Find your ring size

  1. Print at 100% / Actual Size — turn off "fit to page" or scaling.
  2. Check the printed ruler measures exactly 80 mm.

Method A — Measure a ring

Lay a ring you own over the circles. The matching circle is your size.

Method B — Finger strip

Cut out the strip, wrap it around your finger, thread the end through the slit, and read your size.

1. Calibrate your screen — pick a reference object, hold it against the outline, and drag until the widths match exactly. On a phone, a coin is easiest — a card is often wider than the screen.
Bank card — hold vertically
2. Match a ring you own — drag until the circle fits just inside one of your rings.

Such a beautiful ring!

Such a beautiful ring! It's not as bright colored as shown online, but it's okay because it is still just so beautiful. I love it so much. The diamond is also a very nery nice size, bigger than I was expecting (in a good way).

We're so happy to hear you love your ring. Thanks for sharing your kind words, and we're glad the size exceeded your expectations. Enjoy wearing it!
