The YouTube thumbnail rules
YouTube recommends 1280×720 pixels, a 16:9 frame, with a width of at least 640 pixels. Thumbnails display small in search and on phones, so a sharp 1280×720 image with big, readable text works best.
YouTube also caps thumbnail files at 2 MB. If your export is bigger, lower the quality slider: most thumbnails look the same at 80 to 85.
Making the thumbnail from your own video? Extract a sharp frame first with the frame tool, then resize it here.

What if my image isn't 16:9?
