Find Your Perfect Ring Size
Step 1: Measure Your Finger
Use a ring that fits well: measure its inner diameter in mm.
Or wrap a string/paper around your finger, mark the overlap, and measure the length in mm.
Step 2: Check the Size Chart
Compare your measurement with the size chart.
Tips:
If you’re between sizes, choose the larger one.
Measure your knuckle if it’s wider than your finger base.
Measure in the evening when your fingers are largest.
For gifts, borrow a ring and measure its diameter.
