- Take a piece of non-stretchy string, ribbon, thread, or a thin strip of paper and wrap it snugly around the base of your finger. With a pen, carefully mark the point on the string or paper where it overlaps, forming a complete circle.
- Lay it flat and use a ruler to measure the length in millimeters. This is the circumference of your finger. Use the chart below to find the corresponding ring size (Inside Circumference).
- Make sure your finger is at a normal body temperature – fingers can shrink or swell 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. It is always a good idea to measure your finger size 3 to 4 times to eliminate an erroneous reading.
