I think you mean 75" high and 95" wide? The height is from the bottom all the way to the top. If you use a regular traverse rod and have the top of the pleat about 1/4" to 1/2" above the top of the rod, then an 84" panel will have the rod around 8 3/4" above your door, which would work. Depending upon your ceiling height, you might want one even longer. You didn't say.
The width of the panel is the width at the top. The bottom is about 1.5 times wider, so the fullness is already sewn in. I found that buying two panels with each equal to half my width plus 4 or 5 inches overlap at the middle and 3 or 4 inches return at the end worked. This means that, when closed, the top of the panel is gently tight against the rod and the drape hangs below with nice sewn-in folds. Mine were plenty full when hung this way and didn't overwhelm the traverse rod when gathered for opening.
You need to add in the extra width at the sides for gathering the drape. I don't know what you want there, but as an example, if you wanted an extra 15" on each side to gather the drape, then your full width is 95+15+15=125". Half of that is 62 1/2". Add 4" for the return and 4" for the overlap and you have 70.5" for each side. That's a really good match to their 75" wide panel. So, you could get two 75" wide panels, *if* 15" to 20" is enough to gather on the sides. Just adjust your rod width to match. That would mean using a total rod length of about 134 inches. I'd make that a little shorter to give yourself some playing room. Maybe 132"? Lay it all out and make sure it works before you hang it, then you'll know.
The 84" long panel will fit over your door if it is 75" high but if your ceiling is higher or if you like having the rod higher, you can go with the 95". In an 8 foot ceiling, the 95" would put the curtain pretty much up against the ceiling. Hope this helps. I struggled figuring out what size to get because the information online from Penneys is confusing for this curtain. They never say that the fullness is already sewn in, which is the critical thing to know.
See my review of this about changing the direct of the pleats to get these to gather on a normal rod.
By the way if you plan to hang the curtain *below* the rod, e.g., from clips, then all my vertical numbers here are wrong and you'll have to recompute them. Double check everything here before you proceed. It could be wrong and is only meant to illustrate how the measurements worked on the curtains I received from Penney's
