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.
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 Egg as the reference unit and Toothbrush as the scene setter. Once that mental model clicks, the comparison stops being abstract and starts feeling physical.
