Wall molding linear-foot estimate

Estimate for rectangular molding frames.

Estimated quantity52.43 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

Emerald Green is a dark blue with a blue (cool) undertone and a calculated LRV of 12.6. Against white trim the contrast ratio is 5.36:1, which gives clear contrast; painted tone-on-tone, the arched pattern shows only through its shadow lines.

Arched layout on a 7 ft bathroom wall

Molding over the full wall height, upper and lower rows divided by a chair rail. On a 7 ft wall with an 8 ft ceiling this gives 2 frames per row, each 36 in wide, with 50 in upper and 21 in lower frames. The layout uses about 17.47 m of 2.5 cm molding, or 8 sticks of 240 cm, including 10% waste. Use moisture-resistant polystyrene outside the shower spray zone and a bathroom-rated paint.

Building the arched pattern

Arched tops are pre-formed in MDF; the straight sides and the bottom rail are cut to the same width as the arch. Fix the arch first, then hang the sides from it.

Painting molding in Emerald Green

Blues work best fully drenched: wall, molding and chair rail in one color, with a slightly higher sheen on the trim.

Questions

How much molding do I need for a 7 ft bathroom wall with arched frames?

About 17.47 m (57 linear ft) including a chair rail and 10% waste, which is 8 sticks of 240 cm. That assumes 2 frames per row, 36 in wide, on an 8 ft ceiling.

Is Emerald Green warm or cool?

Emerald Green has a blue (cool) undertone and reads as a dark blue. Its calculated LRV is 12.6, so it absorbs light, so tone-on-tone molding reads as deep relief.

Should trim be the same color as Emerald Green walls?

Painting the molding the same color gives a modern, tone-on-tone finish where only shadows show the pattern. White trim adds clear contrast (5.36:1), and black trim gives 2.77:1.

How high should the chair rail be in a bathroom?

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. Use moisture-resistant polystyrene outside the shower spray zone and a bathroom-rated paint.
