Princess Skystar

So, I got this age list at https://scifi.stackexchange.com/questions/6699/pony-ages-in-my-little-pony-friendship-is-magic (all information is rightfully theirs.) Fluttershy is the oldest at the age of 20 (one year older than Pinky and enrolled two years prior to RD so she's much larger). Apple Jack and Pinkie Pie are 19 (AJ and PP never attended school, at least as shown, but AJ does mention getting her cutie mark last). Rainbow Dash and Rarity are 18 (RD and Rarity both were enrolled at the same year. That's why they are the same size). Twilight Sparkle is the youngest at 17 years old (She is Princess Celestia's protege, but she was sent to Ponyville to CONTINUE her studies, therefore she hasn't graduated yet. She is also scared of being held back/sent back grades, implying that she is still in school). So, with these ages, My guess would be: Fluttershy is around 5'11" (Small and quiet for her age) Applejack is around 5'10" (Big enough to move huge crates of apples, right?) Pinkie Pie is around 5'11" Rainbow Dash is around 5'8" (has to be tall enough to be sports captain) Rarity is around 5'6" (Small and dainty, am I right?) Twilight is round 4'8" Of course, these are in human heights.
