Wrap paper or tape around your finger
Cut a thin strip of paper or string. Wrap it snugly around the base of your ring finger on your dominant hand, just below the knuckle.
Mark where the strip overlaps
Use a fine pen or marker to draw a clear line exactly where the paper meets itself. This captures your finger circumference.
Measure against a ruler in mm
Lay the paper strip flat against a ruler and measure the distance between marks in millimetres. 59.3mm corresponds to US Size 9.
