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. Deck of Cards and Shampoo Bottle 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 shampoo bottle at about 8 deck of cardses, which is why the bigger object can feel more dominant than a single dimension suggests.
Key insight
Treat Deck of Cards as the reference unit and Shampoo Bottle as the scene setter. Once that mental model clicks, the comparison stops being abstract and starts feeling physical.
