Project calculator
Overview
Off-White is a white warm white with a warm (yellow) undertone and a calculated LRV of 80.9. Against white trim the contrast ratio is 1.1:1, which gives almost no contrast, so the molding reads through shadow alone (a tone-on-tone look); painted tone-on-tone, the arched pattern shows only through its shadow lines.
Arched layout on a 12 ft bedroom 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 32.26 m of 2.5 cm molding, or 14 sticks of 240 cm, including 10% waste. Align the middle frame with the headboard so the bed wall reads as one composition.
Building the arched pattern
Arched tops are pre-formed in MDF; the straight sides and the bottom rail are cut to the same width as the arch. Fix the arch first, then hang the sides from it.
Painting molding in Off-White
Warm whites keep molding soft and traditional. Match the trim to the wall for a calm look, or use a cleaner white on trim to sharpen the outlines.

How much molding do I need for a 12 ft bedroom wall with arched frames?
About 32.26 m (106 linear ft) including a chair rail and 10% waste, which is 14 sticks of 240 cm. That assumes 4 frames per row, 31 in wide, on an 8 ft ceiling.
Is Off-White warm or cool?
Off-White has a warm (yellow) undertone and reads as a white warm white. Its calculated LRV is 80.9, so it reflects a lot of light and keeps molding shadows soft.
Should trim be the same color as Off-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) (1.1:1), and black trim gives 13.48:1.
How high should the chair rail be in a bedroom?
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. Align the middle frame with the headboard so the bed wall reads as one composition.
