Light Blue Dining Room Herringbone Wall Molding
Light Blue Dining Room Herringbone Wall Molding: wall elevation, color data (LRV 61), dining room layout for 10, 12, 14 ft walls, cut list, calculator and pre
Project calculator
Overview
Light Blue is a light blue with a blue (cool) undertone and a calculated LRV of 61. Against white trim the contrast ratio is 1.43:1, 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 12 ft dining room wall
Molding over the full wall height, upper and lower rows divided by a chair rail. On a 12 ft wall with an 8 ft ceiling this gives 5 frames per row, each 24 in wide, with 50 in upper and 21 in lower frames. The layout uses about 61.83 m of 2.5 cm molding, or 26 sticks of 240 cm, including 10% waste. Check that the chair rail clears chair backs, usually 32 to 36 in.
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 Light Blue
Blues work best fully drenched: wall, molding and chair rail in one color, with a slightly higher sheen on the trim.

Questions
How much molding do I need for a 12 ft dining room wall with herringbone frames?
About 61.83 m (203 linear ft) including a chair rail and 10% waste, which is 26 sticks of 240 cm. That assumes 5 frames per row, 24 in wide, on an 8 ft ceiling.
Is Light Blue warm or cool?
Light Blue has a blue (cool) undertone and reads as a light blue. Its calculated LRV is 61, so it reflects a lot of light and keeps molding shadows soft.
Should trim be the same color as Light Blue 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) (1.43:1), and black trim gives 10.36:1.
How high should the chair rail be in a dining 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. Check that the chair rail clears chair backs, usually 32 to 36 in.
