Overview
Single rectangles of 2.5 cm molding, evenly spaced. The most adaptable layout: it works on short and long walls and in any room. Clean outlines that suit modern and transitional rooms.
Picture Frame layout on a 15 ft living room wall
Molding over the full wall height, upper and lower rows divided by a chair rail. On a 15 ft wall with an 8 ft ceiling this gives 6 frames per row, each 25.3 in wide, with 50 in upper and 21 in lower frames. The layout uses about 45.82 m of 2.5 cm molding, or 20 sticks of 240 cm, including 10% waste. Center the layout on the sofa or TV rather than the wall when furniture is off-center.
Building the picture frame pattern
Each frame is four pieces of 2.5 cm molding with 45 degree miters. Set the frames out from the center of the wall, keep every gap equal, and let the margins at the corners match the gaps.

Questions
How much molding do I need for a 15 ft living room wall with picture frame frames?
About 45.82 m (150 linear ft) including a chair rail and 10% waste, which is 20 sticks of 240 cm. That assumes 6 frames per row, 25.3 in wide, on an 8 ft ceiling.
How high should the chair rail be in a living room?
About one third of the ceiling height: 32 in on an 8 ft ceiling, 36 in on 9 ft and 40 in on 10 ft. Center the layout on the sofa or TV rather than the wall when furniture is off-center.
