8.0" - 8.5" (average 8.25") = 140/90

These pictures give an idea of the tail showing if your wrist is the "average" size indicated. If your wrist is 8.0" you'll have a bit more tail than shown here, if it's 8.5" you'll have a bit less.

Also remember: With the longer lengths the tail will curve to your wrist, so it won't stick out as much as shown here.
