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. Backpack and Step Ladder also separate through footprint, thickness, or diameter once you stop treating them like flat outlines.
Shared category can hide the gap
Because both objects live in the same general category, people tend to sort them into the same mental bucket and smooth over the real difference. The comparison matters precisely because they feel related while occupying meaningfully different amounts of space.
Key insight
Treat Backpack as the reference unit and Step Ladder as the scene setter. Once that mental model clicks, the comparison stops being abstract and starts feeling physical.
