You want to hang your new picture, but how high?
A rule of thumb is to hang your picture at eye level.
You went to a dinner party and saw pictures that look way too high? Why?
This is very common in a dining area. What's happenig is your eye level is higher walking in the hallway than sitting in the dining room.
Hallway pictures should be hung higher than living and dining room pictures or anywhere else you spend your time seated.
How should your new picture hang in relation to other pictures in the room?
You can line them horizontally level by their tops, middles, or bottoms depending on what looks best. Vertically, line pictures up by their centers.
