For a rough idea count on hanging your mirror approximately 57 to 65 inches off the floor.
Proper height for dining room mirror.
I also placed it at the same height as the picture above the buffet.
I miss not having a proper dining room pantry laundryoom but am grateful for what i do have.
Mirrors placed above headboards and couches require a 5 to 10 inch gap between the mirror and the item.
I do have a question though on hanging pictures.
My current home is small there is no dining room just an eat in kitchen area which is small.
Mirrors reflect light and make a room feel larger and when hung above furniture they act as stunning yet simple wall decor.
I like mirrors in any room of the house for the reason you mentioned it bounces light around the room.
Tips on hanging a mirror over furniture.
Focus on size shape and the.
If the height of your furniture is below 35 inches then an eight to 12 inch space is ideal.
Mirrors above toilets or near furniture not above furniture should abide by the same rule.
One is above a 33 buffet which i placed it 10 inches above and it looks great.
I just hung 2 pictures in my dining room.
The second companion picture is on a wall that has nothing else on it or under it.
Arrangements of multiple mirrors on the same wall space should have the center of their arrangement set at 60 to 62 inches as well.
Well since you asked.
