In reply to Andy S:
It would help if you incuded this person actual height. I am 6'3" and I am tall but 7' is extremely tall.
On to your question I have a hilleberg Akto and it has an internal length of 220cm so pretty lon and other tents like the Anjan 2 are also reasonable weight for a one person tent but a litte bigger than an Akto. Hilleberg tents are expensive. So that may be a factor in the desicion making precess.
