How to Measure
1
Choose a ring that fits
Use a ring that already fits the finger where you plan to
wear your new ring.
2
Measure the inside diameter
Measure straight across the widest inside part of the ring
in millimeters. Do not include the metal edges.
3
Find your size
Match your measurement to the closest inside diameter in
the chart above.
A Few Fit Tips
Between two sizes?
Choose the larger size for a more comfortable fit.
Choosing a wider band?
Wider rings can feel slightly tighter, so you may want to
consider sizing up.
Measure more than once.
Finger size can change slightly throughout the day and depending
on temperature.
