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 Iron Ore is a dark gray with a neutral undertone and a calculated LRV of 5.6. Against white trim the contrast ratio is 8.92:1, which gives strong, graphic contrast; painted tone-on-tone, the french pattern shows only through its shadow lines.

French 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 67.06 m of 2.5 cm molding, or 28 sticks of 240 cm, including 10% waste. Align the middle frame with the headboard so the bed wall reads as one composition.

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 SW Iron Ore

Grays sit in the middle of the contrast range: white trim reads clearly, while same-color trim gives a quiet, architectural look.

Questions

How much molding do I need for a 12 ft bedroom 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 SW Iron Ore warm or cool?

SW Iron Ore has a neutral undertone and reads as a dark gray. Its calculated LRV is 5.6, so it absorbs light, so tone-on-tone molding reads as deep relief.

Should trim be the same color as SW Iron Ore walls?

Painting the molding the same color gives a modern, tone-on-tone finish where only shadows show the pattern. White trim adds strong, graphic contrast (8.92:1), and black trim gives 1.66:1.

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.
