Light Blue Living Room Wainscoting: wall elevation, color data (LRV 61), living room layout for 12, 15, 18 ft walls, cut list, calculator and pre-cut kits.
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 picture frame pattern shows only through its shadow lines.
Picture Frame layout on a 15 ft living room wall
Molding on the lower third of the wall under a chair rail; the upper wall stays plain. On a 15 ft wall with an 8 ft ceiling this gives 6 frames per row, each 25.3 in wide, 21 in tall. The layout uses about 20.56 m of 2.5 cm molding, or 9 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 picture frame pattern
Each frame is four pieces of 2.5 cm molding with 45 degree miters. Set the frames out from the center of the wall, keep every gap equal, and let the margins at the corners match the gaps.
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.

How much molding do I need for a 15 ft living room wall with picture frame frames?
About 20.56 m (67 linear ft) including a chair rail and 10% waste, which is 9 sticks of 240 cm. That assumes 6 frames per row, 25.3 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 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.
