I looked around but maybe I just missed it entirely... does anyone know the dimensions for the avatar, or well basically the avatar canvas size of height and width. I hope that makes sense and thank you for the help!

Do you just mean the avatar image size, that's 125x250 You can check the size of any image, by opening the image in a new tab and hovering over the tab of the image

or

Pasting the image into an art programme, eg. MS Paint, and checking the dimensions there In MS Paint it's CTRL+E

I just meant the entire avatar space, think full background. Thank you forgot about that method, I'm getting old.
