There are several ways to measure your ring size. These include:

1. Get a piece of string or a paper strap. Wrap it around the finger you want to put a ring. Make sure the string sits firmly on the finger. It should not dig into it.

          

2. Mark the point where the paper or string overlaps after forming a full circle using a pen

        

3. Use a ruler to measure the length of the string or paper in millimeters, from its start to where the mark is. Find the corresponding ring size using a ring size chart

    

 

Measure The Size Of A Ring You Already Have

Do you have a ring that fits you perfectly, but you don’t know its size? You can use it to know your ring size measurement. Take the ring and measure it from edge to edge across its inner part using a ruler. Take the diameter in millimeters and use a measurement conversion chart to know your size.
