Thumbnail Readability Checklist for Creators

A practical checklist for thumbnails that survive small previews and still earn clicks.

• Can the main text be read at a very small size?
• Is there one clear focal subject?
• Does contrast separate text from the background?
• Are there too many competing elements?
• Would the image still make sense with the text removed?

Readability is not only about typography. It is about hierarchy. If every element demands attention, none of them stand out enough for a quick-scroll environment.
