Wall molding linear-foot estimate

Estimate for rectangular molding frames.

Estimated quantity97.53 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

SW Creamy is a white warm white with a warm (yellow) undertone and a calculated LRV of 81.2. 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 SW Creamy

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.

Questions

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 SW Creamy warm or cool?

SW Creamy has a warm (yellow) undertone and reads as a white warm white. Its calculated LRV is 81.2, so it reflects a lot of light and keeps molding shadows soft.

Should trim be the same color as SW Creamy 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 13.53:1.

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.
