A few things you might be wondering
What changes between the different editions?+
Classic compares real-world objects, animals, vehicles, and landmarks. Pop Culture compares fictional characters with familiar real-world references. Geography compares country outlines by their north–south span, not their land area. Every edition has unlimited five-round games, its own best score, and shareable links.
Is this a daily puzzle or an unlimited game?+
Size It Up Unlimited takes inspiration from Magnitudle’s daily puzzle format, with new games available whenever you want. Select New Game for another set of five comparisons. There is no daily limit or countdown, so you can keep practicing your estimation across animals, geography, and pop culture.
How is my score calculated?+
Each round is worth up to 100 points. A perfect match earns 100, and your score falls as your estimate gets further from the true scale. Being twice as large and half as large earn the same score. Your five round scores add up to a maximum of 500.
Can I play the same game as a friend?+
Absolutely. Choose Share game to copy a link containing your game ID. Anyone opening that link gets the same five comparisons and starting sizes. Your guesses are saved only in your own browser, so a friend can play independently.
How do I resize on my phone or with a keyboard?+
On a phone, pull the corner handle, pinch the red silhouette with two fingers, or use the slider under the board. With a keyboard, focus the slider or corner handle and use the arrow keys. The minus and plus buttons also make fine adjustments.
Are these exact real-world measurements?+
We use typical dimensions for animals and everyday objects, and stated dimensions for landmarks. Real examples naturally vary. Each round tells you which measurement to compare and reveals the value after you lock in your guess.
