How to Determine your Ring Size

Knowing your ring size will make shopping for rings easier.

Buying a ring for yourself or someone you love is an exciting time, and often a major purchase that should be carefully considered. One of the first things to determine is the size of the ring. In the U.S. and Canada, rings are sized by a numbering system that corresponds to a circumference. Jewelry stores have sizing measures available for customers, but there is an easy way to measure your ring size at home as well.

Instructions

Things You'll Need

• Ruler
• String
• Marker
• Size chart

1. Find a ring size chart online and print it out.

2. Wrap a piece of string around your ring finger halfway between the knuckle and the first joint. Wrap the string loosely to not stretch it. Make sure the loop of the string can still slip over your finger joint.

3. Mark the string where the loop ends meet on your finger.

4. Lay the string flat and measure the segment between marks with a ruler.

5. Look up the length on the size chart to determine your ring size.

Tips & Warnings

• Measure your finger toward the end of the day, when fingers tend to be most swollen.

• Perform several measurements and take an average to get a best size estimate.

• Some ring size charts come with a ring sizing tape measure that can be cut out and used. Be wary of these, as slight differences in printer settings can throw off their size and thus the results.
