There are a few things to keep in mind when hanging a large mirror in a dining room. The mirror should be hung at eye level, and the center of the mirror should be at least 4 feet above the ground. It is also important to make sure that the mirror is hung level.
To hang the mirror, first find the studs in the wall using a stud finder. Then mark the location of the studs on the wall with a pencil. Next, use a drill to make pilot holes in the wall at the marks for the studs. Finally, use screws to secure the mirror to the wall.
