How to make a steam library hero
- Type a short title. The text resizes itself to fit the 3840 × 1240 shape.
- Choose a background and text color. Pick Round photo on the right to keep the left side free.
- Turn on Show safe zone guide to check that nothing important sits too close to the edges.
- Keep the format on JPG, then click Download banner. A short video ad plays first, then your file downloads.
- Upload it in Steamworks under Store Presence, then Graphical Assets.
Design tips for a 3840×1240 image
- Use big, high-contrast text. A wide image is often shown small, and thin letters become hard to read.
- Keep the main message in the middle third in case an app crops the sides.
- Need a different size? Use the Banner size menu above to switch to another preset or type your own width and height.
