The correct YouTube thumbnail size
YouTube thumbnails should be 1280x720 pixels (16:9 aspect ratio), with a minimum width of 640px. Files must be under 2MB in JPG, PNG, or GIF.
Resize your image to exactly 1280x720 so YouTube doesn't crop or stretch it unexpectedly.
Make thumbnails that get clicks
Keep faces and text large and centered — thumbnails are often viewed tiny on mobile. High contrast and bright colors stand out in the feed.
After resizing, compress to stay under 2MB while keeping text crisp.
