Okay enjoy what I am dubbing as the canon height chart in my fanfic.
We will go from tallest to shortest.
G is the tallest because he is a combination of Gaster and Sans.
Clive(HumanTale) is the next tallest because he is a human so is not as short as the skeletons.
Nightmare is next, mainly because in his gooey state I imagine him taller.
Lust is next because he 'exercises' more...being tall gives him more customers.
Reaper is next (really don't have a good reason why) I just feel he'd have more height to him.
Error is next (don't judge me) but I like tall Error :3
Storyshift Sans is taller than normal Sans (not by much).
Alister(Altertale) is the same height as Storyshift.
Sans (oh look the classic is here) so everyone after him is either same height or shorter.
Pluto(Outertale), Geno, Trainertale, Fresh, Underpray and Dancetale is same height as Sans.
Raven and Red actually share the same height, Raven is smaller than Sans because his wings needed a smaller body
to carry him (I know what you all are thinking).
THEN HOW DID RAVEN CARRY US!
Magic XD
Red is small because of his brother and his universe.
Ink is next (yus I love idea that Ink is small), it's just adorable plus I have a sister who is an artist and she is tiny compared to me.
Dream is next (god look at how far he is from his brother), I dunno why but Dream being small is just ADORABLE!
Blackberry and Blueberry are tied for
"NO WE DON'T!"
...Um...I-I mean *cough
Blackberry is next in height because of his heels (tho I don't really count them but because he is threatening to end my life got no choice).
Finally is Blueberry...yes he is the smallest...
Oh also...if someone could maybe assist me...I've got a...skeleton problem...
*The skeletons will also reply to comments relating to them*
