Steam assets
Store capsules, library artwork, logos, and screenshots each have different jobs. A strong asset pass keeps the title readable, protects the main subject from awkward crops, and avoids putting marketing text where Steam expects clean game artwork.
Guide breakdown
The common Steam store capsule set includes Header Capsule at 920 x 430, Small Capsule at 462 x 174, Main Capsule at 1232 x 706, and Vertical Capsule at 748 x 896. These dimensions create very different crops, so the logo and main character should be checked in each output instead of relying on one resized file.
Steam library assets include a Library Capsule at 600 x 900, a Library Header at 920 x 430, a Library Hero at 3840 x 1240, and a transparent Library Logo. The Library Hero is especially easy to get wrong because it should contain artwork only, with no text, while the logo is handled as a separate transparent image.
Steam screenshots should show what the game is like to play. Do not use key art, concept art, award graphics, or written marketing copy in the screenshot set. Use real gameplay images and check that they work at a 16:9 aspect ratio.
Before uploading, confirm that every image has the right dimensions, the logo is readable, the key subject is not cropped awkwardly, the Library Hero has no text, and screenshots are actual gameplay. The goal is to prevent obvious review and conversion problems before players ever see the page.

Game marketing gets messy when everything is treated like one giant task. A checklist forces the work into the right order: store page first, tracking next, audience building after that, then bigger beats like creators, demos, and festivals.
Reddit ads can work for games, but only when the targeting, creative, and landing path fit Reddit's context. Broad campaigns with generic creative burn budget quickly.
You do not know a capsule is working because you or your friends like it. You know because the right people click it at a better rate and the page still converts after they arrive.
Use cases
Stop guessing who to contact. Start with your game's genre and instantly find creators already making content in your niche so you can build a real outreach list for your launch.
Skip generic creator lists and random YouTube searches. Start with your game's Steam tags and instantly find creators already covering similar games so you can build a list you can actually use.

FAQ
Common Steam capsule image sizes include 920 x 430 for Header Capsule, 462 x 174 for Small Capsule, 1232 x 706 for Main Capsule, and 748 x 896 for Vertical Capsule. Check current Steamworks docs before final upload.
No. Each capsule has a different aspect ratio, so one resized image can cut off the subject or make the logo unreadable. Crop and review each Steam capsule image separately.
Steam screenshots should show real gameplay. Avoid key art, concept art, awards, marketing copy, and written descriptions in the screenshot section.
