Using a string or paper:

• Cut a strip of paper or ribbon and wrap it around your finger. Use a pen to mark where the two ends meet.
• Using a ruler, measure the length ribbon or paper in millimeters. If you are between sizes, size up.
• If your knuckles are larger than the base of the finger, measure both the knuckle and finger and select a size in between the two. 

Using a ring:

• Using an existing ring, use a ruler to measure the inside diameter of this ring. Just use a ruler and measure straight across the inside of the ring from edge to edge.

Thinks to Consider it:

• Your fingers are usually at their largest at the end of the day, so we suggest measuring them in the evening.
• Cold weather can shrink your fingers, so ensure that your hands are warm.
• Our dominant hand tends to be slightly bigger
