I guess it could be understood even you think about it in your native language if he was depicted more. I mean something like this;
He is six foot ten, and a muscly man yet he's the first one to flee when he comes across even a slightest risk of danger.
I don't think that a man who is six foot two(~1,85) looks scary enough just because of his height. This is why in my example it is six foot ten.
P.S.:Elephant-mouse stories would be very depictive for your question.
