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 Urbane Bronze is a dark gray with a warm (yellow) undertone and a calculated LRV of 8.1. Against white trim the contrast ratio is 7.21:1, which gives strong, graphic contrast; painted tone-on-tone, the double frame pattern shows only through its shadow lines.

Double Frame layout on a 12 ft staircase 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 67.17 m of 2.5 cm molding, or 28 sticks of 240 cm, including 10% waste. Frames follow the stair angle: keep the bottom rail parallel to the stringer.

Building the double frame pattern

The inner outline sits 1.5 in inside the outer one. Cut a 1.5 in spacer from an offcut and use it at every corner so the two lines stay parallel.

Painting molding in SW Urbane Bronze

Grays sit in the middle of the contrast range: white trim reads clearly, while same-color trim gives a quiet, architectural look.

Questions

How much molding do I need for a 12 ft staircase wall with double frame frames?

About 67.17 m (220 linear ft) including a chair rail and 10% waste, which is 28 sticks of 240 cm. That assumes 5 frames per row, 24 in wide, on an 8 ft ceiling.

Is SW Urbane Bronze warm or cool?

SW Urbane Bronze has a warm (yellow) undertone and reads as a dark gray. Its calculated LRV is 8.1, so it absorbs light, so tone-on-tone molding reads as deep relief.

Should trim be the same color as SW Urbane Bronze walls?

Painting the molding the same color gives a modern, tone-on-tone finish where only shadows show the pattern. White trim adds strong, graphic contrast (7.21:1), and black trim gives 2.06:1.

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.
