    Karen...Usually when you buy a door the frame is included.

    Take your measurements to your local home improvement store like Menards or Home Depot and they will set you up with what you need.

      Thanks, but I'm buying a used door and received the answer I was looking for. I should have been more clear with my question. Thanks for answering.l

    You don't fit a door to a rough opening you frame out the opening to fit the door. Most pre hung doors are standard sizes. You need to measure the opening and get a pre hung door the will fit the openig and shim it out as you plumb and level it. Keep in mind there are codes for entry (36"), bedroom (30"), bathroom (28" - 30"), and closet doors (24"-28").

      I want to put French doors at the top of my stairs. I can buy the doors used and refinish, but need to know what size to buy that will fit a rough opening of 37.5" X 8'

    Standard door height is 6' 8". Your opening of 37.5' wide a 36" door would work after framing. !x boards for the frame. You would also need to put in a header above the door for the height.

      Thank you, the doors I want to purchase are 36" X 7' and are a steal at $15, but need to be refinished. Hopefully I'll be able to get it done, soon. Thanks again.
