Find Your Ring Size
All Shiftd rings are sized in US whole and half sizes (2–14). Use one of the methods below to find your perfect fit before ordering.
Method 1: Measure an Existing Ring
Place a ring you already own and love the fit of on a ruler. Measure the inside diameter in millimeters, then match it to the chart below.
Method 2: Measure Your Finger at Home
- Cut a thin strip of paper (about 6mm / ¼" wide).
- Wrap it snugly around the base of the finger you plan to wear the ring on.
- Mark where the paper overlaps, then lay it flat against a ruler.
- Note the measurement in millimeters and find your size in the chart below.
Tip: Fingers are slightly larger in the evening and in warm weather. Measure at the end of the day for the most accurate fit.

Between Sizes?
If you fall between two sizes, we recommend sizing up — especially for wider band styles like the Cleo Hammered Band Ring.
