How to Measure at Home?

  • Method 1: Measure an Existing Ring (Most Accurate)

    1. Take a ring that currently fits your desired finger perfectly.
    2. Use a ruler to measure the inner diameter at the widest point of the circle (in millimeters, excluding the metal border).
    3. Compare the measurement with the "Inner Diameter" columns above to find your Aurae size.

  • Method 2: Measure Your Finger

    1. Cut a thin strip of paper (about 1cm wide) and wrap it snugly around the base of your finger.
    2. Mark the exact spot where the paper overlaps with a pen.
    3. Measure the length from the start to the mark with a ruler (in mm) and compare it to the "Inner Circumference" columns above.

  • Measure Paper Length

    Flatten the paper strip and measure the exact length from the start to your mark in mm to find the circumference.

💡 Aurae Size Tips:

Temperature Matters: Fingers tend to swell slightly in warm weather and shrink in the cold. We recommend measuring at the end of the day when your fingers are at their average size.

Wide Bands: Rings with wider bands sit tighter on the finger. If you are eyeing a statement thick-band piece, consider ordering one size up.

Between Sizes?: If you fall between two sizes, Aurae always recommends choosing the larger size for the most comfortable wear.
