Khloe is the tallest of the sisters at a towering 5ft10in with Kim falling in the middle at 5ft3in, while Kourtney is the shortest of the trio at 5ft1in.
There have been multiple images uploaded to social media by the Kardashian sisters themselves that show the variation in their heights, as well as hundreds of photos taken of the trio at public events.
The promotional images appears to be yet another case of photoshopping gone wrong with fans speculating that Kim and Kourtney had their legs elongated while Khloe's had hers shortened digitally. Fans also joked that the Photoshopped height is Kourtney's dream height.
This isn't the first time the girls have come under fire for dodgy Photoshopping. Kim has constantly been accused of Photoshopping her Instagram images while Khloe was once slammed for altering her leg in a photo last year.
