How to play Size It Up
- Read the black-blue reference. It is already at true scale, with its real measurement labelled.
- Slide on the board or use the slider until the cream silhouette looks right. The ruler is linear, and the midpoint number is marked.
- Lock in. The true size lands in red. Later you see where you sit among everyone who finished today.
Size It Up scoring
Score is the ratio between your guess and the true size, not a raw metre gap. That is why a whale drawn twice too long and twice too short both score 45.

Size It Up is linear
Twice as wide means twice the real length. You size it up by eye. The midpoint of the ruler is labelled, and the slider is not logarithmic.
