Twitch panel size

Panels are 320 pixels wide. The height is up to you — 300 is the convention, but a schedule panel at 320 × 600 is perfectly valid and often more useful.

The fixed width is the only hard constraint; Twitch scales panels to 320 wide and lets the height follow. That makes the common mistake obvious once you know it: a panel designed at some other width gets scaled and any text in it softens. Design at exactly 320 wide, or at a multiple of it if you want a sharper result on a high-density screen. Panels stack in a column beneath the player and each can carry a link, which is what most people use them for — socials, donation links, a schedule and a gear list.
