When a girl begins puberty, many physical changes will occur both externally, that you will be able to see, and internally, that you will not be able to see. Externally, an overall growth spurt happens where the girl’s body grows taller and weight increases. Read about the changes a girl will go through during puberty including changes to her:

  • Face
  • Chest
  • Genitals
  • Hips and Legs


Many changes happen to a girl’s face and neck during puberty. The face changes in shape and becomes less round. Rosy cheeks may develop. Pimples may appear anywhere on the face. The girl’s voice will deepen slightly because the voice box increases in size.
