Wall molding linear-foot estimate

Estimate for rectangular molding frames.

Estimated quantity122.28 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 Grizzle Gray is a dark gray with a neutral undertone and a calculated LRV of 12.8. Against white trim the contrast ratio is 5.3:1, which gives clear contrast; painted tone-on-tone, the french pattern shows only through its shadow lines.

French layout on a 15 ft living room wall

Molding over the full wall height, upper and lower rows divided by a chair rail. On a 15 ft wall with an 8 ft ceiling this gives 5 frames per row, each 31.2 in wide, with 50 in upper and 21 in lower frames. The layout uses about 84.04 m of 2.5 cm molding, or 36 sticks of 240 cm, including 10% waste. Center the layout on the sofa or TV rather than the wall when furniture is off-center.

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 Grizzle Gray

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 15 ft living room wall with french frames?

About 84.04 m (276 linear ft) including a chair rail and 10% waste, which is 36 sticks of 240 cm. That assumes 5 frames per row, 31.2 in wide, on an 8 ft ceiling.

Is SW Grizzle Gray warm or cool?

SW Grizzle Gray has a neutral undertone and reads as a dark gray. Its calculated LRV is 12.8, so it absorbs light, so tone-on-tone molding reads as deep relief.

Should trim be the same color as SW Grizzle Gray walls?

Painting the molding the same color gives a modern, tone-on-tone finish where only shadows show the pattern. White trim adds clear contrast (5.3:1), and black trim gives 2.8:1.

How high should the chair rail be in a living room?

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. Center the layout on the sofa or TV rather than the wall when furniture is off-center.
