Wall molding linear-foot estimate

Estimate for rectangular molding frames.

Estimated quantity77.22 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 Evergreen Fog is a mid-tone green with a green undertone and a calculated LRV of 30.4. Against white trim the contrast ratio is 2.67:1, which gives soft contrast; painted tone-on-tone, the arched pattern shows only through its shadow lines.

Arched 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 3 frames per row, each 34.7 in wide, with 50 in upper and 21 in lower frames. The layout uses about 25.63 m of 2.5 cm molding, or 11 sticks of 240 cm, including 10% waste. Long, narrow walls suit a repeating rhythm of equal frames.

Building the arched pattern

Arched tops are pre-formed in MDF; the straight sides and the bottom rail are cut to the same width as the arch. Fix the arch first, then hang the sides from it.

Painting molding in SW Evergreen Fog

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 10 ft hallway wall with arched frames?

About 25.63 m (84 linear ft) including a chair rail and 10% waste, which is 11 sticks of 240 cm. That assumes 3 frames per row, 34.7 in wide, on an 8 ft ceiling.

Is SW Evergreen Fog warm or cool?

SW Evergreen Fog has a green undertone and reads as a mid-tone green. Its calculated LRV is 30.4, so it sits in the mid range, where molding shadows show clearly.

Should trim be the same color as SW Evergreen Fog walls?

Painting the molding the same color gives a modern, tone-on-tone finish where only shadows show the pattern. White trim adds soft contrast (2.67:1), and black trim gives 5.55:1.

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.
