The 20-year-old model shares a love of Disney movies with all her sisters so decided to match each sibling with the heroine she feels they are most like.
She said: "My sisters and I love Disney movies. We used to watch them all the time when Kylie and I were little. I never really thought about which princess I'm most like, until a friend recently told me that she's such a Mulan, lol.
"It got me thinking about which characters my sisters would be from the movies (and my own personal princess, of course)."
And when it came to 35-year-old Kim, Kendall feels she shares the same "confident, brave and stubborn" qualities as red-haired Ariel.
She explained on her official app: "[She's] headstrong, confident, smart, brave, romantic, stubborn and caring."
Kendall thinks her oldest sister, 37-year-old Kourtney Kardashian is like the "rebellious and intelligent" Princess Jasmine from 'Aladdin'.

And Khloe, 32, has a lot in common with Belle from 'Beauty and the Beast'.
Kendall explained: "[She's] headstrong, confident, smart, brave, romantic, stubborn and caring."
For her "feisty" younger sister, 19-year-old Kylie Jenner, Kendall chose Rapunzel.
She explained: "[She's] feisty, energetic, defiant, courageous, confident [and] kind."
And when it comes to herself, the 'Keeping Up with the Kardashians' star likened herself to Tiana from 'The Princess and the Frog' because she is "smart, determined, hardworking and funny" - as well as "humble".
