Sizing Chart - Smart Ring

✅ Option 1: Using a Strip of Paper or String

  1. Cut a thin strip of paper or use a piece of non-stretchy string
    About 10mm - 15 mm (¼–½ inch) wide works best.
  2. Wrap it snugly around the base of your finger
    Make sure it’s not too tight or too loose—just enough to mimic a ring’s fit.
  3. Mark the spot where the paper or string overlaps
    Use a pen or marker to mark where it meets.
  4. Lay it flat and measure the length in millimeters (mm)
    Use a ruler to measure from the edge to the mark. This is your finger's circumference.
  5. Match your measurement to the size chart
    Use the mm value to find your ring size in our sizing chart (e.g., 61.5mm = Size 9).


✅ Option 2: Using a Ring You Already Own

  1. Find a ring that fits the same finger you’re buying for

  2. Measure the inner diameter (straight across inside the ring)
    Use a ruler or calliper in millimeters (mm).

       3.Compare to the chart below and compare what diameter you are closest to
Match the diameter to the corresponding size on the chart below
