In order to print the Men's ring sizer , be sure that your printer is set to 100%. Make sure that you have not reduced the print size in your printer 'page setup' area. You can verify that the sizer printed correctly by measuring it with a ruler; it should measure from A to B: 3 1/2 inches long.

Once you have printed the sizer, follow these directions to find your men's ring size: Up to size 15

Cut out the men's ring sizer
Cut a slit for Slot "A"
With the numbers facing out, wrap the sizer around the finger where the ring will be worn.
Pull the pointed end Tab "B" through Slot "A" until the sizer is snug, making sure to allow size for the knuckle.
The number aligned with Slot "B" is your men's ring size.
If the measure lands between two numbers your size is a half size Ex: Between 11 and 12 ring size: 11.5. If half sizes are not available, order the next largest size.

Ask your partner's mother or one of the friends if they know the finger size.
