How to Measure Your Ring Size

Find your correct ring size at home using a strip of paper and a ruler.

  1. Wrap a paper strip

    Cut a thin strip of paper or string and wrap it snugly around the base of the finger you want to size. Wrap below the knuckle but make sure it can still slide over the knuckle.

  2. Mark the overlap

    Use a pen to mark the exact point where the strip meets itself, forming a full circle around your finger.

  3. Measure the length

    Lay the strip flat and measure from the start to your mark in millimeters. This is your finger's circumference.

  4. Match to a size chart

    Compare your millimeter measurement to a ring size chart (for example, ~57.8mm is US size 8.5). Measure at the end of the day when fingers are warm, and check 2-3 times for accuracy.
