What people usually misjudge
People usually over-focus on height
Height is the first thing your eye notices here, but height alone does not explain the whole comparison. Dime and Toothbrush also separate through footprint, thickness, or diameter once you stop treating them like flat outlines.
Volume usually diverges faster than intuition
Even when the silhouettes feel manageable, total occupied space can separate quickly. A rough volume estimate puts one toothbrush at about 131 dimes, which is why the bigger object can feel more dominant than a single dimension suggests.
The pairing works because it feels familiar
What makes this pairing useful is that both objects come from the same general world, so the contrast feels intuitive rather than exotic.
