Here's from shortest to tallest.

I get this question a lot! Have I not said their heights? Maybe not, I can't remember.

Fear: 4ft tall.

Lockheart: 5ft2 / 5ft4 in heels.

Cupid: 5ft3

Coby: 5ft5 / 5ft9 in a half with tail.

Hallow: 5ft7 /6ft in beast form.

Asher: 6ft5 / 7ft in wolf form.

Yeah they're pretty short. Except Ash.

Others: besides the six.

Romeo: 5ft5

Amour: 5ft tall.

Jasper: unknown. But when he was alive he was 6ft in a half.

Hope this helps! Their heights may change as they get updated~!
