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

BM Simply White (OC-117) is a white with a green undertone and a calculated LRV of 92.5. Against white trim the contrast ratio is 1.03:1, which gives almost no contrast, so the molding reads through shadow alone (a tone-on-tone look); painted tone-on-tone, the nested pattern shows only through its shadow lines.

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.

Painting molding in BM Simply 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 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.

Is BM Simply White warm or cool?

BM Simply White has a green undertone and reads as a white white. Its calculated LRV is 92.5, so it reflects a lot of light and keeps molding shadows soft.

Should trim be the same color as BM Simply 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) (1.03:1), and black trim gives 15.3:1.

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.
