SW Sleepy Blue Board and Batten Wall Molding: wall elevation, color data (LRV 57.9), living room layout for 12, 15, 18 ft walls, cut list, calculator and pre-
Project calculator
Overview
SW Sleepy Blue is a light gray with a blue (cool) undertone and a calculated LRV of 57.9. Against white trim the contrast ratio is 1.5:1, 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 Sleepy Blue
Grays sit in the middle of the contrast range: white trim reads clearly, while same-color trim gives a quiet, architectural look.

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 Sleepy Blue warm or cool?
SW Sleepy Blue has a blue (cool) undertone and reads as a light gray. Its calculated LRV is 57.9, so it sits in the mid range, where molding shadows show clearly.
Should trim be the same color as SW Sleepy Blue 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 (1.5:1), and black trim gives 9.87:1.
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.
