Finger Sizing and Ring Size Chart

Men's and women's ring sizes are the same, unlike clothes and shoes that are a specific measurement for men and women. Most individuals think that there is a difference in rings and wedding band sizes too. Rings are sized by a constant measurement of the inner diameter of the band. A men's size 9 ring measures the same size as a women's size 9.

Important note:

Bands will vary on the width, which can be deceiving to the inner diameter. The wider the band, the larger size may be required. The inner diameter might be the same, but a wider band will feel tighter due to the amount of metal in contact with your finger as it slides over your knuckle. If you wear a size 7 in a thin 1.5mm wide band, a size 7 in a wider 8mm band may feel tight even knowing both are a size 7. We recommend a half or full size larger if you transfer from a thin band to a wider band.

We have an easy exchange process if you order the wrong inner diameter. If you do not know your ring size, we suggest you get one of our quick finger sizing tools here.
