White Dining Room Accent Wall Molding
White Dining Room Accent Wall Molding: wall elevation, color data (LRV 89.5), dining room layout for 10, 12, 14 ft walls, cut list, calculator and pre-cut kit
Project calculator
Overview
White is a white with a neutral undertone and a calculated LRV of 89.5. Against white trim the contrast ratio is 1:1, 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 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 37.27 m of 2.5 cm molding, or 16 sticks of 240 cm, including 10% waste. Check that the chair rail clears chair backs, usually 32 to 36 in.
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 White
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 12 ft dining room wall with picture frame frames?
About 37.27 m (122 linear ft) including a chair rail and 10% waste, which is 16 sticks of 240 cm. That assumes 5 frames per row, 24 in wide, on an 8 ft ceiling.
Is White warm or cool?
White has a neutral undertone and reads as a white white. Its calculated LRV is 89.5, so it reflects a lot of light and keeps molding shadows soft.
Should trim be the same color as White 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) (1:1), and black trim gives 14.84:1.
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.
