KOURTNEY Kardashian's a pint-sized beauty, while her little sister Kendall Jenner is a striking catwalk model.
So who's the tallest of the five sisters, and where does mum Kris measure up? Here's what we know...
Who's the tallest Kardashian-Jenner sister?
Kendall Jenner: 5ft10
Dad Caitlin is 6ft2, so it's hardly surprising her daughters are tall too.
Kendall, 22, towers over her 'big' sisters - with the exception of Khloe - with her height paving her way for a future in modelling.
Khloe Kardashian: 5ft10
Khloe, who's now a mum-of-one to baby True, matches Kendall at 5ft10.
Her height may explain why the 34-year-old has a thing for basketball players.
Speaking about Khloe and Kim, she previously : "They are 5ft and 5ft2, so I look massive next to them.
"Everyone expects me to be 9ft tall...when they meet me."
Kylie Jenner: 5ft6
Mum-of-one Kylie comes in the middle of the pack - measuring in at 5ft6.
The 21-year-old previously revealed her height in a tweet to a fan.
Fun fact: she's the same height as momager Kris.
Kim Kardashian: 5ft2
Mum-of-three Kim, 37, is hardly ever seen without a pair of sky high stilettos, and there's a reason for that.
She measures in at 5ft2, while hubby Kanye West is also shorter than Khloe and Kendall - at 5ft9.
Kourtney Kardashian: 5ft
