Size It Up 3D

Resize the mystery object and discover how big the world really is. Size It Up 3D is a playful 3D comparison puzzle game set in a colorful museum of scale. Use an object with a known height or length as your reference. Grow or shrink the target until you think its real-world size is right, then lock in your estimate. The reveal shows the true size beside your guess, with a score and up to three stars for your accuracy. Explore 240 fixed challenges across 12 themed exhibitions, featuring 96 objects ranging from everyday items and animals to vehicles, landmarks and giant creations. Clear each exhibit to unlock the next and return to improve your best score. Choose your way to play: Campaign: progress through all 240 challenges, starting with three guided tutorial exhibits. Free Play: practice with a chosen exhibition and difficulty for as long as you like. Daily Challenge: take on five comparisons each day, with no internet connection required. Local Multiplayer: share one controller with 2 to 4 players. Each player guesses before the answers are revealed. Browse your collection, inspect the 3D models and test your sense of proportion with height and length guides. Orthographic viewing keeps both objects on a shared scale as you rotate and zoom the camera. Play with a controller or keyboard and mouse. Adjust sound, graphics quality, input sensitivity, vibration and reduced motion to suit your setup. Progress and best scores are saved locally. All game text is in English. Multiplayer is local pass-and-play; players take turns using the same device and controller.
