Why around windows and doors need a plan
Nested frames with stepped inner corners, the Parisian apartment look. Corners are cut as small square returns rather than a plain miter. Treat the window or door casing as a fixed edge and lay frames out from it.
Building the french pattern
French panels add stepped inner corners: small square returns cut from the same molding replace the plain inner miter. Mark the corner squares with a template before fixing.

How much molding do I need for a 15 ft living room wall with french frames?
About 84.04 m (276 linear ft) including a chair rail and 10% waste, which is 36 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.
