The selectable sizes are in the US formula.

Understanding the correct sizing for bracelets is essential for ensuring a comfortable and secure fit. 

Use a flexible measuring tape or a piece of string to measure your wrist size accurately. Wrap it around your wrist just above the wrist bone, ensuring it is snug but not tight. Mark the point where the tape or string overlaps, then measure the length with a ruler. This measurement will help you select the appropriate size from the chart above.
