French Door Rough Opening Widths

When calculating the rough opening width, you’ll need to add a bit to the actual door width:

  1. Take the single-door width
  2. Double for two doors
  3. Add 2 inches

For example, if each door is 36 inches wide:

  • 36 inches x 2 = 72 inches
  • Plus 2 inches = 74-inch rough opening

Having the proper rough opening width allows room for installation and smooth operation.
