📏 Ring Size Guide & Knuckle-Fit Tips

How to Measure Your Ring Size

Finger base (standard fit): Wrap a thin strip of paper or a flexible tape measure around the base of your finger. Mark where it overlaps, measure the length in millimeters, then use the table below to find your US size.

Knuckle fit: If your knuckle is wider than your finger base, measure both and choose the size that slides comfortably over the knuckle. The ring will have a little extra room at the base — this is normal for knuckle sizing and helps the spinner chain move freely.

Best time to measure: Fingers swell slightly in warmth and at the end of the day, so measure in the evening or after light activity for the most accurate fit.

This product covers US sizes 10–13. Need sizes 6–9? See our Cool Rotatable Rings size 6 to 9.

⚠️ A Note on Resizing Spinner Rings

Spinner (rotatable) rings have a two-part construction — an outer spinning band and an inner base ring — which makes resizing more involved than a standard ring. Based on feedback from buyers and jewelers, resizing a spinner ring can affect how smoothly the outer chain rotates, and in some cases the spinning action may be altered or need readjustment after the work is done. We strongly recommend ordering your correct size from the start. If you are between sizes or have a prominent knuckle, sizing up is generally the safer choice for comfort and spinner function.
