Project calculator
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 nested pattern shows only through its shadow lines.
Nested layout on a 12 ft dining room 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. Check that the chair rail clears chair backs, usually 32 to 36 in.
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 Gray
Grays sit in the middle of the contrast range: white trim reads clearly, while same-color trim gives a quiet, architectural look.

How much molding do I need for a 12 ft dining room 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 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 dining room?
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. Check that the chair rail clears chair backs, usually 32 to 36 in.
