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. Banana and Passport Book also separate through footprint, thickness, or diameter once you stop treating them like flat outlines.
Familiarity can distort the comparison
When one object is more familiar in daily life, people often use it as the default unit and either overstate or understate the gap. This pair works better when you compare occupied space directly instead of trusting whichever object feels more familiar.
Key insight
Treat this as a shape swap, not a huge scale jump. Banana and Passport Book 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.
