Ring Sizing Guide
Getting your ring size right at home is simple. Choose the method that works best for you — we recommend confirming with two methods before placing a made-to-order or finish-to-size order.
Method 1 — Use our printable ring sizer
Our printable guide includes a cut-out size strip sizer and a ring-matching circle chart — the most accurate at-home options available.
- Print at 100% scale on US Letter paper (8.5" × 11"). Do not scale to fit.
- Verify accuracy using the 2-inch reference line printed on the sheet before cutting.
- Size strip: Cut out the strip, make a small slit at line "A," wrap it around your finger numbers-out, insert the pointed end through the slit, tighten until snug, and read your size at the arrow.
- Circle chart: Place an existing ring over the circles and match the inside edge to the circle that lines up perfectly.
- If between sizes, size up.

Tip: Measure in the evening — fingers are slightly larger later in the day. Cold fingers run small, so always measure at room temperature.
Method 2 — Measure an existing ring
Have a ring that already fits the finger you're shopping for? Lay it flat on a ruler and measure the inside diameter in millimeters, then match to the chart below. You can also use the circle chart in our printable guide — just lay your ring over the printed circles.
Tip: Measure the inside of the band, not the outer edge. Wider bands (over 6mm) fit more snugly — consider sizing up half a size.
Method 3 — Visit a local jeweler
Any local jeweler can measure your ring size for free in under a minute using professional ring sizers. This is especially helpful if your knuckle is larger than the base of your finger, or if you're ordering a wider band. Ask specifically for your US ring size.

A few helpful notes
- Dominant hand runs larger. Make sure you're measuring the correct hand for the ring you're ordering.
- Knuckle size. If your knuckle is wider than the base of your finger, measure both and choose a size in between.
- Wider bands fit snugger. For bands wider than 6mm, size up half a size for comfort.
- Temperature matters. Always measure at room temperature — cold fingers measure smaller than they really are.
