How many Weasley children are there?

The story behind the answer

Arthur and Molly Weasley have seven children: Bill, Charlie, Percy, Fred, George, Ron, and Ginny—six boys and one girl. Fred and George are the famous prankster twins, and Ginny is the youngest and only daughter.

Seven is a magically significant number in the series—seven years at Hogwarts, seven Horcruxes, and seven players on a Quidditch team. To remember, think: the Weasleys could field a full Quidditch team. Or recall the family flow: two trailblazers (Bill the curse-breaker, Charlie the dragon-handler), the rule-stickler Percy, the twin jokers, Ron the loyal friend, and Ginny the sharpshooting Chaser.
