Wall molding linear-foot estimate

Estimate for rectangular molding frames.

Estimated quantity97.53 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. Traditional rooms (traditional and classic) typically use nested, french, picture frame layouts: Layered frames, a chair rail and contrasting white trim.

Nested layout on a 12 ft bedroom 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 4 frames per row, each 31 in wide, with 50 in upper and 21 in lower frames. The layout uses about 56.33 m of 2.5 cm molding, or 24 sticks of 240 cm, including 10% waste. Align the middle frame with the headboard so the bed wall reads as one composition.

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.

Traditional look

Layered frames, a chair rail and contrasting white trim. Recommended layouts: nested, french, picture frame.

Questions

How much molding do I need for a 12 ft bedroom wall with nested frames?

About 56.33 m (185 linear ft) including a chair rail and 10% waste, which is 24 sticks of 240 cm. That assumes 4 frames per row, 31 in wide, on an 8 ft ceiling.

How high should the chair rail be in a bedroom?

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. Align the middle frame with the headboard so the bed wall reads as one composition.
