Interactive Size Guide
Because keeper rings are wide and substantial, we recommend ordering half a size to a full size larger than your standard thin-band measurement.

1How to measure circumference
Wrap a piece of string or a thin strip of paper around the base of the finger you intend to wear the ring on. Mark where the string overlaps, then measure the length flat against a ruler in millimeters.
2How to measure diameter
Take a ring that currently fits the intended finger perfectly. Place it flat on a ruler and measure the inside distance straight across the widest point in millimeters.
Crucial Note on Heavy Rings
Keeper rings are thick, multi-row bands. A wide band displaces more flesh on the finger than a standard wedding band. If your measurement lands exactly on a Size T, you should strongly consider ordering a Size U for comfort.
