Thumbnail is a term used by graphic designers and photographers for a small image representation of a larger image, usually intended to make it easier and faster to look at or manage a group of larger images.
Image size and resolution. Your custom thumbnail image should be as large as possible, as the image will also be used as the preview image in the embedded player. We recommend your custom thumbnails: Have a resolution of 1280x720 (with a minimum width of 640 pixels). Be uploaded in image formats such as .JPG, .GIF, .BMP or .PNG. Remain under the 2 MB limit. Try to use a 16:9 aspect ratio as it's the most used in YouTube players and previews.
