BM White Dove Staircase French Wall Molding: wall elevation, color data (LRV 85.2), staircase layout for 8, 12, 16 ft walls, cut list, calculator and pre-cut
Project calculator
Overview
BM White Dove (OC-17) is a white with a green undertone and a calculated LRV of 85.2 (published LRV 83). Against white trim the contrast ratio is 1.05:1, which gives almost no contrast, so the molding reads through shadow alone (a tone-on-tone look); painted tone-on-tone, the french pattern shows only through its shadow lines.
French layout on a 12 ft staircase 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 67.06 m of 2.5 cm molding, or 28 sticks of 240 cm, including 10% waste. Frames follow the stair angle: keep the bottom rail parallel to the stringer.
Building the french pattern
French panels add stepped inner corners: small square returns cut from the same molding replace the plain inner miter. Mark the corner squares with a template before fixing.
Painting molding in BM White Dove
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 staircase wall with french frames?
About 67.06 m (220 linear ft) including a chair rail and 10% waste, which is 28 sticks of 240 cm. That assumes 4 frames per row, 31 in wide, on an 8 ft ceiling.
Is BM White Dove warm or cool?
BM White Dove has a green undertone and reads as a white white. Its calculated LRV is 85.2, so it reflects a lot of light and keeps molding shadows soft.
Should trim be the same color as BM White Dove 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) (1.05:1), and black trim gives 14.15:1.
How high should the chair rail be in a staircase?
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. Frames follow the stair angle: keep the bottom rail parallel to the stringer.
