How wide? roughly.

How wide? is one of the daily guessing games from roughly., a small site by Hired Hands Games where every game asks for an estimate rather than an exact answer. Here the question is how much ground a city covers, measured as its continuous built-up area rather than its official city limits.

Each day brings five pairs of cities, the same for every player and numbered from 1 January 2026. On Day 299 the first round set Havana against Marseille. The reference city appears as a grey outline at its real size. You drag the second city's outline bigger or smaller over it, or type how many times larger or smaller you think it is. One hint a day tells you the reference city's area and its length at the longest point.

After you lock it in, the game shows both areas, the factor between your guess and the truth, a strip of other guesses with the share you beat, and a short napkin calculation that boxes the city in and estimates how much of the box is built up. The areas come from the European Commission's Global Human Settlement Layer for 2020, in 100 metre cells, so every city is measured by the same rule.

New rounds arrive at midnight UTC. Today's five rounds are free and need no account. One past day a day can be replayed for free, and the paid roughly+ pass ($4.99 once) opens the whole archive and removes ads. You can challenge a friend or play with friends in a room, in English or German, with areas in square kilometres or square miles.
