About Size It Up
Size It Up is a daily estimation puzzle about your sense of scale. Every round puts a green reference you know, such as a person, beside a purple silhouette of something else. You make the purple object bigger or smaller until the two look right together, then lock in. The game shows the correct size in orange beside your guess, with the real measurement, how far off you were, a short fact and a link to the source.
Each round is worth up to 100 points and a game has five rounds, so a perfect score is 500. Scoring is by ratio: a guess twice the real size earns the same as one half the real size, and a guess five times out earns nothing. The daily challenge is the same five comparisons for everyone and resets at midnight UTC. Unlimited mode deals a fresh five whenever you like, Scale Streak keeps going until you miss, and the Geography topic compares the areas of countries. There is no timer.

How to play Size It Up
Resize the purple silhouette until it looks life size next to the green reference, then lock in your guess and see the real measurement.
Look at the green reference and read which dimension is being measured.
Drag the slider, drag the corner handle or press plus and minus to resize the purple silhouette.
Press Lock in my guess when the two look right together.
Read the real measurement and your points, then go on to the next round.
Finish all five rounds to see your score out of 500.
Tips and strategy
- Count how many of the reference would fit along the purple object, then set the size to match.
- Check the label: a bus is measured by length, a giraffe by height.
- For maps, doubling the area only makes the outline about 1.4 times wider.
- Zooming the board never changes your answer, so use Fit to see both shapes.
