The question I get most when I work is "how should I hang my pictures". Now I thought I would give you some tips on just that, and at the bottom of the page also a tool for hanging pictures without measuring. Always start from yourself and what YOU want to see on the walls. Combining old and new, different frames perhaps? Dare to test yourself. Before you start nailing the walls, always plan the wall by laying out the pictures on the floor in a combination that you like. That is, if you want to make a cluster of motifs.
Do not hang art / pictures too high! A good measure is usually that you should be able to stand dormant and see the upper edge of the board, (about two steps from it). Many people place the pictures too high, but keep in mind that you usually sit down in a room, and in addition the ceiling height is better if the pictures do not sit too close to the ceiling.
