Team Capsule Artwork & Game Development Assets

Your capsule art is the handshake between your game and a potential player. A bad one means they never even see your trailer. I have compiled the absolute essentials here: where to check the rules, where to find free assets, and the exact dimensions you need for Steam and Itch.io.

The capsule is the most important asset on your Steam page. It determines if a player stops scrolling or moves on. This list gathers the vital resources you need: official documentation, free asset libraries, and the specific image dimensions for 2026. It also includes links to psychological deep dives on player behavior to help you understand what actually makes people click.

Essential Tools & References

  • SteamDB The ultimate database for tracking Steam traffic, player counts, and how other games handle their updates and assets.
  • SteamCapsule.com A curated gallery of successful Steam capsules. Great for referencing trends, composition, and what catches the eye.
  • Steamworks: Store Graphical Assets Documentation The official manual. Always check this for the latest technical specifications before you start designing.
  • Steamworks: Graphical Asset Rules Crucial reading. Steam has strict rules about text overlays, award logos, and review scores on capsules. Ignoring this can get your page flagged.

Art Resources (Assets, Textures & Stock)

  • Kenney.nl Thousands of high-quality, public domain (CC0) game assets. The gold standard for prototyping and indie friendly assets.
  • OpenGameArt.org A massive community-driven repository of free art, music, and sound effects.
  • Itch.io Free Assets A treasure trove of unique, indie-created assets.
  • Poly Haven Excellent source for free, high-quality 3D textures and HDRIs.
