I have the same issue with suits. I'm 6 feet tall, near enough, but have a 29" inside leg. If I was in proportion I'd be 5'5" or 6'7". Shops often tell me that you have very short legs for your height sir, as if I had reached my current age without being aware of this. Consequently attempts to buy off the shelf suits result in trousers that are far too long, and jackets that fit perfectly across the shoulders but end at the navel.
Thankfully my local gentleman's outfitter offers free alterations and you can order online, so I don't need to be told once again about my very short legs.
