Discard all local sizes for each country if it is too confusing. The most accurate and efficient way is to know the circumference of your finger then choose you accurate size using Noirdes sizings.

 

Tips

  1. Temperature is important

Don't measure when your body temperature is either too cold or too hot. A cold finger shrinks while a hot finger expands causing an inaccurate reading. Only measure when fingers are at room temperature.

 

  1. When two sizes seem to fit

If you hesitate between two sizes, always go with the larger one.

 

  1. A wider band needs a bigger size

If you consider purchasing a wide band, move up a size from your measurement, for comfort’s sake.

 

  1. Don't use strings

When measuring your finger, always refrain from using a string, they tend to stretch, which can result in wrong size. ALWAYS use a paper strip about 1/2 inch width.

 

  1. Big knuckles can affect your size

If your knuckle is a lot larger than the base of your finger, and you're using the virtual ruler, measure both the base of your finger and your knuckle and select a size in between the two.

 

  1. For best results, use a plain band

Extra wide band styles tend to run slightly small. If your borrowed ring has a narrower shaft than the one you wish to purchase, you may wish to order a ring a size larger than the normal size worn. Also, large stone rings may cause the shank to lift up when laid on its side on the display, slightly distorting the size measurements.
