First size: Ok, not bad.
Second size: Yeah, watching together.
Third size: Just hugging and bopping, ok?
Fourth size: L E N N Y F A C E
Fifth size: Uhh…who’s pony is that?
Around 120-150 CM a ride-able size (because i want to ride them), also honestly when artist just draw them smaller than 120cm heck even someone just mention about their headcanon like that, it can piss me off sometimes, because they aren’t really have similar size as the real one. I know it’s a cartoon and sometimes animator can be fuck up for scaling like >>553033 and >>867775. And everyday stuff can be exaggerated larger than the real one to match with their head size. But they still a pony and they should they have a similar size with the real one at least by my headcanon. Also if i have the last one i can finally put my name in Guinness World Records.
According to my headcanon, they’re about 100 to 120 centimeters (measured to the top of their head when in a neutral posture) on average, or about the same size as a Great Dane, or an actual real-life miniature horse. Some artists draw them at about the size of the average house cat, which always ticks me off for some reason. Mostly because I dislike cats, but also because I find it absurd that these creatures would be depicted as that small and powerless next to a human, after the feats they’ve demonstrated themselves to be capable of. Bigger is better. More to snuggle that way.
There is, however, a downside to making them around 1.0 to 1.5 meters tall, and it’s that their head size relative to a human’s becomes utterly freakish. A giant balloon with saucepans for eyes.
