To find out your Hogwarts house, you can take the Hogwarts Sorting Experience created by J.K. Rowling on the Wizarding World website. There are also several other quizzes available online, such as the one on BuzzFeed, BrainFall, and Heywise. These quizzes will ask you a series of questions to determine which house you belong to based on your personality traits. The four houses of Hogwarts are Gryffindor, Hufflepuff, Ravenclaw, and Slytherin, and each house has its own unique characteristics and values.
