Measuring the Rough Opening Size

Start by measuring the width and height of your existing doorway. Use these dimensions as a starting point for your new door's rough opening size. The rough opening should be slightly larger than the door to accommodate the door frame. Typically, the opening is 2 inches wider and 2 inches taller than the intended door size.
