Frames, mirrors, shelves and TV units: the right heights and arrangements.

The decorator's simple rule: place the center of a frame 145-150 cm from the floor, at eye level. Exact heights above a sofa, a bed and in a gallery.

The method to compose a structured gallery wall: invisible grid, 5 cm between frames, an anchor point and paper templates before you drill.

The right mirror size and the right height, room by room: width, placement above a console, eye level, without getting it wrong.

The decorator's simple rule: screen center at 110 cm from the floor and a stand wider than the TV. Exact sizes by wall width.

The right heights to hang your shelves and a simple method to style them without clutter, with concrete measurements in centimeters.
