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

Dusty Blue is a mid-tone blue with a blue (cool) undertone and a calculated LRV of 29. Against white trim the contrast ratio is 2.78:1, which gives soft contrast; painted tone-on-tone, the geometric pattern shows only through its shadow lines.

Geometric 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 43.87 m of 2.5 cm molding, or 19 sticks of 240 cm, including 10% waste. A molding wall behind the desk doubles as a video-call backdrop.

Building the geometric pattern

Fix the outer frame, then run diagonals corner to corner. Each diagonal end is cut at the frame's angle; measure it once per frame size and reuse the cut.

Painting molding in Dusty 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 geometric frames?

About 43.87 m (144 linear ft) including a chair rail and 10% waste, which is 19 sticks of 240 cm. That assumes 3 frames per row, 34.7 in wide, on an 8 ft ceiling.

Is Dusty Blue warm or cool?

Dusty Blue has a blue (cool) undertone and reads as a mid-tone blue. Its calculated LRV is 29, so it absorbs light, so tone-on-tone molding reads as deep relief.

Should trim be the same color as Dusty Blue 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 (2.78:1), and black trim gives 5.34:1.

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.
