.
- Find your measurement in the chart and select the corresponding Northlord / US ring size from the options available for your chosen ring.
2. Find your Northlord ring size
The first column gives the approximate finger / ring inner circumference in mm. Northlord uses the US / Canada sizing system for ring options. EU sizes are rounded circumference equivalents; UK sizes are approximate letter equivalents.
Example: If your finger measures around 60 mm, choose approximately US / Northlord 9 (EU 60; UK S).
| Circumference (mm) | Northlord / US | EU (approx.) | UK (approx.) | Diameter (mm) |
|---|---|---|---|---|

| 51.9 | 6 | 52 | L½ | 16.5 |
| 53.1 | 6.5 | 53 | M½ | 16.9 |
| 54.4 | 7 | 54 | N½ | 17.3 |
| 55.7 | 7.5 | 56 | P | 17.7 |
| 57.0 | 8 | 57 | Q | 18.1 |
| 58.3 | 8.5 | 58 | R | 18.5 |
| 59.5 | 9 | 60 | S | 18.9 |
| 60.8 | 9.5 | 61 | T | 19.4 |
| 62.1 | 10 | 62 | U | 19.8 |
| 63.4 | 10.5 | 63 | V | 20.2 |
| 64.6 | 11 | 65 | W | 20.6 |
| 65.9 | 11.5 | 66 | W¾ | 21.0 |
| 67.2 | 12 | 67 | Y | 21.4 |
| 68.5 | 12.5 | 69 | Z | 21.8 |
| 69.7 | 13 | 70 | Z+1 | 22.2 |
| 71.0 | 13.5 | 71 | Z+2 | 22.6 |
| 72.3 | 14 | 72 | Z+3 | 23.0 |
| 73.6 | 14.5 | 74 | Z+4 | 23.4 |
| 74.8 | 15 | 75 | Z+5 | 23.8 |
The figures are reference conversions, not exact equivalences in every country's sizing system. Your measured circumference and the selected product's available US sizes are the best starting points. Not every Northlord ring is offered in every listed size.
3. Measure a ring you already own (optional)
- Choose a ring that fits the same finger comfortably.
- Measure straight across the inside of the ring at its widest point, without including the metal.
- Match this inside diameter in millimetres to the final column of the chart.
Tips for a comfortable fit
- Measure in the evening, when your hands are at a comfortable temperature. Avoid measuring fingers when very cold.
- If your result is between available sizes, the larger size is usually the more comfortable choice.
- Wide bands often feel tighter than slim rings. Consider a slightly larger size when appropriate.
- Remember that fingers on your left and right hands may differ in size.
- For an especially wide, heavy or made-to-order ring, we recommend confirming your size with a local jeweller before ordering.
