Wall molding linear-foot estimate

Estimate for rectangular molding frames.

Estimated quantity88.73 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 Iron Ore is a dark gray with a neutral undertone and a calculated LRV of 5.6. Against white trim the contrast ratio is 8.92:1, which gives strong, graphic contrast; painted tone-on-tone, the nested pattern shows only through its shadow lines.

Nested layout on a 10 ft hallway wall

Molding over the full wall height, upper and lower rows divided by a chair rail. On a 10 ft wall with an 8 ft ceiling this gives 4 frames per row, each 25 in wide, with 50 in upper and 21 in lower frames. The layout uses about 50.29 m of 2.5 cm molding, or 21 sticks of 240 cm, including 10% waste. Long, narrow walls suit a repeating rhythm of equal frames.

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 Iron Ore

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 10 ft hallway wall with nested frames?

About 50.29 m (165 linear ft) including a chair rail and 10% waste, which is 21 sticks of 240 cm. That assumes 4 frames per row, 25 in wide, on an 8 ft ceiling.

Is SW Iron Ore warm or cool?

SW Iron Ore has a neutral undertone and reads as a dark gray. Its calculated LRV is 5.6, so it absorbs light, so tone-on-tone molding reads as deep relief.

Should trim be the same color as SW Iron Ore 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 (8.92:1), and black trim gives 1.66:1.

How high should the chair rail be in a hallway?

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. Long, narrow walls suit a repeating rhythm of equal frames.
