Ring sizing chart
How to measure your ring size (approximately)
1. Wrap a strip of paper around your finger between the base and knuckle. You should do this a few times in one day to get an accurate measurement as your finger can change size.
2. Mark the paper where it overlaps to form a complete circle and measure the distance with a measuring tape or ruler.
3. Compare your measurement with the chart below to determine your ring size.
