Size Comparison Game

Is a blue whale longer than a jet? Size Comparison Game puts things on one scale, gives you a known reference, and lets you drag the other object to the size you believe.

Themed sets you can pick

Animals
Buildings and landmarks
Space and planets
Dinosaurs
Everyday objects and vehicles

Why your eye gets it wrong

We judge size by things we see often. A giraffe feels huge because we compare it with people, but next to a building it shrinks. Before you lock in, ask how the object compares with the reference, not with your memory of it.
