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. Donut and Toilet Paper Roll 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 toilet paper roll at about 4 donuts, which is why the bigger object can feel more dominant than a single dimension suggests.
Key insight
Treat this as a shape swap, not a huge scale jump. Donut and Toilet Paper Roll 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. The gap shows up most clearly in height, so the pairing feels vertical before it feels mathematical.
