Emerald Green Staircase Geometric Wall Molding
Emerald Green Staircase Geometric Wall Molding: wall elevation, color data (LRV 12.6), staircase layout for 8, 12, 16 ft walls, cut list, calculator and pre-c
Project calculator
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 geometric pattern shows only through its shadow lines.
Geometric layout on a 12 ft staircase 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 55.27 m of 2.5 cm molding, or 24 sticks of 240 cm, including 10% waste. Frames follow the stair angle: keep the bottom rail parallel to the stringer.
Building the geometric pattern
Fix the outer frame, then run diagonals corner to corner. Each diagonal end is cut at the frame's angle; measure it once per frame size and reuse the cut.
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.

How much molding do I need for a 12 ft staircase wall with geometric frames?
About 55.27 m (181 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 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 staircase?
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. Frames follow the stair angle: keep the bottom rail parallel to the stringer.
