Wall molding linear-foot estimate

Estimate for rectangular molding frames.

Estimated quantity68.42 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 Tricorn Black is a very dark black with a neutral undertone and a calculated LRV of 2.9. Against white trim the contrast ratio is 12.04:1, which gives strong, graphic contrast; painted tone-on-tone, the nested pattern shows only through its shadow lines.

Nested layout on a 8 ft kitchen wall

Molding over the full wall height, upper and lower rows divided by a chair rail. On a 8 ft wall with an 8 ft ceiling this gives 3 frames per row, each 26.7 in wide, with 50 in upper and 21 in lower frames. The layout uses about 39 m of 2.5 cm molding, or 17 sticks of 240 cm, including 10% waste. Keep molding off the backsplash area and use a scrubbable paint finish.

Building the nested pattern

Fix the outer frames first, then set each inner frame 4 in inside with spacer blocks so the reveal is identical on all four sides. Both frames use the same 2.5 cm profile.

Painting molding in SW Tricorn Black

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 8 ft kitchen wall with nested frames?

About 39 m (128 linear ft) including a chair rail and 10% waste, which is 17 sticks of 240 cm. That assumes 3 frames per row, 26.7 in wide, on an 8 ft ceiling.

Is SW Tricorn Black warm or cool?

SW Tricorn Black has a neutral undertone and reads as a very dark black. Its calculated LRV is 2.9, so it absorbs light, so tone-on-tone molding reads as deep relief.

Should trim be the same color as SW Tricorn Black 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 (12.04:1), and black trim gives 1.23:1.

How high should the chair rail be in a kitchen?

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. Keep molding off the backsplash area and use a scrubbable paint finish.
