The height at which you should hang a mirror over a console table depends on several factors such as the size and shape of the mirror and the table, the height of the ceiling, and the overall style and design of the room. However, there are some general guidelines that you can follow:

Center the mirror: Position the mirror so that it is cantered over the console table.

Eye level: Hang the mirror at eye level so that it is easy to see your reflection without having to look up or down too much. The standard height for hanging a mirror is between 57 and 65 inches from the floor.

Proportions: Consider the proportions of the mirror and the table. A larger mirror may need to be hung higher, while a smaller mirror can be hung lower.

Room size: In a room with high ceilings, you may want to hang the mirror a bit higher to create a sense of balance and proportion.

Ultimately, the best height to hang a mirror over a console table will depend on your personal preference and the specific design of your room. It may be helpful to use painter’s tape or another temporary marking to experiment with different heights before drilling holes in the wall.
