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

BM White Dove (OC-17) is a white with a green undertone and a calculated LRV of 85.2 (published LRV 83). Against white trim the contrast ratio is 1.05:1, 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 staircase 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. Frames follow the stair angle: keep the bottom rail parallel to the stringer.

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 BM White Dove

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 staircase 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.

Is BM White Dove warm or cool?

BM White Dove has a green undertone and reads as a white white. Its calculated LRV is 85.2, so it reflects a lot of light and keeps molding shadows soft.

Should trim be the same color as BM White Dove 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) (1.05:1), and black trim gives 14.15:1.

How high should the chair rail be in a staircase?

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. Frames follow the stair angle: keep the bottom rail parallel to the stringer.
