YouTube recommends 1280×720 for custom thumbnails. This is also the size displayed in search results and suggested video panels.
Tips for YouTube Thumbnail Images
YouTube thumbnails should be under 2 MB. Use JPG at quality 85–90 for the best balance. Make text large and readable — most viewers see thumbnails at small sizes.
