About the Twitch Banner Tool
Your Twitch profile banner (also called offline banner) needs to be 1920x480 pixels for maximum impact. This ultra-wide 4:1 aspect ratio is often tricky to create — our tool applies a smart crop to any image, maximizing your branding presence without black bars or distortion.
