SO this subject came up in a conversation and I decided to roll with it so let’s go from the start WOOT!

All of the heights are based off this ratio of 42pix : 80in since it’s a solid source to go off of :D

He’s so short lol xD

Her hair has a foot of height on its own OwO

Giant Goat Dad

Still pretty big Goat Mom

DONE! :D
The only other height chart I’ve seen was one what went off an assumption of Frisk’s age and the average height of a child said age :/
Doors are good to go off of, so here ya go :D 

*Edit* Saw someone bring it up, Chara is 30pix making them the same height as Sans and 2in taller than Frisk :3 (1.45m)

Another Edit with Muffet :D

*A HUGE EDIT* 
@muffetsofficial asked me to add some other characters to this
HERE WE GO!!!!

But then I though, WHY STOP THERE???
KEEP GOING!!!!!!!

AHHHHHHHHHHHHHHHHHHHHHHH

TO THE CHALLENGE ANON
HERE YA GO DAMNIT

First order of business on the table  

Now that that’s out of the way
