Wall molding linear-foot estimate

Estimate for rectangular molding frames.

Estimated quantity133.76 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

F&B Green Smoke is a mid-tone green with a green undertone and a calculated LRV of 19.2. Against white trim the contrast ratio is 3.9:1, which gives clear contrast; painted tone-on-tone, the double frame pattern shows only through its shadow lines.

Double Frame 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 6 frames per row, each 25.3 in wide, with 50 in upper and 21 in lower frames. The layout uses about 82.59 m of 2.5 cm molding, or 35 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 double frame pattern

The inner outline sits 1.5 in inside the outer one. Cut a 1.5 in spacer from an offcut and use it at every corner so the two lines stay parallel.

Painting molding in F&B Green Smoke

Greens are the most popular color for tone-on-tone molding walls: the shadows of the frames add depth without breaking the color.

Questions

How much molding do I need for a 15 ft living room wall with double frame frames?

About 82.59 m (271 linear ft) including a chair rail and 10% waste, which is 35 sticks of 240 cm. That assumes 6 frames per row, 25.3 in wide, on an 8 ft ceiling.

Is F&B Green Smoke warm or cool?

F&B Green Smoke has a green undertone and reads as a mid-tone green. Its calculated LRV is 19.2, so it absorbs light, so tone-on-tone molding reads as deep relief.

Should trim be the same color as F&B Green Smoke 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 (3.9:1), and black trim gives 3.8:1.

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.
