Finding your ring size is easy! Here are two methods for measuring your ring size in mm or Inches.
Method A: How to Measure Ring Finger Size
Step 1 – Get a non-stretchy string or paper about 6″(152mm) long and 1/4″(6.5mm) wide.
Step 2 – Wrap around the base of your finger. It has to fit snug, but not too tight.
Step 3 – Mark the point on the string/paper where it overlaps forming a circle.
Step 4 – Measure the length of the string/paper from the starting point to the mark.
Step 5 – To determine your ring size in all countries open our Ring Size Conversion Chart for mm or Inches.

Ring finger measuring tips
If you are between sizes, order a larger size. Make sure your finger is at a normal body temperature — fingers can shrink or expand when cold or hot. If your knuckle is much larger than your finger’s base, take two separate measurements and choose a size in between. You want a ring to fit over your knuckle, but not be too loose or it will shift around.

We recommend you try your ring size on at your jeweler’s: the sales staff at the House of DIV will be happy to help you choose your ring in the best possible size for you.

Also, adjustment to size can be done for certain rings, according to the model, the material or the type of setting: your jeweler can tell you whether the ring you want can be adjusted to size or not.
