Bracelet Sizing Guidelines - How to determine your bracelet size
The best way to get a good fit is to measure a cuff bracelet you already have and compare the inside end-to-end measurement and the gap measurement with those of the bracelet you are considering purchasing.
If you don't have a cuff bracelet to use for comparison, then follow this method:
First measure your wrist where you want to wear the bracelet.
Then look at the bracelet you are interested in and add: the inside measurement from end to end plus the gap.
If the two measurements are fairly close, you're in business.
For example, if your wrist measures 7" and you are looking at a bracelet with a 5-3/4" inside circumference and a 1-1/4" gap, then the bracelet will probably fit. How well it will fit will depend on whether you like to wear your cuff bracelet tight or loose, alone or with other bracelets, in front of or behind the prominent bone on your wrist. Therefore, you may want to add 1/2 inch to 1 inch to the measurement depending upon these variables.
Many cuff bracelets are adjustable. They can be opened or closed up to about a 1/2 inch larger or smaller. The types that are not easily adjustable are those that are made from very thick, heavy silver or those with inlaid stones across the entire front and sides.
To adjust your bracelet, be very careful how you adjust it so you don't damage it. If you try to bend an area of your bracelet where there is a stone or inlay, the stone may pop out or the inlay may crack. Changing the underlying structure on an inlay bracelet, may cause the inlay to pop out immediately or at a later date.
