How to Measure Ring Size


Step 1 - Get a non-stretchy string or paper about 152mm (6") long and 6.5mm (1/4") wide.
Step 2 - Wrap around the base of your finger. It has to fit snug, but not too tight.
Step 3 - Mark the point on the string/paper where it overlaps forming a circle.
Step 4 - Measure the length of the string/paper from the starting point to the mark. This is the inside circumference measurement.
Step 5 - Refer to the Ring Size Conversion Chart (below) to determine your ring size in all countries.

Ring finger measuring tips

  • When measuring your finger, your measurements need to be a 100% accurate as even a fraction of a millimeter can make a difference.
  • If you are between sizes, order a larger size.
  • Make sure your finger is at a normal body temperature -- fingers can shrink or expand when cold or hot.
  • If your knuckle is much larger than your finger’s base, take two separate measurements and choose a size in between.
  • You want a ring to fit over your knuckle, but not be too loose or it will shift around.
