In the movies House of 1000 Corpses and The Devil's Rejects there is a mugshot showing Sid at 6ft4 but he could have shrunk to 6ft2 in the Devil's Rejects he wore boots with what looked like a normal heel seemed to be a good inch shorter than 6ft5 Ken Foree

Haig appeared to be approximately 6'3" back in the 1970's when he was on Mary Hartman.

I would say 6 foot 2 is about right if you look in House of 1000 Corpses he seemed to be like he says 6 ft 4 235 pound part maybe i would say 220 in House in Devils Rejects in the first scene he looked like a strong 6 ft 4 when he just woke up and when he met Ken who is 6 ft 5 he looked a good inch short and i could believe a 235 in Rejects but then again he is still tall so he looks alot thinner even though he weighs alot at a horror conference though he looked like 6 ft 3 next to Ken my guess he lost 2 inches
