How long is this strap?

The fabric part of the strap is 9" long which is a bit too long for me due to my small wrist. I do love the watch with its large face so I deal with the length. People notice it because of its stylish look and ask the brand. Even though the strap is a bit too long for me, I highly recommend the weekender.
