A "rough opening" is the term for the opening in a wall into which a door or window will be fitted. It is slightly larger than the outside of the frame of the door or window to give some tolerance (space) to install it and get it in the exact position and square. It is measured between the structure to which the door or window will be fixed, such as the studs or masonry.
The amount of tolerance between the frame and the structure varies depending on the type of construction and how accurately it is built, but is often in the order of 10mm all around the frame.
An air seal and expanding foam are sometimes installed into this gap , and linings or architraves, and claddings cover it.
Rough opening are 2" wider and 2-2 1/2" taller than than the door itself. 2/8" door needs a 2/10" wide opening.
The rough opening of an interior door is two inches wider than the width of the door and two inches higher than its height. Thus your rough opening width is 38". A typical interior door has a height of 80" which would require a rough opening height of 82" but check your door to ensure that is theheight.
Make your rough opening 2 1/2 inches larger on the width and height.
In most cases rough opening is 38 1/4x82 1/2.

If you don't have the door but know which one you want, go to the store and the door will normally have the rough opening size on the label.
