Size It Up: Measure the World

How big is a blue whale beside a passenger jet? Size It Up turns real-world dimensions into a visual puzzle you can play every day. Resize the object on the right beside a fixed reference until their proportions look right. Lock in your estimate to reveal the measured sizes, an interesting fact, and a precision score. Five new comparisons make each daily challenge a quick test of your intuition. WHAT YOU CAN DO • Solve a five-round daily scale puzzle and build a streak. • Practice with more comparisons whenever you want. • Explore original illustrated objects, from everyday items and animals to vehicles and landmarks. • See your percentage error and earn a Bullseye with a round score of 95 or more. • Share a spoiler-free text result in one tap, with your score, emoji grid, and daily streak when you have one. • Compare daily scores and weekly point totals on optional online leaderboards. Core puzzles work offline, and no account is required to play. Internet access is needed for the leaderboard. The mobile app may show ads. Look closer. Guess the scale. Measure the world.
