Choosing the right ring size is always a little difficult, whether for yourself or a partner or friend … here are a few tools to help you get it right first time.
​
HOW TO MEASURE YOUR FINGER FOR A RING SIZE
It is a good idea to measure the finger at the end of the day, when the finger is at its largest, and not to do it when the finger is cold, as this will make it unusually small. Bear in mind that finger sizes change throughout the day.
You can use the above conversion chart and do this can be done very simply. Take a piece of string or a thin strip of paper. Wrap it around the base of the appropriate ring finger. Use a pen to mark the point where it overlaps, forming a complete circle.
Measure the length from the starting end of the string/paper to the pen mark, in millimeters. You will then have the circumference measurement of your finger in millimeters, and can then use the ring size conversion chart to work out your ring size according to several different systems.

TRY OUR PRINTABLE RING SIZER
To print the 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.
​
Cut out the 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 ring size.
​
If the measure lands between two numbers your size is a half size Ex: Between 5 and 6 ring size: 5.5. If half sizes are not available, order the next largest size.
​
If you are buying a ring as a surprise, you ideally need to find out their ring size. You can do this with a bit of careful detective work (ask around, drop some subtle hints). Or perhaps use the ring sizer when the person is asleep (don’t laugh we have known this to happen!). Failing this, however, you could take a ring to a jeweller’s for sizing.
