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

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.

Why around outlets need a plan

Single rectangles of 2.5 cm molding, evenly spaced. The most adaptable layout: it works on short and long walls and in any room. Turn off power at the breaker before working near outlets.

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 15 ft living room wall with picture frame frames?

About 20.56 m (67 linear ft) including a chair rail and 10% waste, which is 9 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.
