Before you begin taking your measurements, pick the finger on which you want to wear your ring. The fingers on your dominant hand tend to be larger than those on your non-dominant hand, so keep that in mind when measuring for your ring size.
Prepping for Measurement
Ensure that your finger is at its normal size before taking a measurement. Cold weather can cause your fingers to shrink a bit, while heat or water retention caused by food, medications, or illness can cause finger swelling.
How Do I Measure My Finger for a Ring?
Our ring size guide includes two ring sizing methods: You can use string or a strip of paper to measure your finger, or you can measure using a ring that you already own.
How do I use String as a Ring Sizer?
- Take a piece of string, ribbon, thread, or a thin strip of paper and wrap it around your finger, close to the knuckle.
- With a pen, carefully mark the spot where the string overlaps with its end and either hold it up to a ruler that has millimeter measurements, or to the graphic below.
- Use the chart to determine your ring size.
