It depends on how you want it to fit, tight or loose. The inner circumference is 7 inches. The best thing you can do is get your favorite fitting bracelet and measure the inner diameter. If it's within 1/4"-1/2" of 7 inches this bracelet will fit the way that one does. Hope this helps!
The beads will not drop off as they are woven in with wire. The beads are glass so can be broken but it is rare, they aren't delicate, they are well-made and pretty durable.
