J.R.- They are only 1-3 inches apart from each other. The height difference is probably because of their shoe heel heights.
Anyone have any idea how tall Kendall is now? Many publications say she is 5'10", but I'm guessing she's more like 6', and there is a good chance she may still be growing. In her early 2012 pics she seems like 2-3 inches taller than her 5'9" sister Kylie but in later pics (August-December) she appears to be anywhere from 3-5 inches taller. In this photo she looks to be pulling away from Kylie who is almost 5'10" herself. Would be interesting if Kendall ended up being taller than her dad, Bruce. Anyone have any knowledge of how tall Kendall is now?
