What people usually misjudge
Equal reach does not mean equal presence
People often flatten comparisons like this into a single end-to-end number. The more useful read is how one object stretches its size across span while the other turns more of its size into bulk, thickness, or visual heft.
Volume usually diverges faster than intuition
Even when the silhouettes feel manageable, total occupied space can separate quickly. A rough volume estimate puts one computer keyboard at about 12 passport books, which is why the bigger object can feel more dominant than a single dimension suggests.
Key insight
Treat Passport Book as the reference unit and Computer Keyboard as the scene setter. Once that mental model clicks, the comparison stops being abstract and starts feeling physical.
