How Howbigle plays that idea
Howbigle is a free daily size comparison game for a US audience. It runs in the browser. Each day has five rounds. A reference adult human, always 5 ft 7 in (1.70 m) tall, stands beside an original silhouette of the day’s object. You scale the silhouette, lock in, and receive up to 100 points. Within 6% is a perfect 100. The score then declines on a smooth logarithmic curve, which is a fair way to treat errors that span orders of magnitude. Being twice as big and twice as small are the same kind of mistake; both score 36. Five rounds make a total out of 500.
After you lock in, the game overlays your guess on the true silhouette, lists the published size in feet and in meters, tells you how many adult humans that equals, and cites a source. That last point is deliberate. A “typical adult male African bush elephant, 3.3 m at the shoulder” is a different claim from a record animal, and a tower height that includes an antenna is a different claim from a roof height.
Independence, and other games in the genre
Size comparison games have existed in books, museum exhibits, and websites for a long time. In the daily-browser-game wave, Size It Up is a well-known title in this genre. Howbigle is not that game, is not affiliated with it, and does not use its assets or its question bank. If you came here after searching for a size comparison game, you can play Howbigle on its own terms, and you can also seek out the official pages of any other game you already enjoy.
For a direct comparison of intent, we published games like Size It Up and a Size It Up alternative. To jump straight into a round, go to the Howbigle daily game, or open unlimited practice.
A few things you might wonder
What is a size comparison game?
It is a game that asks you to judge how large one object is relative to another, then scores how close your judgment was. Howbigle does this visually, with a slider and a published measurement for each object.
Why use a reference object?
A length in feet or meters is hard to feel on its own. Standing a blue whale next to a person, at a claimed scale, makes the ratio visible. Howbigle’s regular reference is an adult human 5 ft 7 in tall.
Are the sizes exact?
Some are, such as a 50-meter competition pool or a 100-yard football field. Many animal sizes are typical adult values with a stated range. Every Howbigle reveal includes a note and a source so you can see which kind you just played.
