BM Simply White Living Room Board and Batten Wall Molding: wall elevation, color data (LRV 92.5), living room layout for 12, 15, 18 ft walls, cut list, calcul
Project calculator
Overview
BM Simply White (OC-117) is a white with a green undertone and a calculated LRV of 92.5. Against white trim the contrast ratio is 1.03:1, which gives almost no contrast, so the molding reads through shadow alone (a tone-on-tone look); painted tone-on-tone, the board and batten pattern shows only through its shadow lines.
Board and Batten layout on a 15 ft living room wall
With battens every 16 in, a 15 ft wall takes 13 battens of 88 in plus a top rail: about 42.02 m of board including 10% waste. Center the layout on the sofa or TV rather than the wall when furniture is off-center.
Building the board and batten pattern
Fix the top rail level first, then hang the battens from it at 16 in spacing. Start from the center of the wall so the end gaps match.
Painting molding in BM Simply White
Whites show molding through shadow only, so side light (a window or wall sconce) brings the pattern out. Use satin on trim and eggshell on the wall to add a slight sheen difference.

How many battens for a 15 ft wall?
13 battens at 16 in spacing, plus a top rail across the 15 ft run.
Is BM Simply White warm or cool?
BM Simply White has a green undertone and reads as a white white. Its calculated LRV is 92.5, so it reflects a lot of light and keeps molding shadows soft.
Should trim be the same color as BM Simply White walls?
Painting the molding the same color gives a modern, tone-on-tone finish where only shadows show the pattern. White trim adds almost no contrast, so the molding reads through shadow alone (a tone-on-tone look) (1.03:1), and black trim gives 15.3:1.
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.
