What size should your YouTube thumbnail be?
The correct YouTube thumbnail size is 1280 x 720 pixels, using a 16:9 aspect ratio — the same ratio YouTube uses for the video player itself. YouTube's minimum accepted width is 640px, but 1280x720 is the recommended size for the sharpest, highest-quality result across desktop, mobile, and TV.
If you're uploading an image that doesn't match this thumbnail size, you'll need to resize it before it'll display properly. If you don't, YouTube will crop or letterbox it, which can cut off text or faces. With Glif, there's no separate YouTube thumbnail resizer step: every thumbnail you generate is automatically output at the correct 1280x720 size and 16:9 ratio, ready to upload directly. If you have a thumbnail already that you'd like to resize, just upload it and ask Glif.
