Does the style of a ring affect my ring size?

Rings which have a deep band width will need to be slightly larger than your normal rings so do consider this when checking your size. For the most accurate reading, don’t measure cold fingers, which is when fingers are at their smallest. It’s best to measure the finger at the end of the day when the finger is at its largest. After sliding the ring sizer on, make sure it slides off fairly easily over the knuckle.
