How can I measure my ring size at home?

VRAI offers ring sizers, which makes finding your ring size at home effortless. Should you need to measure your ring size right away without a ring sizer, however, you can do the following:

1. Use floss or a piece of string to wrap around the base of your finger.
2. Mark where the string overlaps with a pen.
3. Lay the string down on a ruler and take down the length in millimeters.

4. Look at the ring size chart to see which size corresponds to your measurement.

   How can I get a ring sizer?

VRAI’s ring sizers can be ordered and shipped to your home. Simply follow the link, click “Add to bag,” and the sizer will be shipped anywhere in the US or UK free of charge.

How do I use a ring sizer?

1. Secure the end of the sizer through the buckle to form a ring shape.
2. Slip your desired finger through the loop.
3. Pull the end through until the sizer fits snug but is not overly tight.
4. When it fits correctly, look at the little black arrow and note your ring size.

No need to get out the ruler or string. You now know your ring size. Keep the sizer to measure correctly for every time you shop for a new ring.

How can I find my ring size in inches?

Most ring sizes are measured in millimeters, but if you’d like to know your ring size in inches, note that there are 25.4 millimeters per inch.

1. Measure your finger with string (or use your ring sizer)
2. Note the circumference in millimeters.
3. Divide by 25.4

For example, a ring that is size 7 is 54 millimeters in circumference, so 2 ⅛ inches.

How can I find my ring size in centimeters?

The same principle applies when converting your ring measurement to centimeters. There are 10 millimeters to a centimeter. Divide the number of millimeters by ten.

A size 10 ring is 61.9 millimeters, so 6.19 centimeters. Explore our ring size conversion chart to learn more.
