One of the best parts about Hogwarts Legacy is that it permits students to explore Hogwarts, the surrounding Highlands, and the general mysteries of the wizarding universe in an open-world fashion – but what's the actual size of the map? It can be hard to gauge such a metric in-game, especially with how busy the fifth-year protagonist is throughout their first term at Hogwarts. Between learning new magic, helping out their fellow peers, and of course saving the school from an ever-growing threat, players might not have the time to take in Hogwarts Legacy's actual map size.
