SW Mega Greige Board and Batten Wall Molding: wall elevation, color data (LRV 36.9), living room layout for 12, 15, 18 ft walls, cut list, calculator and pre-
Project calculator
Overview
SW Mega Greige is a mid-tone greige-taupe with a warm (yellow) undertone and a calculated LRV of 36.9. Against white trim the contrast ratio is 2.26:1, which gives soft contrast; 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 SW Mega Greige
Greige and taupe hide small gaps and uneven caulk lines well, which makes them forgiving on DIY molding.

How many battens for a 15 ft wall?
13 battens at 16 in spacing, plus a top rail across the 15 ft run.
Is SW Mega Greige warm or cool?
SW Mega Greige has a warm (yellow) undertone and reads as a mid-tone greige-taupe. Its calculated LRV is 36.9, so it sits in the mid range, where molding shadows show clearly.
Should trim be the same color as SW Mega Greige walls?
Painting the molding the same color gives a modern, tone-on-tone finish where only shadows show the pattern. White trim adds soft contrast (2.26:1), and black trim gives 6.58:1.
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.
