Overview
A second, smaller frame set 4 in inside each outer frame using the same profile. It doubles the shadow lines and gives a classic, layered look. Modern rooms (modern and minimalist) typically use picture frame, geometric, board and batten layouts: Flat profiles, fewer and larger frames, and trim painted the same color as the wall.
Nested 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 5 frames per row, each 31.2 in wide, with 50 in upper and 21 in lower frames. The layout uses about 70.63 m of 2.5 cm molding, or 30 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 nested pattern
Fix the outer frames first, then set each inner frame 4 in inside with spacer blocks so the reveal is identical on all four sides. Both frames use the same 2.5 cm profile.
Modern look
Flat profiles, fewer and larger frames, and trim painted the same color as the wall. Recommended layouts: picture frame, geometric, board and batten.

How much molding do I need for a 15 ft living room wall with nested frames?
About 70.63 m (232 linear ft) including a chair rail and 10% waste, which is 30 sticks of 240 cm. That assumes 5 frames per row, 31.2 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.
