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

Terracotta is a mid-tone orange-brown with a warm (yellow) undertone and a calculated LRV of 23.1. Against white trim the contrast ratio is 3.37:1, which gives clear 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 Terracotta

Warm browns and terracottas suit board and batten and craftsman layouts; cream trim keeps them from feeling heavy.

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 Terracotta warm or cool?

Terracotta has a warm (yellow) undertone and reads as a mid-tone orange-brown. Its calculated LRV is 23.1, so it absorbs light, so tone-on-tone molding reads as deep relief.

Should trim be the same color as Terracotta walls?

Painting the molding the same color gives a modern, tone-on-tone finish where only shadows show the pattern. White trim adds clear contrast (3.37:1), and black trim gives 4.41:1.

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.
