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

BM Edgecomb Gray (HC-173) is a light greige-taupe with a warm (yellow) undertone and a calculated LRV of 65.3 (published LRV 63). Against white trim the contrast ratio is 1.34:1, which gives almost no contrast, so the molding reads through shadow alone (a tone-on-tone look); painted tone-on-tone, the picture frame pattern shows only through its shadow lines.

Picture 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 45.82 m of 2.5 cm molding, or 20 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 picture frame pattern

Each frame is four pieces of 2.5 cm molding with 45 degree miters. Set the frames out from the center of the wall, keep every gap equal, and let the margins at the corners match the gaps.

Painting molding in BM Edgecomb Gray

Greige and taupe hide small gaps and uneven caulk lines well, which makes them forgiving on DIY molding.

Questions

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

About 45.82 m (150 linear ft) including a chair rail and 10% waste, which is 20 sticks of 240 cm. That assumes 6 frames per row, 25.3 in wide, on an 8 ft ceiling.

Is BM Edgecomb Gray warm or cool?

BM Edgecomb Gray has a warm (yellow) undertone and reads as a light greige-taupe. Its calculated LRV is 65.3, so it reflects a lot of light and keeps molding shadows soft.

Should trim be the same color as BM Edgecomb Gray 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) (1.34:1), and black trim gives 11.04:1.

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.
