Carpenter question

[Sal Lubrano]

Building a large storage closet. It will have two pairs of bi-fold doors on it. Two sets of 36'' doors for a total of 72''. My question is what do I frame the opening out to width and height? The doors are 80" high with an assembled height of 80.5''.

Assuming that those are the true measurements, I would add 3/4 to 1 inch to the width. The height can be tricky depending on the floor/ threshold and type of attaching hardware. Usually 1-1/2 to 2 inches added to the height is safe in most cases.
