Wall molding linear-foot estimate

Estimate for rectangular molding frames.

Estimated quantity47.85 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

A second, smaller frame set 4 in inside each outer frame using the same profile. It doubles the shadow lines and gives a classic, layered look. Layered depth for traditional, French and formal rooms.

Nested layout on a 15 ft living room wall

Molding on the lower third of the wall under a chair rail; the upper wall stays plain. On a 15 ft wall with an 8 ft ceiling this gives 5 frames per row, each 31.2 in wide, 21 in tall. The layout uses about 29.73 m of 2.5 cm molding, or 13 sticks of 240 cm, including 10% waste. Center the layout on the sofa or TV rather than the wall when furniture is off-center.

Building the nested pattern

Fix the outer frames first, then set each inner frame 4 in inside with spacer blocks so the reveal is identical on all four sides. Both frames use the same 2.5 cm profile.

Questions

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

About 29.73 m (98 linear ft) including a chair rail and 10% waste, which is 13 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.
