Admittedly, most tents are on the small side of the spectrum. If you're a tall person, it can be easy to feel cramped by the narrow width and short height, but I wouldn't go so far as to say you'll feel claustrophobic. That is, unless you're already prone to those feelings. Thankfully, most tall tents do a good job at accommodating people over 6 feet, like myself. If you can't stand completely upright, chances are you can get most of the way there. And with the space to move around freely like that, you won't feel claustrophobic in the slightest.
