F&B Hague Blue Board and Batten Wall Molding: wall elevation, color data (LRV 7.1), living room layout for 12, 15, 18 ft walls, cut list, calculator and pre-c
Project calculator
Overview
F&B Hague Blue is a dark blue with a blue (cool) undertone and a calculated LRV of 7.1. Against white trim the contrast ratio is 7.79:1, 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 F&B Hague Blue
Blues work best fully drenched: wall, molding and chair rail in one color, with a slightly higher sheen on the trim.

How many battens for a 15 ft wall?
13 battens at 16 in spacing, plus a top rail across the 15 ft run.
Is F&B Hague Blue warm or cool?
F&B Hague Blue has a blue (cool) undertone and reads as a dark blue. Its calculated LRV is 7.1, so it absorbs light, so tone-on-tone molding reads as deep relief.
Should trim be the same color as F&B Hague Blue 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 (7.79:1), and black trim gives 1.9:1.
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.
