It depends on the size watch you're using (i.e., the length from one spring bar to the other). If your watch length is 45mm, add that to the 158-165mm range, which gives you 203-210mm. Dividing by 25.4 mm/inch gives you 7.99" to 8.27".
I can't wear that type of mesh band because my wrist is less than 7" - - so I buy the style with removable mesh links (about $70).
Good luck!
