SW Alabaster Living Room Chair Rail Molding
SW Alabaster Living Room Chair Rail Molding: wall elevation, color data (LRV 82.2), living room layout for 12, 15, 18 ft walls, cut list, calculator and pre-c
Project calculator
Overview
SW Alabaster is a white with a warm (yellow) undertone and a calculated LRV of 82.2. Against white trim the contrast ratio is 1.08:1, 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
A single horizontal rail at one third of the wall height, often used to split two paint colors. 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 5.03 m of 2.5 cm molding, or 3 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 SW Alabaster
Whites show molding through shadow only, so side light (a window or wall sconce) brings the pattern out. Use satin on trim and eggshell on the wall to add a slight sheen difference.

How much molding do I need for a 15 ft living room wall with picture frame frames?
About 5.03 m (17 linear ft) including a chair rail and 10% waste, which is 3 sticks of 240 cm. That assumes 6 frames per row, 25.3 in wide, on an 8 ft ceiling.
Is SW Alabaster warm or cool?
SW Alabaster has a warm (yellow) undertone and reads as a white white. Its calculated LRV is 82.2, so it reflects a lot of light and keeps molding shadows soft.
Should trim be the same color as SW Alabaster 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) (1.08:1), and black trim gives 13.69:1.
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.
