How to finish a thumbnail: generate the image with one prompt below, then add 3–5 big bold words on top in your editing app (Canva, CapCut or Photoshop). Keep the text short — thumbnails are read at small size on phones.

Tips for Higher Click-Through Rate
- One face, one emotion: thumbnails with a single clear expression outperform busy group shots at small size.
- 3–5 words only: if viewers cannot read your thumbnail text in one second on a phone, it is too long.
- Contrast wins: bright subject on a dark background (or the reverse) is easier to spot in a feed than similar tones.
