Size Chart

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.

Open the printable sizer (PDF)
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.

IN LOVE

My boyfriend and I bought these for our 1 year anniversary. We were BEYOND blown away at the quality. These rings are AMAZING! We are so in love and they’re so nice and lowkey pretty comfy! Usually with most rings I can feel them on my hand and I don’t like it, but with this one I forget it’s there! In love 😍🖤

What a wonderful way to celebrate your anniversary, Shaylee! We’re so glad you and your boyfriend love the rings. Wishing you both many more happy years together! ❤️

Ring sizes seem larger then they should be

Rings look as advertised but sizing is wrong and I have to pay 55$ per ring to resize. I ordered the right sizes, confirmed our ring sizes and have other rings in those sizes yet the rings from aquamarise don't fit.
