Ted was an easy 6'9" would be my guess, that's why he was cast if the kind of roles he was. Compare hie Lurch (played in what look like normal shoes) to Fred Gwynne as Herman Munster, the producers felt the need to put 6'5" Fred in 4"ish block shoes to make him tower above everyone else, not so for Ted.
You have to remember Ted was not just an unusually tall guy he was an "acromegalic giant", his growth caused by a fault in his pituitary gland. This would have caused his hands, feet, ears, nose and facial bones to continue growing, giving the characteristic 'look' also seen in Richard Kiel and Andre the Giant.
Best comparison pic I kind find is from the Monkees where he dwarfs 5'8" Peter Tork by at least a foot. Remember Mike Nesmith (in the foreground, so not so close to Ted)was the tallest Monkee at peak 6'1"!

When you get to the heights of 6'5 1/2-6'10ish it is easy to exagerate and inflate height by 2 - 3 inches. the simple fact is most humans are between 5'0-6'2. so a 6'7 man claiming 6'9 or 6'10 isnt as outrageous as it may seem. a 6'1 man claiming 6'4 is unbelievable.

A rare photo of him as a young man barefoot on a beach while he was a lifeguard. C'mon he aint under 6'7" Lord Zeus. To me he looks a genuine 6 ft 8-6 ft 9". What do you think Rob? I know we don't know the other people's heights but in terms of proportions he does look close to this I think, I'd say 6 ft 8 barefoot.

After seeing Ted in an episode of 1972's "Banecek" last night, I think he was 6'7" max. There is a long scene where he walks alongside 6' George Peppard on flat ground, with both of them wearing flat heeled shoes. Peppard's eyes are at Ted's shoulder level, not the huge difference in height I was expecting to see. In the "Addams Family", Ted never really towered over tall guest actors such as 6'3" Frank Wilcox and (near) 6'2" Richard Deacon. And he may have used lifts to make "Lurch" look more imposing. I've seen him many times in normal roles playing the imposing "big guy", and he never seemed 6'9". He did good work in his "short" career, dying at just 46.

Robert Justman and Herb Solow wrote in Inside Star Trek: The Real Story that "the built-up Cassidy stood 7 feet tall" (in the episode What are Little Girls Made Of?).

Looking at his footwear in the episode, those extra 3 inches are quite noticable:
