Hey all. . .

I'm in the planning phase of installing patio doors and wanted to ask what the generally accepted rough opening should be for a 5-foot wide set of French doors.

I know that ultimately, I'll have to follow the manufactuer's instructions, but I'm really just looking for a general number so I can make some sketches and determine other features to include in my renovation.

Thanks!

Kelly

I'm assuming you mean SWINGING French 5' patio doors and not SLIDING French 5' patio doors. There are two common rough opening widths: 5'0" or 5'2-3/4". Here's why:

Many manufacturers make a so-called 5' French door in which the rough opening is exactly 5'0" wide - but that means that the opening is 5'0", the door frame is approx. 4'11-1/4" and the doors are about 2'4" each.

The other way it's done is to have true 2'6" doors. So doing the math, the two 2'6" doors equal 5'0", plus another 1-1/2" for the frame, plus usually 1/2" or so for the astragal (it can vary), plus about 3/4" for the rough opening spacing = a rough opening of 5'2-3/4".

Again it can vary by an inch or so with some manufacturers.

As for the height, it also varies by manufacturer, but the common R.O. heights usually tend to be 6'8-1/2" (which is a shorter retrofit height for existing aluminum patio doors), 6'10" to 6'10-1/2" (these are the most common), and 8' to 8'2".
