Men's Ring Size Guide (String Method)

Fear of getting the size wrong blocks a lot of online ring purchases. That's a shame, because measuring your finger circumference takes two minutes with a simple piece of string. Here's the method, plus a solution that skips measuring altogether.

The string method, in 4 steps

1. Wrap a piece of string or a strip of paper around the base of the finger in question.
2. Mark with a pen where the string meets itself.
3. Unwrap it and measure the length in millimeters with a ruler.
4. This length is your finger circumference. Look it up in the table below.

Size chart

Finger circumference	French size
51 mm	51
54 mm	54
57 mm	57
60 mm	60
63 mm	63

The French size simply equals the finger circumference in millimeters. A 60 mm circumference equals a size 60. The most common men's sizes range from 58 to 64.

Three mistakes to avoid

• Measuring a cold finger. Fingers swell with heat, so measure at the end of the day, at normal temperature instead.
• Pulling the string too tight. The ring must clear the knuckle without forcing, so leave a bit of room.
• Relying on another ring without checking the finger. Each finger has its own size.

The no measuring solution: the adjustable ring

If you're gifting a ring or you're unsure, choose an adjustable model. It opens slightly to fit the finger, with no precise measurement needed. It's the safest solution for a gift. Discover our selection of men's adjustable rings, or the full men's ring collection.

FAQ

How do you measure your ring size without a sizer?

Wrap a piece of string around the base of the finger, mark the point where it meets, then measure the length in millimeters. This number is your French size.

What's the most common men's ring size?

Men most often wear between 58 and 64. For a gift without certainty, an adjustable ring avoids any mistake.

When should you measure your finger?

At the end of the day, at normal temperature. Fingers swell with heat and exertion, so a measurement in the morning or after exercise will skew the result.
