The Effect of Temperature on Ring Sizes
Please bear in mind that when your fingers are hot they are going to be a little larger than when cold. In winter the same finger can sometimes be up to 2 sizes smaller than in the summer. So when ascertaining your size it is best to take a measurement when the finger is cold and another when the finger is hot, using the average of the two sizes for everyday use.
