So, I import my animations into Scratch, and I was wondering, how big is the screen?

It's 480 pixels wide and 360 pixels tall.

Thanks!

I was also wondering, how big is the studio thumbnail size? In pixels please.

170 by 100.

See https://scratch.mit.edu/discuss/post/4268940
I recommend making the thumbnail 17:10 but make sure it looks good if the aspect ratio is 20:13 too.

Edit: maybe 340x200, that should look good everywhere.
