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

Gray is a mid-tone gray with a neutral undertone and a calculated LRV of 32.2. Against white trim the contrast ratio is 2.54:1, which gives soft 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 Gray

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 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 Gray warm or cool?

Gray has a neutral undertone and reads as a mid-tone gray. Its calculated LRV is 32.2, so it sits in the mid range, where molding shadows show clearly.

Should trim be the same color as Gray 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 (2.54:1), and black trim gives 5.84:1.

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.
