J.K. Rowling, the author of the beloved Harry Potter series, has long been known for her creativity and ingenuity when it comes to her stories. One of the most iconic elements of the series is the concealed platform 9 3/4, which is the magical platform that transports young witches and wizards to Hogwarts School of Witchcraft and Wizardry. But why did Rowling choose the number 9 3/4?

In an interview with The Leaky Cauldron, Rowling revealed her thoughts on the matter. She said that she wanted the platform to be a fraction, and thus had to choose a number between the Muggle platforms. She chose 9 3/4 because it was “a fraction that was discreet enough not to be noticed by Muggles, but daring enough to attract the attention of curious witches and wizards.”

In addition, Rowling also revealed that the number 9 3/4 has a special significance for her. She said that it was the age she was when she first had the idea for the Harry Potter series. She said that the idea “came to me fully formed, and I knew immediately that it was the key to unlocking the entire story.”

Thus, it seems that Rowling chose the number 9 3/4 for a combination of practical and personal reasons. It was a fraction that was discreet enough to go unnoticed by Muggles, but daring enough to attract the attention of curious witches and wizards. It was also a number that held special significance for Rowling, as it was the age she was when she first had the idea for the Harry Potter series.
