Ring sizing
Find your size in 2 minutes.
Three foolproof ways to measure at home. If you're between sizes, go up — easier to wear, easier to resize down.
Method 1 — String or floss
- Wrap a piece of string around the base of your finger.
- Mark where it overlaps with a pen.
- Lay it flat against a ruler — measure the length in millimeters.
- Match to the circumference column below.
Method 2 — Existing ring
Place a ring you already wear on the finger you want to size. Measure its inner diameter in millimeters, then match the diameter column below.
Method 3 — Free sizer
Add a “Free Ring Sizer” to your cart and check out for free. Arrives in 3–5 days. Once you know your size, place your order — we'll refund the sizer or include credit in your next purchase.

Tips
- Measure at the end of the day — fingers are slightly larger.
- Avoid measuring when cold; fingers shrink.
- Wider bands (4mm+) fit tighter — go up half a size.
