How big? roughly.

How big? is one of the daily guessing games from roughly., a small site where every game asks for an estimate rather than an exact answer. Here the question is size: how tall, long or wide is something compared with a thing you already know?

Each day brings five pairs, the same for every player. A pair might be an emperor penguin and a tennis racket, the Willis Tower and the Statue of Unity, or a rhino and a hockey puck. The left shape is the reference and does not change. You drag a handle on the right shape, or use the arrow keys, until you think it has the right size, or you type its height or length in metres, feet or another unit. The view zooms out as needed so both things always fit, and when the target is much bigger, copies of the reference stack up behind it so you can count how many fit.

Your result for each round is a factor, such as 1.3x too big, rather than points, and the day's result combines all five. You also see what share of players got closer. New pairs arrive at midnight UTC. Today's rounds are free and need no account. One past day a day can be played free from the archive, and roughly+ opens every past day for a one-time $4.99. Outside the EU and Switzerland the free game shows Google ads, which roughly+ also removes. You can challenge a friend or open a room to play the same five together. The game runs in English and German and links each object to its Wikipedia article.
