Ring Size Guide | Free 90-Day Size Exchange

Get the size right. If you don't, we'll swap it.

These metals don't resize like gold. That's the point — they're too hard. So we don't stretch them. We exchange them, free, for 90 days.

How to measure

  1. Measure at the end of the day, when your finger is largest.
  2. Use a plastic ring sizer or a ring you already wear on that finger. Paper strips stretch and run small.
  3. The ring should pass the knuckle with a little resistance, then sit snug.
  4. Between sizes? Size up. A ring you can get off is easier than one you can't.

Order a physical sizer

Paper strips run small. We ship a plastic zip-tie sizer for $10. Measure at home, then order the ring. Get the sizer.

What we stock

  • Tungsten and F1 carbon: whole and half sizes, 8 through 12.5
  • Tantalum, black zirconium, Dominator, Crusader: whole sizes 8 through 12

If your size isn't listed, email info@alpharings.com before you order. Don't guess.

If it doesn't fit

90 days from delivery, free size exchange. Surprise gift? The window can start on the wedding date (send us a photo or the date). Email info@alpharings.com with your order number.

We cannot traditionally resize these rings. An exchange is the right move, not a local jeweler.
