The Generational Divide: Age Gaps Between the Kardashian-Jenner Siblings

The siblings are split into two distinct age groups: the four oldest Kardashians (Kourtney, Kim, Khloé, and Rob) and the two youngest Jenners (Kendall and Kylie). The age differences between the siblings are surprisingly large, creating the unique family dynamic that has been a staple of their TV shows.

The biggest age gap is between the oldest and youngest members of the second generation.

• Kourtney and Kim: The oldest sisters are separated by just 18 months, or one year and six months. Their close age makes them natural allies and rivals, a dynamic often explored in their shows.
• Khloé and Rob: Khloé is three years and nine months older than her brother Rob. Rob is the youngest of the original Kardashian siblings.
• The Kardashian-Jenner Gap: There is an eight-year gap between the youngest Kardashian, Rob (age 38), and the oldest Jenner, Kendall (age 30). This large age difference highlights the separate households and life stages of the two groups growing up.
• Kendall and Kylie: The two youngest sisters are the closest in age, with a gap of only one year and nine months. Kendall (30) and Kylie (28) are often seen as the closest pair, having grown up together entirely in the spotlight of the reality show era.

The matriarch, Kris Jenner, celebrated her milestone 70th birthday on November 5, 2025, marking a significant moment for the family.
