Play Size It UpA fresh puzzle is waiting for you.
Size It Up is a daily size-comparison game that asks you to estimate real-world measurements by resizing a purple silhouette to match a green reference object. Each Classic daily challenge contains five comparisons. Points are awarded based on how close your estimate is to the true measurement, and a perfect game scores 500 points.
The site also offers unlimited practice games, a daily archive to replay published challenges, curated topic collections such as Animals, Geography, Universe and Pop Culture, and additional modes like Scale Streak. Every reveal shows the real measurement, the source, and a link to the original reference so you can learn where the data came from.
How to play Size It Up
- Start each round by checking the green reference object which shows a known height, length, diameter or area.
- Resize the purple silhouette until the two objects look proportionally correct relative to the marked dimension.
- Lock in your estimate by tapping Lock in to reveal the true measurement and the points you earned for that round.
- Use the revealed measurement as a reference for the next round; five rounds make one Classic game, and the first completed daily game is recorded in your Daily record.
Tips for Size It Up
- Begin by visualizing how many of the green reference objects would fit along the marked dimension of the purple silhouette before you adjust the slider.
- Make coarse adjustments first to get into the right order of magnitude, then fine-tune with smaller increments or the plus and minus buttons.
- After each reveal, note the actual measurement and use it to calibrate your next guess in the same game, since successive rounds may be related.
- Use Unlimited practice or curated collections to learn common reference sizes for animals, countries, planets, and pop culture figures to improve long-term accuracy.
