How to Measure Your Ring Size
Women simply adore rings—whether for birthdays, anniversaries, or just because. But engagement rings, embellished with precious stones, hold a special fascination.
For the most accurate and professional ring sizing, visit a jeweler.
Since that’s often not possible, Zoy-i Jewelry has prepared a few ideas for how to measure ring size—whether for yourself or your dearest person.
How to Measure Your Ring Size
If you're buying a ring for yourself and want to measure your finger size at home, you can use a non-stretchable string. Wrap it around the desired finger, but not too tightly. Make sure to measure the thickest part (the knuckle). Then mark where the string overlaps, measure its length with a ruler, and compare it to the size chart below.
The best way to get your exact ring size?
-
Visit a jewelry store and try on rings until you find your perfect fit.
-
Ask the staff to measure the ring's diameter for you.
-
Simply check our size chart to find your matching size!
Helpful Tips for Measuring Your Finger:
-
Hand Differences: Fingers on your left hand aren't the same size as those on your right (your writing hand is usually half a size larger).
-
Daily Changes: Fingers fluctuate throughout the day. They tend to be slightly wider in the evening and during summer compared to mornings or winter months (we recommend measuring when hands are warm).
-
Ring Width: For wider bands, choose a slightly larger size than you would for narrower rings.
-
Average Sizes: The average women's ring size is 53.
Note: For engagement rings or precise sizing, professional measurement at a jeweler is always best.
