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

SW Pure White is a white with a green undertone and a calculated LRV of 83.7. Against white trim the contrast ratio is 1.07:1, which gives almost no contrast, so the molding reads through shadow alone (a tone-on-tone look); painted tone-on-tone, the picture frame pattern shows only through its shadow lines.

Picture Frame 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 5 frames per row, each 24 in wide, with 50 in upper and 21 in lower frames. The layout uses about 37.27 m of 2.5 cm molding, or 16 sticks of 240 cm, including 10% waste. Align the middle frame with the headboard so the bed wall reads as one composition.

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.

Painting molding in SW Pure White

Whites show molding through shadow only, so side light (a window or wall sconce) brings the pattern out. Use satin on trim and eggshell on the wall to add a slight sheen difference.

Questions

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

About 37.27 m (122 linear ft) including a chair rail and 10% waste, which is 16 sticks of 240 cm. That assumes 5 frames per row, 24 in wide, on an 8 ft ceiling.

Is SW Pure White warm or cool?

SW Pure White has a green undertone and reads as a white white. Its calculated LRV is 83.7, so it reflects a lot of light and keeps molding shadows soft.

Should trim be the same color as SW Pure White walls?

Painting the molding the same color gives a modern, tone-on-tone finish where only shadows show the pattern. White trim adds almost no contrast, so the molding reads through shadow alone (a tone-on-tone look) (1.07:1), and black trim gives 13.93:1.

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.
