How to Measure Ring Size?

There are several ways to measure for your ring size, including buying a ring sizer. But let's keep things simple shall we? 

Option 1 

You can measure your ring size using either string or, perhaps a more common item in your home, dental floss. Take the string or dental floss and wrap it around the base of your finger, marking where the string or floss first overlaps with a pen. Then, line that up with a ruler and take down its length in millimeters.

With standard ring sizes, every half-size matches up to a 0.4 millimeter increment, starting with size 3 equaling 14 mm, size 3.5 equal to 14.4 mm, size 4 equal to 14.8 mm, and so on. Common ring sizes for women are 6 (16.5 mm), 6.5 (16.9 mm), and 7 (17.3 mm).

22.2 mm. 13 -
22.6 mm. 13½ -

Option 2

If you have a ring that already fits your finger well, you can use a ruler to measure the inside diameter of this ring. Just take your ruler and measure straight across the inside of the ring from edge to edge. Take the diameter measurement in millimeters, and then use our measurement-conversion chart to find your ring size.

Hope this helps!
