You may notice that as you are growing and developing, your body shape is naturally becoming curvier. Your hips actually widen during this time to prepare to carry a baby in the future. Hereditary (the genes you get from your parents) also has a lot to do with what your body shape will be.

Why did my hips get wider?

Pass it on: People's hips get wider as they get older not just because of fat, but because their pelvic bones actually grow wider.

What age do women's hips widen?

With the onset of puberty, the male pelvis remains on the same developmental trajectory, while the female pelvis develops in an entirely new direction, becoming wider and reaching its full width around the age of 25-30 years.
