Lee ,
overall I would guess around 5'6" . The top would hit me about in the nose. I think a wading staff should hit no lower than your chin but no taller than you are. i joke about the water marks on it but its a good idea to mark a few inches lower than the top of your waders !! I got screwed up knees so most of the time I have some type of walking stick when in the woods, water or not.
If I get a chance I'll scan the pattern and post it up. I did 3 patterns , all a little different, Thats the one the wife liked the most so I did it first.
Go to the local chain store and look at the closet rods , then cut to length.
JUST REMEMBER........HAVE FUN !
