Wall molding linear-foot estimate

Estimate for rectangular molding frames.

Estimated quantity56.83 linear feet

Divide by 7.87 ft (240 cm stick) and round up for the number of sticks.

Formula & assumptionsframe_count * 2 * (frame_width_inches + frame_height_inches) / 12 * (1 + waste_percent / 100)

Assumes identical rectangular frames. The waste allowance is editable. The estimate does not optimize cuts or include separate rails, baseboards, or other trim.

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 arched pattern shows only through its shadow lines.

Arched layout on a 8 ft kitchen wall

Molding over the full wall height, upper and lower rows divided by a chair rail. On a 8 ft wall with an 8 ft ceiling this gives 2 frames per row, each 42 in wide, with 50 in upper and 21 in lower frames. The layout uses about 19 m of 2.5 cm molding, or 8 sticks of 240 cm, including 10% waste. Keep molding off the backsplash area and use a scrubbable paint finish.

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 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.

Questions

How much molding do I need for a 8 ft kitchen wall with arched frames?

About 19 m (62 linear ft) including a chair rail and 10% waste, which is 8 sticks of 240 cm. That assumes 2 frames per row, 42 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 kitchen?

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. Keep molding off the backsplash area and use a scrubbable paint finish.
