Wall molding linear-foot estimate

Estimate for rectangular molding frames.

Estimated quantity88.73 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 Mega Greige is a mid-tone greige-taupe with a warm (yellow) undertone and a calculated LRV of 36.9. Against white trim the contrast ratio is 2.26:1, which gives soft contrast; painted tone-on-tone, the picture frame pattern shows only through its shadow lines.

Picture Frame layout on a 10 ft hallway wall

Molding over the full wall height, upper and lower rows divided by a chair rail. On a 10 ft wall with an 8 ft ceiling this gives 4 frames per row, each 25 in wide, with 50 in upper and 21 in lower frames. The layout uses about 30.4 m of 2.5 cm molding, or 13 sticks of 240 cm, including 10% waste. Long, narrow walls suit a repeating rhythm of equal frames.

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 Mega Greige

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 10 ft hallway wall with picture frame frames?

About 30.4 m (100 linear ft) including a chair rail and 10% waste, which is 13 sticks of 240 cm. That assumes 4 frames per row, 25 in wide, on an 8 ft ceiling.

Is SW Mega Greige warm or cool?

SW Mega Greige has a warm (yellow) undertone and reads as a mid-tone greige-taupe. Its calculated LRV is 36.9, so it sits in the mid range, where molding shadows show clearly.

Should trim be the same color as SW Mega Greige 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 (2.26:1), and black trim gives 6.58:1.

How high should the chair rail be in a hallway?

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. Long, narrow walls suit a repeating rhythm of equal frames.
