Keeping track of the Kardashian-Jenner family tree can feel like tracking a moving target. Between multiple generations, blended family lines, and decades of reality television history, ages and birth order get confusing fast. If you're trying to figure out exactly how old each family member is right now, you're in the right place.
The core Kardashian-Jenner family spans from momager Kris Jenner, born in 1955, down to a large generation of grandchildren born into the spotlight. Chronologically, the famous siblings break down across two distinct eras of the family: Kourtney, Kim, Khloé, and Rob from Kris's marriage to Robert Kardashian, followed by Kendall and Kylie from her marriage to Caitlyn Jenner.
The Matriarch and the Core Siblings
Understanding the family ages starts at the top with Kris Jenner, who anchors the entire enterprise.
- Kris Jenner: Born November 5, 1955. As the executive producer and manager behind the family's multi-media empire, she turned family milestones into global pop culture events.
- Kourtney Kardashian: Born April 18, 1979. As the eldest of the siblings, Kourtney established her lifestyle brand Poosh and frequently documents her blended family life with husband Travis Barker.
- Kim Kardashian: Born October 21, 1980. Kim launched the family's mainstream fame with the debut of Keeping Up with the Kardashians and has since expanded into shapewear with SKIMS and legal reform advocacy.
- Khloé Kardashian: Born June 27, 1984. Khloé has anchored several reality spin-offs, co-founded the denim brand Good American, and manages her career alongside raising her children.
- Rob Kardashian: Born March 17, 1987. The youngest of the original four siblings, Rob has largely stepped back from the primary public eye compared to his sisters, focusing on fatherhood and private business ventures.
The Jenner Sisters
Born from Kris's marriage to Olympic gold medalist Caitlyn Jenner (formerly Bruce Jenner), the two youngest siblings grew up entirely in front of television cameras.
- Kendall Jenner: Born November 3, 1995. Kendall carved out a distinct path from her siblings by pursuing a high-fashion modeling career, walking runways globally, and launching 818 Tequila.
- Kylie Jenner: Born August 10, 1997. Kylie leveraged her massive social media presence to build Kylie Cosmetics, turning digital influence into a massive beauty enterprise.
The Grandchildren Timeline
The next generation adds another layer of complexity to the family timeline. The grandchildren span teenagers to toddlers, reflecting the wide age gaps between the older and younger sibling sets.

Why the Kardashian Timeline Matters in Pop Culture
Tracking the ages of this family reveals how long reality television has tracked modern celebrity culture. When Keeping Up with the Kardashians premiered on E! Online back in 2007, Kim was in her twenties, Kendall and Kylie were elementary school children, and the current crop of grandchildren didn't exist yet.
Watching the family transition from Hollywood partygoers to multi-industry founders provides a clear roadmap of how digital media transformed personal branding. While older profiles often freeze the family in their mid-20s or 30s, the current reality shows a matriarch in her seventies, siblings navigating middle age, and a robust teenage generation stepping into public view.
