An original daily comparison
Each Howbigle day gives you five objects drawn from a public-fact bank: animals, buildings, vehicles, and geography. The silhouettes are original artwork made for this site. The sizes come from published measurements, with a source note after you lock in.
Howbigle is not affiliated with Size It Up, Magnitudle, GriddleLink Games, or any other size-guessing game. It is an independent project with its own questions, scoring, and visual style.
A few things you might wonder
Is Howbigle the same as Size It Up?
No. Howbigle is an independent daily size-estimation game with original silhouettes, its own scoring, and a public-fact item bank. It is not affiliated with Size It Up, Magnitudle, or GriddleLink Games.
How is my score calculated?
A guess within 6% of the published size scores 100. Beyond that, the score falls smoothly with the absolute log-ratio of your guess to the true size, so doubling and halving are equal mistakes. A guess twice the true size scores 36; around five times the true size scores 8. Five daily rounds make a total out of 500.
When does the daily puzzle change?
At midnight in the eastern United States (America/New_York), including daylight-saving changes. Unlimited practice is available at any time and does not change your daily score or streak.
Where do the sizes come from?
From public facts such as encyclopedia entries and published specifications. Each reveal includes a short note and a source link. Typical values and ranges are labeled as such. The figures are for a casual game, not for technical work.
Do I need an account?
No. Your daily scores and streak are saved in your browser on this device. Clearing the site’s data will reset them.
