A:Answer I also have a small wrist, about 6 inches. I purchased the Regular size (not the Large size).
The band that holds the device is easily adjusted; there are still 4 adjustment points left that I could tighten it further on my wrist. So, in terms of overall size, it should be ok for your wrist.
That said, what I found cumbersome is that the device itself (not the band) is a fairly broad and rigid size. Because my wrist is small, there are gaps on either side of that rigid structure where it doesn't meet skin. It's a little annoying, but it doesn't adversely affect how the device works for me. The green heart-rate monitors are in the middle of the device against my wrist, so they still find my heart rate.
