How to Measure Your Ring Size
Two easy methods you can do at home
01
String or Paper Strip
What You'll Need
A piece of string or a thin strip of paper, a ruler, and a pen- Wrap a strip of paper or string around the base of your finger
- Keep it snug but comfortable — it should slide over your knuckle
- Mark where it overlaps, then measure the length in mm — that's your circumference
- Match it to the chart above
02
Use an Existing Ring
What You'll Need
A well-fitting ring and a ruler (or calipers for best accuracy)- Place a well-fitting ring flat on a ruler or calipers
- Measure the inside diameter (inner wall to inner wall) in mm or inches
- Find the closest match in the "Inner Diameter" column above
- Between two sizes? Choose the larger one
Helpful Tips
- Best time to measure: Measure in the afternoon or evening when your fingers are at their most stable size. Fingers tend to be slimmer in the morning and larger after exercise.
- Temperature matters: Cold weather can cause fingers to shrink slightly, while warm weather causes slight swelling. Always measure when your hands are warm and relaxed.
- Measure more than once: We recommend measuring 2–3 times at different times of day and going with the most consistent result.
- Left vs. right hand: The same finger on your left and right hand may differ in size. Always measure the exact finger you plan to wear the ring on.
- Wide bands: Wide band styles tend to fit more snugly. We recommend selecting the larger of your two closest sizes.
- Larger knuckles: If your knuckle is noticeably larger than the base of your finger, choose a size that slides comfortably over the knuckle.
- Between two sizes? When in doubt, go with the larger size — a slightly loose ring is more comfortable than one that's too tight.
✦ About the engraving inside your ring
Our rings are sized in US standards. You may notice a different number engraved inside the ring — this simply reflects an alternative sizing notation based on inner diameter, and does not affect your fit in any way.
