What was Benjamin Franklin's height?

Hello lotto cyn 

He was five feet nine or ten according to a leading historian, this
was based on studies of portraits painted of him during his life.

Hope this helps. 

p.s. there is also a life sized statue of him in Cape Cod, just be
careful to explain what you are doing to passers by before you take
his inside leg measurement !!

I found his autobiography, but it doesn't mention his height

I'm not sure if his height is available, but it might researchers
might be able to make a good guesstimate based on what's known about
others.  David McCullough's popular book on John Adams may have some
hints, particulary as John and Abigail were avid correspondents.

Jeff Shaara's background to the novel "Rise to Rebellion" cites
sources on George Washington as noting that he was 6'2" and 175 pounds
as a young adult.  As is well-known, Washington was very tall for the
period.  There's not much of physical description of Franklin by
Shaara -- but at least Washington gives us an upper bound.
