If you don't mind watching a nearly 50 year old video then I can recommend "Powers of Ten" [0], attempting to visualize the different scales on which things are happening in the universe we know of. It is a very short video, just 9 minutes long.
Re "sizes", fwiw, you might like [1]. Something I wrote as conversation prep - loads slowwwwly. Quarks are much smaller than their proton. IIRC, >1000x smaller.
