Why this game exists
We see animals and objects on screens every day, usually without a reliable sense of scale. Size It Up turns that uncertainty into a short comparison game. You look at a reference, make an estimate, and see how close you came.
This is an independent size-estimation game. It is not affiliated with other games or sites using similar language.
How a puzzle is made
Each object has a selected measurement, a named dimension, a variant or range note, and a link to the source used for the answer. The same record feeds the puzzle result and the public measurement list. Illustrations are made for this site and are used to make comparison pleasant; the written value remains the scoring reference.
Choose your pace
Unlimited practice lets you keep going through the full comparison pool. If you notice a measurement or artwork problem, visit Contact and Corrections.
Operator identity and a monitored contact address will be added before public launch. The live site should identify its operator here.
