If you have Photoshop you can edit this image also as we provide PSD file with all assets/icons for you to change.)
Twitch recommends 1200x480px size but we also provide 1920x480px as default cover. 1920x480px size look better on the bigger resolution and visually is more clear and nicer but you are free to use what ever you think suits you best.
