Tips for Measuring a Man's Ring Size: Don't measure cold fingers, as this is when fingers are the smallest.
The best time to measure a finger is at the end of the day when the finger is the largest.
Take at least two measurements for accuracy.
Size Yourself: Wrap a thin strip of paper or piece of string around the base of the finger you want to measure.
With a pen, mark the point on the paper or string where it overlaps, forming a circle on the finger.
Measure the length of the paper or string using a flat ruler, from the starting point to the pen mark.
