Don't know your ring size? Use this tool to measure your finger. When you purchase the ring sizer, you will get an email with a $3 Knockout gift card.

The plastic finger gauge measures U.S. sizes 1–17 in half-size increments; the increments are clearly marked.

For lucite sizing, we suggest a loose fit with the sizer (easy to take on and off), as the lucite sizing runs a bit small.

If you're sizing for a metal ring, you want the ring sizer to resist a bit at the knuckle. The way you like to wear your ring might be looser or tighter, so get what feels right, and we can swap out sizes if need be.
