Steam capsule image sizes and store asset checklist

Steam assets are not one image resized several ways. Use the right capsule sizes, keep the logo readable, and check screenshots separately before uploading to Steamworks.

Key takeaway

Steam capsule images use multiple aspect ratios, so each crop should be checked separately.

Key takeaway

Screenshots should show gameplay, not key art or marketing graphics.

Key takeaway

Library Hero artwork should stay text-free, with critical content inside the safe area.

Key takeaway

Final uploads should always be checked against current Steamworks documentation.

Steam assets

Prepare each Steam image for the place it actually appears.

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

Know the core store capsule sizes

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.

Check library assets separately

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.

Keep screenshots as gameplay screenshots

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.

Use the checklist before upload

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.

FAQ

What size are Steam capsule images?

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.

Can one Steam capsule image be resized for every placement?

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.

What should Steam screenshots show?

Steam screenshots should show real gameplay. Avoid key art, concept art, awards, marketing copy, and written descriptions in the screenshot section.
