Method 1 — Measure Your Finger at Home (2 Minutes)
This is the fastest and most popular method.
What You Need
•A thin strip of paper or string
•A ruler (millimeters preferred)
•A pen
Step-by-Step
1.Wrap the paper or string around the base of your finger.
2.Make sure it feels snug but comfortable.
3.Mark where the ends meet.
4.Measure the length in millimeters.
5.Use our ring size chart to find your size.
💡 Pro Tip: Measure 2–3 times to ensure accuracy.
Method 2 — Use a Ring You Already Own
If you have a ring that fits perfectly:
1.Place the ring on a ruler.
2.Measure the inside diameter (not the outer edge).
3.Compare it with our sizing chart.
✔ Always measure a ring worn on the same finger.
Best Time to Measure Your Finger
For the most accurate result:
•Measure in the evening (fingers are at natural size)
•Keep hands at normal room temperature
•Avoid measuring right after exercise or when cold
Finger size naturally changes during the day — this is completely normal.
How a Perfect Ring Should Feel
Your ring should:
✔ Slide on smoothly
✔ Sit comfortably without squeezing
✔ Require slight resistance when removing
✔ Stay secure during daily movement
If you are between sizes, we recommend choosing the larger size for comfort.
Helpful Sizing Tips (Most Customers Miss These)
•Wider bands feel tighter → consider ½ size up
•Your dominant hand is slightly larger
•Knuckles may affect sizing — measure both base and knuckle
These small details make a big difference in everyday comfort.
