About SizeItUp
How big is a blue whale? How tall is a rocket? Put your sense of scale to the test in Size It Up! Explore 70 objects across six categories, discover their real-world sizes, and build your collection in this relaxing guessing game.
How to play SizeItUp
Compare the target object with the reference shown.
Drag the gold corner handles or use the slider to resize it.
Click “That’s the size!” to submit your guess.
The closer you are to the real size, the more points you earn.

Compare proportions before fine-tuning
Start with a rough relationship to the reference, then refine it using the slider or gold corner handles. Read which measurement the round is asking you to estimate.
Learn from the reveal
The result gives your estimate context. Notice whether you were a little off or on a completely different scale, then use that comparison when you meet a similar object.
