Wall molding linear-foot estimate

Estimate for rectangular molding frames.

Estimated quantity109.08 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 12 ft dining room 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 5 frames per row, each 24 in wide, with 50 in upper and 21 in lower frames. The layout uses about 67.17 m of 2.5 cm molding, or 28 sticks of 240 cm, including 10% waste. Check that the chair rail clears chair backs, usually 32 to 36 in.

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 12 ft dining room wall with double frame frames?

About 67.17 m (220 linear ft) including a chair rail and 10% waste, which is 28 sticks of 240 cm. That assumes 5 frames per row, 24 in wide, on an 8 ft ceiling.

How high should the chair rail be in a dining 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. Check that the chair rail clears chair backs, usually 32 to 36 in.
