How Big? Guess the Size

Size it up game

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

A gorilla next to a person. A shark next to a car. Resize the silhouette until it looks right, lock it in, and see how close you really were. How big is a moose next to a London bus? A T. rex next to a giraffe? You probably think you know. How Big? puts two silhouettes on the same ground line. One is fixed. You resize the other until it looks right — drag, pinch, zoom — then lock it in and watch the real size grow into place next to your guess. • 865 levels with 163 things, from a chicken egg to the Burj Khalifa • Every size checked against real measurements • Up to 100 points and 3 stars per level — replay any level to beat your best • One-handed controls, light and dark mode, works on iPhone and iPad • Share a level and dare your friends to beat your score — without spoiling the answer • Plays offline Ads appear between every second level. A one-time purchase removes them for good, and it restores on all your devices.
