We see pictures of whales, towers, spacecraft, bridges, and planets every day. The pictures teach us what those things look like, but almost always remove the relationship between them. Each subject is cropped to fit the same rectangle. Size It Up Daily puts the missing scale back.
What this site makes
The core product is an original browser-based visual estimation game. Every daily challenge contains five comparisons drawn from space, animals, landmarks, and everyday objects. Players resize a target beside a fixed reference, commit to the proportion, and then see the true outline with a short fact.
The game is accompanied by practical guides and transparent measurement notes. The guides explain how proportional thinking works. The source notes identify the axis and convention used for the rounds. Together, they turn a two-minute puzzle into knowledge a player can reuse.
Our editorial principles
- Useful before impressive. The game should load quickly, explain itself, and work without an account.
- Plain about uncertainty. Animals vary, manufactured models differ, and landmarks have multiple valid measurement conventions. We describe representative values as representative.
- Sources you can inspect. The round library favors space agencies, public institutions, governing bodies, manufacturers, and landmark operators.
- Privacy by restraint. Daily progress and personal scores remain in local browser storage. The current game does not require a profile, location, or tracking account.
- Independent identity. This project uses its own interface, scoring model, round library, educational writing, and code.
Independence and naming
“Size it up” is a common English phrase and an intuitive description of a size-comparison challenge. Size It Up Daily is an independent project. It is not the official Magnitudle game, is not endorsed by Magnitudle, and does not copy Magnitudle’s assets or account systems. If you are looking for the original Magnitudle mode discussed online, visit the developer’s site directly.
How rounds are maintained
Each object record contains a name, one measurement axis, a value converted to metres, a visual shape, and a source group. Each comparison adds a concise fact that explains the relationship. Before a round is retained, its ratio must fit the interaction range and its wording must make the measurement convention understandable.
Corrections are welcome, especially when an institution updates a published dimension or when a clearer primary source becomes available. Include the round names, the competing values, and a public source so the record can be reviewed consistently.
Where to begin
If this is your first visit, play today’s five rounds. If the first result surprises you, that is the point. Read the note, keep one comparison, and try another. For a more deliberate approach, use the visual size estimation guide before opening practice mode.
