Typically the baseboards are larger than casings… but balanced, you wouldn’t use a 8″ base with 3 1/4 casing for example, but it is larger.
It is classically driven and based in history, the golden rule for example by the Greeks. Balance & proportion.
Quote:
“A base molding, for example, does more than just conceal a joint; first, it serves as a visual foot to the weight of the wall that rises above it; second, it MODULATES the transition between the vertical and horizontal planes of wall and floor; third, it PUNCTUATES the bottom of a wall to signal it has come to an end.”
