Wall molding linear-foot estimate

Estimate for rectangular molding frames.

Estimated quantity97.53 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

Diagonal lines run corner to corner inside each panel, forming diamonds across the wall. Mid-Century rooms (mid-century modern) typically use geometric, board and batten layouts: Geometric lines and vertical rhythm in warm, saturated colors.

Geometric layout on a 12 ft bedroom wall

Molding over the full wall height, upper and lower rows divided by a chair rail. On a 12 ft wall with an 8 ft ceiling this gives 4 frames per row, each 31 in wide, with 50 in upper and 21 in lower frames. The layout uses about 55.27 m of 2.5 cm molding, or 24 sticks of 240 cm, including 10% waste. Align the middle frame with the headboard so the bed wall reads as one composition.

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.

Questions

How much molding do I need for a 12 ft bedroom wall with geometric frames?

About 55.27 m (181 linear ft) including a chair rail and 10% waste, which is 24 sticks of 240 cm. That assumes 4 frames per row, 31 in wide, on an 8 ft ceiling.

How high should the chair rail be in a bedroom?

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. Align the middle frame with the headboard so the bed wall reads as one composition.
