To buy a ring, the first thing is to confirm the size of it. How to confirm the size maybe a problem to most people!
1.Use a rope to circle the ring finger. Lightly circle it from the end of the finger. The rope circle should not be too loose. Slightly loose is okay.
2.Use a pen to make a mark the rope where it meets the beginning end to measure the size.
3.Measure the rope from the its beginning to the end to measure the length.
To make the result more exact, the mm should be very accurate.
4.Search some information on the size of ring, to compare the search result with the measure result.
5.Choose a ring whose size is most close to your finger size,one size bigger than your own is highly recommended.
