There are many factors to consider in choosing a tripod (weight of tripod, rated weight, stability, centre column, hook, ability to shoot at ground level, no. of sections, etc) all has its pro and cons.
If height is your only concern, than the factors related to height are:
1. your height
2. type of terrain (eg. slope, uneven)
If possible, get a tripod that is taller than you. This will allow you to mount it on slopes with one leg extended more than the others. A taller tripod also allow you to NOT extend the legs fully. Some people say this will increase the stability of the tripod.
A Gitzo 1227 as suggested by tOGGY is a great way to start.
Good luck!
