Wall molding linear-foot estimate

Estimate for rectangular molding frames.

Estimated quantity41.25 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

Single rectangles of 2.5 cm molding, evenly spaced. The most adaptable layout: it works on short and long walls and in any room. Clean outlines that suit modern and transitional rooms.

Picture Frame layout on a 12 ft dining room wall

Molding on the lower third of the wall under a chair rail; the upper wall stays plain. On a 12 ft wall with an 8 ft ceiling this gives 5 frames per row, each 24 in wide, 21 in tall. The layout uses about 16.6 m of 2.5 cm molding, or 7 sticks of 240 cm, including 10% waste. Check that the chair rail clears chair backs, usually 32 to 36 in.

Building the picture frame pattern

Each frame is four pieces of 2.5 cm molding with 45 degree miters. Set the frames out from the center of the wall, keep every gap equal, and let the margins at the corners match the gaps.

Questions

How much molding do I need for a 12 ft dining room wall with picture frame frames?

About 16.6 m (54 linear ft) including a chair rail and 10% waste, which is 7 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.
