How to Measure Your Ring Size

Method 1: Use a Ring You Already Own

1. Measure the Inner Diameter:

• Place the ring on a ruler and measure the inner diameter in millimeters (mm) or inches.
• Match the measurement to the chart above.

2. Measure the Inner Circumference:

• Wrap a string around the ring’s inner edge, mark the length, and measure it.
• Compare to the "Inner Circumference" column.

 

Method 2: Use a String or Paper Strip

1. Wrap Around Your Finger:

• Use a non-stretchy string or paper strip and wrap it snugly around the base of your finger.
• Mark where the ends overlap.

2. Measure the Length:

• Use a ruler to measure the marked length in mm or inches.
• Match the measurement to the chart.

Method 3: Visit a Jeweler

Tips for Accuracy

• If you are in between sizes, always size up for maximum comfort
• Measure at the end of the day (fingers are slightly larger).
• Avoid cold hands (cold temperatures shrink fingers).
• Wider bands fit tighter—consider sizing up for bands over 6mm (0.24 inches) wide.
• Check knuckle size: Choose a size that slides comfortably over your knuckle.
