The original visual game by Magnitudle
How good is your sense of scale?
Size It Up is the original daily visual size-estimation game by Magnitudle. Each round places a target silhouette beside a reference object; resize the target until the comparison looks true to life, then lock in your answer for the reveal.
A standard daily game has five comparisons. Every round can earn up to 100 points, giving you a maximum possible score of 500.
Four simple steps
Each round presents a blue reference silhouette and a red, resizable silhouette.
Resize the red silhouette to match its scale relative to the reference.
Lock in your answer and watch as the true size is revealed.
Earn up to 100 points. An estimate within 6% of the target earns the full 100.
