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. Traditional rooms (traditional and classic) typically use nested, french, picture frame layouts: Layered frames, a chair rail and contrasting white trim.
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.
Traditional look
Layered frames, a chair rail and contrasting white trim. Recommended layouts: nested, french, picture frame.

Questions
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.
