It's usually not a good idea to comment on someone's physical appearance like that. It doesn't matter if you were just stating a fact, or even if you meant it as a compliment and wish you were taller yourself. My best friend is very tall, and she hates it when people talk about her height. She's usually nice about it, but it makes her uncomfortable. So height might have been a touchy subject for your acquaintance, and it sounds like he took your comment as an insult and made a comment about you in return to show you how it feels when people talk about your height.
Height is one of those things about a person that isn't a choice and can't really be changed, so it's not something that should be commented on in most situations. Now if he'd had on a shirt you liked, or had bright green hair or something like that, that's the kind of thing that is usually okay to comment on. Height, weight, eye color, skin color, natural hair color, a medical condition or disability, etc. is usually not.
