Wall molding linear-foot estimate

Estimate for rectangular molding frames.

Estimated quantity24.04 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

Navy Blue is a very dark purple with a violet undertone and a calculated LRV of 3.5. Against white trim the contrast ratio is 11.18:1, which gives strong, graphic contrast; painted tone-on-tone, the picture frame pattern shows only through its shadow lines.

Picture Frame layout on a 7 ft bathroom wall

Molding on the lower third of the wall under a chair rail; the upper wall stays plain. On a 7 ft wall with an 8 ft ceiling this gives 3 frames per row, each 22.7 in wide, 21 in tall. The layout uses about 9.67 m of 2.5 cm molding, or 5 sticks of 240 cm, including 10% waste. Use moisture-resistant polystyrene outside the shower spray zone and a bathroom-rated paint.

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 Navy Blue

Muted violets work tone-on-tone in bedrooms; keep the sheen low on the wall.

Questions

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

About 9.67 m (32 linear ft) including a chair rail and 10% waste, which is 5 sticks of 240 cm. That assumes 3 frames per row, 22.7 in wide, on an 8 ft ceiling.

Is Navy Blue warm or cool?

Navy Blue has a violet undertone and reads as a very dark purple. Its calculated LRV is 3.5, so it absorbs light, so tone-on-tone molding reads as deep relief.

Should trim be the same color as Navy Blue 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 (11.18:1), and black trim gives 1.33:1.

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.
