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

SW Accessible Beige is a light greige-taupe with a warm (yellow) undertone and a calculated LRV of 57.9. Against white trim the contrast ratio is 1.5:1, which gives soft contrast; painted tone-on-tone, the nested pattern shows only through its shadow lines.

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

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 SW Accessible Beige

Greige and taupe hide small gaps and uneven caulk lines well, which makes them forgiving on DIY molding.

Questions

How much molding do I need for a 12 ft staircase 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 SW Accessible Beige warm or cool?

SW Accessible Beige has a warm (yellow) undertone and reads as a light greige-taupe. Its calculated LRV is 57.9, so it sits in the mid range, where molding shadows show clearly.

Should trim be the same color as SW Accessible Beige walls?

Painting the molding the same color gives a modern, tone-on-tone finish where only shadows show the pattern. White trim adds soft contrast (1.5:1), and black trim gives 9.87:1.

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.
