Wall molding linear-foot estimate

Estimate for rectangular molding frames.

Estimated quantity109.08 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 Caviar is a very dark black with a neutral undertone and a calculated LRV of 3. Against white trim the contrast ratio is 11.83:1, which gives strong, graphic contrast; painted tone-on-tone, the picture frame pattern shows only through its shadow lines.

Picture Frame layout on a 12 ft staircase 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 5 frames per row, each 24 in wide, with 50 in upper and 21 in lower frames. The layout uses about 37.27 m of 2.5 cm molding, or 16 sticks of 240 cm, including 10% waste. Frames follow the stair angle: keep the bottom rail parallel to the stringer.

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 SW Caviar

Near-black walls turn molding into pure relief; use a satin or semi-gloss on the trim so the profile catches light.

Questions

How much molding do I need for a 12 ft staircase wall with picture frame frames?

About 37.27 m (122 linear ft) including a chair rail and 10% waste, which is 16 sticks of 240 cm. That assumes 5 frames per row, 24 in wide, on an 8 ft ceiling.

Is SW Caviar warm or cool?

SW Caviar has a neutral undertone and reads as a very dark black. Its calculated LRV is 3, so it absorbs light, so tone-on-tone molding reads as deep relief.

Should trim be the same color as SW Caviar 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 (11.83:1), and black trim gives 1.25:1.

How high should the chair rail be in a staircase?

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. Frames follow the stair angle: keep the bottom rail parallel to the stringer.
