Balance is the Key
The most important thing to consider when choosing and hanging a mirror in a mudroom or foyer is balance. This keeps the entryway looking polished and well cohesive as it ties the whole room together.
Vertical Height
Let's make sure the height you choose is functional. Picture this you walk into an entryway and the mirror is too high to catch your reflection or is practically a tripping hazard. Hanging a mirror at the right hight isn't just about nailing it to the wall.
If you are hanging your mirror above a bench then don't place it too close to the bench as people will lean up against it causing it to smudge. Not to mention it could break.
If it's a full length mirror make sure it's away from the are where kids or guests will kick off their shoes. You don't want dirt and mud getting on it either.
It's generally preferred to hang at eye level if space permits this ensure that guests will be able to actual use the mirror. Consider the negative space around the mirror and ensure it's not too crammed up against any hooks, console table or other furniture.
The Centerline Rule
A common interior design rule for mirror height is The Centerline Rule, which suggests that the center of the mirror should be approximately 57 to 65 inches from the floor. This guideline ensures that the mirror is at an optimal height for average eye level and aligns with standard art-hanging principles.
