Get Smart was one of my favorite tv shows of all time. I believe on the show he said that he was 5-9, which leads me to believe he was no taller than 5-8.

Don was short, but not on talent. He was no more than 5'7".

I can see issues with Barbara's high eye line and Don's larger head. Barbara looked taller for more reasons than just pure height. Click Here

Saw Adams in L. A. in the early 90's. He's a very short man, approximately 5'6.5" tops.

At Ray Courts' North Hollywood show in the 90's a few times, he isn't 5' 8.75", I'd go 5' 7.5" tops. Barbara Feldon was in stocking feet & he in lifts for the entire run of the show. On a blooper reel he admits his lifts are killing him.
