We have no canonical answer, but I see them as shoulder height to Shee, and the Shee as slightly taller than humans so yeah... they would be pretty scary to behold lol
That does sound rather scary. XD
I think most people imagine them human-sized, because they do match the size of the furniture and doors, but I don't know, I just can't imagine them to be so large with their proportions. Their neck would just snap.
This is what's pretty much thrown me out. I've been trying to work out if the furniture and doors were made specifically for Norns or if the Norns are just... big.
Personally, I imagine the shee about the size of tall, slender humans and norns, ettins and grendels are maybe waist-height (hair not included).
I think that'd bring them to a good balance between being cute and being good their canonical purposes of carrying around tablets of tea and biscuits (norns) and clearing out debris and old handheld tools (ettins).
Just imagine this big-eyed, child-sized creature offering you a beverage while it babbles in it's silly language!
That sounds like a good middle-ground, as does SpaceShipRat's 'Norns - doorknob height/Grendels - chimp-sized' suggestion. They do sound a bit closer to what I had in mind.
When I get around to doing these doodles (whenever that will be), I'll keep these suggestions in mind. Thank you all for your help.
