Sizing Guide

Rings are created true to standard US sizing. For the best fit we suggest having your finger(s) sized. We offer a physical ring sizer as well! Alternatively, you may follow the steps below to find your best fit:

  1. Wrap a string around your finger where you'd like your ring to be or place the string across the inner diameter of a ring that fits you from end to end.
  2. Make sure that the string is pulled snug for the best accuracy
  3. Mark the spot where the string meets and measure with a ruler in millimeters (circumference) or measure the string's distance across the center of the ring (inner diameter)
  4. Use the circumference or inner diameter column in the chart here to find your size

    Great purchase

    I’m really glad I bought this ring sizer. I was honestly guessing my ring size before and kept ordering rings that didn’t fit right, so this saved me a lot of time and returns. It was super easy to use, and I like that I could try different sizes on multiple fingers to see what felt comfortable instead of just tight. The numbers were clear to read and it actually feels pretty durable for the price. Now I feel way more confident ordering rings online. Definitely worth getting if you’re unsure about your size.

    Great!

    Effective and easy to use. I will say that the half sizes are a bit confusing
