Wall molding linear-foot estimate

Estimate for rectangular molding frames.

Estimated quantity122.28 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

Nested frames with stepped inner corners, the Parisian apartment look. Corners are cut as small square returns rather than a plain miter. Parisian, Haussmann-style walls in bedrooms and living rooms.

Why around outlets need a plan

Nested frames with stepped inner corners, the Parisian apartment look. Corners are cut as small square returns rather than a plain miter. Turn off power at the breaker before working near outlets.

Building the french pattern

French panels add stepped inner corners: small square returns cut from the same molding replace the plain inner miter. Mark the corner squares with a template before fixing.

Questions

How much molding do I need for a 15 ft living room wall with french frames?

About 84.04 m (276 linear ft) including a chair rail and 10% waste, which is 36 sticks of 240 cm. That assumes 5 frames per row, 31.2 in wide, on an 8 ft ceiling.

How high should the chair rail be in a living room?

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. Center the layout on the sofa or TV rather than the wall when furniture is off-center.
