SW Sea Salt Herringbone Wall Molding
SW Sea Salt Herringbone Wall Molding: wall elevation, color data (LRV 63.3), living room layout for 12, 15, 18 ft walls, cut list, calculator and pre-cut kits
Project calculator
Overview
SW Sea Salt is a light gray with a green undertone and a calculated LRV of 63.3. Against white trim the contrast ratio is 1.38:1, which gives almost no contrast, so the molding reads through shadow alone (a tone-on-tone look); painted tone-on-tone, the herringbone pattern shows only through its shadow lines.
Herringbone layout on a 15 ft living room wall
Molding over the full wall height, upper and lower rows divided by a chair rail. On a 15 ft wall with an 8 ft ceiling this gives 6 frames per row, each 25.3 in wide, with 50 in upper and 21 in lower frames. The layout uses about 76.93 m of 2.5 cm molding, or 33 sticks of 240 cm, including 10% waste. Center the layout on the sofa or TV rather than the wall when furniture is off-center.
Building the herringbone pattern
Chevrons are pairs of short pieces meeting at a point down the center of each panel. Keep the angle and the vertical spacing identical so the rows line up across frames.
Painting molding in SW Sea Salt
Grays sit in the middle of the contrast range: white trim reads clearly, while same-color trim gives a quiet, architectural look.

Questions
How much molding do I need for a 15 ft living room wall with herringbone frames?
About 76.93 m (252 linear ft) including a chair rail and 10% waste, which is 33 sticks of 240 cm. That assumes 6 frames per row, 25.3 in wide, on an 8 ft ceiling.
Is SW Sea Salt warm or cool?
SW Sea Salt has a green undertone and reads as a light gray. Its calculated LRV is 63.3, so it reflects a lot of light and keeps molding shadows soft.
Should trim be the same color as SW Sea Salt 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) (1.38:1), and black trim gives 10.73:1.
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.
