Determining your ring size

Determine your size

  1. THOMAS SABO ring sizes are measured in millimeters. For example a size 44 is 44mm in circumference.
  2. You can determine your ring size with a soft measuring tape or piece of ribbon. To measure, place the measuring tape (or ribbon) around your finger and mark the end.
  3. Using a ruler, measure the marked cord to get your ring size.

If your finger size is between two sizes, choose the next size up. For example, if your finger measured 51mm, select a 52mm ring size.
