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. Toothbrush and Water 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 water bottle at about 15 toothbrushes, which is why the bigger object can feel more dominant than a single dimension suggests.
The pairing works because it feels familiar
Toothbrush and Water Bottle come from different parts of everyday life, which is why the comparison feels more like a change of setting than a small step up in size.
