may be 5'11". guns was nothing without him, and since he wrote most of the songs it was best they didnt release any original material after he left. VERY talented song writer

I wonder if he seemed an inch shorter than Shatner in Star Trek because Doohan didn't wear lifts. Because he did seem shorter.

Here's Doohan in 1969 next to 5'10.5" DeForest Kelley:

And here's in 1992 with 5'7" LeVar Burton:

I think he was a solid 5'9" (or 5'8.5") during the original Star Trek, and shrunk to only a very little over 5'7" in his older days.
