Wall molding linear-foot estimate

Estimate for rectangular molding frames.

Estimated quantity50.93 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

Two parallel outlines 1.5 in apart, so each frame reads as one wide molding. It looks heavier than a single frame without a bigger profile. A bolder outline when a single 2.5 cm frame looks too light.

Double Frame 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 6 frames per row, each 25.3 in wide, 21 in tall. The layout uses about 34.09 m of 2.5 cm molding, or 15 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 double frame pattern

The inner outline sits 1.5 in inside the outer one. Cut a 1.5 in spacer from an offcut and use it at every corner so the two lines stay parallel.

Questions

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

About 34.09 m (112 linear ft) including a chair rail and 10% waste, which is 15 sticks of 240 cm. That assumes 6 frames per row, 25.3 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.
