If I want to accomodate a standard 30" x 80" door prehung, what kind of
rough framing do I need to do to accomodate it?

I would assume the door is 30", the door jamb will add 3/8" on each side
to
make it 30-3/4" assuming a 1/2" of play to level and shim the door, I
should
frame it with a rough opening width of 31-1/4". Height wise, the door is
80", assume again a 3/4" jamb depth, plus another 1/2" for play, also
assume
a tiled flooring with thinset and tile to be 1/2", we have a total height
of
81-3/4". So the rough opening should be 31-1/4" x 81-3/4". Am I
correct?

Thanks in advance,

Frame interior doors named size plus 2" (a rough opening for a 2-6
door is 2-8). Standard header height is 82 1/2" although some
carpenters frame them at 82. 82 1/2 will allow plenty of room for
finished flooring.


Thank you very much!
