Bottom of the TV frame is currently 23" to the bottom. It's on a livingroom end table presently and using the supplied stand. It seems pretty comfortable and can still go a little higher I think.
I've been in homes where the TV seems pretty high for me (and uncomfortable) I was just wondering if there was a rule of thumb on this.

Meanwhile I've been searching for a corner stand that will hold a 52" LCD. Not much selection. Some all glass units. Placing a center speaker in the future could be a challenge.
