SW Inkwell Board and Batten Wall Molding
SW Inkwell Board and Batten Wall Molding: wall elevation, color data (LRV 3.6), living room layout for 12, 15, 18 ft walls, cut list, calculator and pre-cut k
Project calculator
Overview
SW Inkwell is a very dark gray with a violet undertone and a calculated LRV of 3.6. Against white trim the contrast ratio is 10.99:1, which gives strong, graphic 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 Inkwell
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 Inkwell warm or cool?
SW Inkwell has a violet undertone and reads as a very dark gray. Its calculated LRV is 3.6, so it absorbs light, so tone-on-tone molding reads as deep relief.
Should trim be the same color as SW Inkwell walls?
Painting the molding the same color gives a modern, tone-on-tone finish where only shadows show the pattern. White trim adds strong, graphic contrast (10.99:1), and black trim gives 1.35:1.
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.
