Profile choice changes the entire feel of a wood wall or ceiling. Here's how the four most common profiles read in real installations.
S4S — Four Sides Square
Flat boards with square edges. Looks clean and modern when butt-jointed or shadow-gapped. Most flexible for unusual layouts.
V-Joint T&G
Tongue-and-groove with a beveled edge that forms a subtle V between boards. Reads traditional but timeless. The default for interior wood ceilings.
Nickel Gap T&G
Tongue-and-groove with a consistent ~1/8" reveal between boards. The current modern-architect favorite for walls and ceilings.

Fluted
Heavily ridged surface for dimensional shadow play. Best for accent walls and statement facades where the wall itself is the architecture.
