He's definitely not shorter than 5'10 as he is taller than Michael C Hall

I met Desmond (well, walked passed him) awhile back when I was attending the school where they filmed the hole. Back then I was 5'10 and I can recall him being my height.

i'd say he could be anywhere between 5'10 and 5'11.. saw him in ghost ship and in the last scene he looks tall... not short

I'd say he's closer to 5'9".
