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

Light Blue is a light blue with a blue (cool) undertone and a calculated LRV of 61. Against white trim the contrast ratio is 1.43:1, which gives almost no contrast, so the molding reads through shadow alone (a tone-on-tone look); painted tone-on-tone, the arched pattern shows only through its shadow lines.

Arched layout on a 10 ft office 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. A molding wall behind the desk doubles as a video-call backdrop.

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 Light Blue

Blues work best fully drenched: wall, molding and chair rail in one color, with a slightly higher sheen on the trim.

Questions

How much molding do I need for a 10 ft office 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 Light Blue warm or cool?

Light Blue has a blue (cool) undertone and reads as a light blue. Its calculated LRV is 61, so it reflects a lot of light and keeps molding shadows soft.

Should trim be the same color as Light Blue walls?

Painting the molding the same color gives a modern, tone-on-tone finish where only shadows show the pattern. White trim adds almost no contrast, so the molding reads through shadow alone (a tone-on-tone look) (1.43:1), and black trim gives 10.36:1.

How high should the chair rail be in a office?

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. A molding wall behind the desk doubles as a video-call backdrop.
