Obtaining your finger measurement for rings by using simple household items

• To measure your finger size you’ll need a piece of paper, scissors, a ruler and a pencil

• With this method you’ll learn how to work out ring size by measuring the circumference of your finger


Cut a strip of paper approximately 10mm wide and 100mm long

• On the finger you want to wrap the paper around the WIDEST part of your finger

• Normally the widest part of the finger is the middle knuckle. But for some others the widest part is the end nearest the hand.

• Check that the strip of paper overlaps straight

• Shade out the part of paper that is not around your finger


• Remove the paper, straighten it out along the edge of a ruler
• Measure the part that was around your finger (this is the internal circumference)

the example on the left show a measurement of 60mm making the ring size "S"

• Jot down the measurement on the paper
