How to Measure Ring Size at Home

Unsure about your ring size? These three simple at-home methods will help you find your perfect fit.

1. Make Your Own Ring Sizer

Tools to measure ring size at home – ruler, pen, and notepad for sizing

What you'll need:   

Printer & paper    

String, yarn, floss, or a thin strip of paper    

Pen or marker    

Ruler  

Steps:   

1. Cut a piece of string, yarn, floss, or a thin strip of paper to at least three inches long.   

2. Wrap one end of the string around the base of the intended finger.

3. Using a pen or marker, mark where the end of the string overlaps with the rest.

4. Lay the string flat and use a ruler to measure the length between the end and your mark in millimeters.

5. Use the Ring Size Conversion Chart to match the millimeter length to the corresponding ring size.

2. Print A Ring Sizer

What you'll need:   

Printer & paper   

Scissors   

Steps:

1. Print the Printable Ring Sizer & Conversion Chart. Set page scaling to "100" in your print settings and use 8.5 x 11-inch standard paper.

2. Cut out the ring sizer and the slot as instructed. 

3. Wrap the paper ring sizer snuggly around the base of the intended finger so that the numbers are visible and insert the pointed end through the slit you made in the sizer.

4. Note the number that lines up with the slit; this is your ring size! Remember that quarter sizes are also available if your sizer indicates that you are between whole and half sizes.
