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

Upper frames finish in a half-round arch instead of a flat top. The curve softens a headboard or reading-nook wall. Soft curves behind beds, in nurseries and entryways.

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.

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.

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.
