Magnitudle

Magnitudle is the official home of Size It Up, a free daily visual size-estimation game, along with a set of other estimation puzzles. It is built for people who enjoy testing their intuition: instead of trivia recall, each game asks you to commit to a guess and then shows how close you came.

Key Features

• Size It Up: The original daily visual size-estimation game. Each round places a resizable red silhouette beside a blue reference silhouette; you resize the target until the comparison looks true to life, lock in your answer, and see the true size revealed.
• Scoring out of 500: A standard daily Size It Up game has five comparisons, each worth up to 100 points. An estimate within 6% of the target earns the full 100.
• Multiple themes: Play standard Size It Up for real-world scale, plus Pop Culture for fictional scale and Geography for geographic scale.
• Other ways to play: The Weekly 1K (ten rounds on one weekly theme), Weigh It Up for balancing real-world weight, the Daily Question for a single numerical estimate, Survival Mode for fast estimation, and a Weekly Archive for replaying past puzzles.
• Streaks and personal bests: The site tracks an overall streak and personal best across games.

Typical Use Cases

• Daily warm-up: Open a fresh Size It Up puzzle, work through five comparisons, and finish with a score out of 500 to compare against your personal best.
• Practicing estimation: Use the archive of previous standard, Pop Culture, and Geography puzzles to sharpen your sense of scale between daily releases.
• Quick single-guess challenge: Answer the Daily Question when you want a short numerical reasoning break rather than a full five-round game.

How It Works

1. Each round presents a blue reference silhouette and a red, resizable silhouette.
2. Resize the red silhouette to match its scale relative to the reference.
3. Lock in your answer and watch the true size be revealed.
4. Earn up to 100 points per round, with a maximum of 500 for a standard daily game.

Who It's For

Magnitudle suits puzzle players, trivia fans, and anyone curious about how well their intuition maps to real-world scale. No specialist knowledge is required — just reasoning and the nerve to commit to a guess. Daily puzzles become available at midnight in your game timezone, and Survival is a weekly challenge starting each Wednesday.

Magnitudle is a free, browser-based way to test and improve your sense of scale, best suited to players who enjoy a quick daily estimation challenge.
