I'm exactly 7". Either regular or short works good for me. Wrist size...get your minds out of the gutter people! gatorcpa
I'm 6.75" and use standard length straps. However, I've noticed that some manufacturers (in their OEM straps), such as Nomos and (recently so I've heard) Panerai are "super-sizing" their straps. I had to add an extra hole in my "regular length" Nomos shell cordovan strap. Or maybe Germans have bigger wrists!
