An 800x800 square avatar that still reads at 32 pixels, which is the size most viewers actually see it at.
This becomes a small circle everywhere on YouTube, sometimes as small as 48 pixels. Keep one bold, simple subject centred, and skip fine detail that disappears at that size.
Describe the mark. 800×800, built to still read at 32 pixels.
Describe the avatar and we generate it as an 800x800 square, the size YouTube asks you to upload. What actually matters is how it looks shrunk down: most viewers see your avatar as a circle around 32 pixels wide, next to a comment or a video, so the brief pushes for one bold shape and strong contrast rather than fine detail.
Fine detail, small text or a busy background all disappear at 32 pixels; they only survive on the full-size upload. Runs return one image by default, at 1K resolution, since a bigger file buys nothing an icon this small can show.
Probably not once it's shrunk to a 32-pixel circle. Ask for one bold shape and strong contrast rather than fine detail; that is what survives at that size.
It generates a picture from your description. It is not a photo of you, so a likeness is not reliable. For a face-led avatar, crop a real photo instead.
