Light Blue Dining Room Geometric Wall Molding
Light Blue Dining Room Geometric Wall Molding: wall elevation, color data (LRV 61), dining room layout for 10, 12, 14 ft walls, cut list, calculator and pre-c
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 geometric pattern shows only through its shadow lines.
Geometric 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 4 frames per row, each 31 in wide, with 50 in upper and 21 in lower frames. The layout uses about 55.27 m of 2.5 cm molding, or 24 sticks of 240 cm, including 10% waste. Check that the chair rail clears chair backs, usually 32 to 36 in.
Building the geometric pattern
Fix the outer frame, then run diagonals corner to corner. Each diagonal end is cut at the frame's angle; measure it once per frame size and reuse the cut.
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 12 ft dining room wall with geometric frames?
About 55.27 m (181 linear ft) including a chair rail and 10% waste, which is 24 sticks of 240 cm. That assumes 4 frames per row, 31 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.
