Orient Jewellers strongly recommends that you go to a professional jeweller to get your finger properly measured.
However if you must measure your finger at home, we recommend the following ring size guide.
Our Recommended Option: Measuring a Ring you own
Choose a ring that fits the finger you wish to wear the new ring comfortably.
We recommend that you do this in a warm afternoon when your fingers are at their largest due to the afternoon heat.
Place a ruler in the middle of your ring with the starting point ‘0’ at the inner side of the ring. Check against the table below to get your size.
