This was not meant to hijack the thread but, for some reason pool players feel like they always have something smart to say. So since I am an idiot, I am just curious. Dry wall is made in 8', 10' and 12'. Now it is "widely" known that this is to accommodate various ceiling heights. If dry wall was meant to be hung horizontal then why don't they taper the short ends? In addition do you think that the 16" stud standard might have been to accommodate anything 4' wide or was that just some random number they came up with? I am dying to hear these responses from the professionals. You may do it differently in your state or city and I am sure there is no hard fast rule past commercial building but, what I can tell you is that a very, very large majority of drywall is hung vertically. And unfortunately in the 3D universe yes you do increase the seams when hung horizontally and I wont get into the simple math but, I am sure if you think about it a little you will figure that part out.
Regardless of all the garbage that gets thrown around by the AZ clowns on here, the room is turning out nice and I thank the OP for his contributions. I personally love these types of posts. I can do without the AZZmonkeys but I don't see that going away anytime soon.
To stop the thread derail I started a new thread here
