Steam Capsule Sizes and Store Graphics: 2026 Reference

2026-08-22

Last verified: 2026-09-26, against Valve's Steamworks documentation (sources at the bottom).

A Steam page needs more artwork than most developers expect: four store capsules, at least five screenshots, four library images, and two icons, and each one is used in a different place with its own rules about text. This is a reference for the sizes Steam currently accepts, which ones are required, where each is shown, and what Valve will reject. Valve's overview page carries a banner that since August 2024 Steam accepts larger asset sizes and no longer accepts the old dimensions, so any older guide or template you find may be out of date.

The short answer

The four required store capsules are Header 920×430, Small 462×174, Main 1232×706, and Vertical 748×896.
Screenshots: at least five, minimum 1920×1080, 16:9, gameplay only. The minimum is not 1280×720.
Library assets (capsule 600×900, header 920×430, hero 3840×1240, logo) and two icons are also required, and they only show up once your store page is published.
Text on capsules is limited to your game's name and an official subtitle. No review scores, awards, discount text, or promotion of other products.
The 3840×1240 image is the Library Hero, not a store capsule, and it must contain no text at all.

Store assets

Asset	Size (px)	Required?	Where it's used
Header Capsule	920×430	Required	Top of the store page, "Recommended For You", Big Picture browsing, Daily Deals. Smaller versions are generated automatically.
Small Capsule	462×174	Required	List views such as search, top sellers, and new releases. Steam auto-generates 120×45 and 184×69 versions.
Main Capsule	1232×706	Required	The Main Capsule carousel at the top of the Steam home page; also used in wishlist emails.
Vertical Capsule	748×896	Required	Top of the front page during seasonal sales and on other sale pages.
Screenshots	1920×1080 minimum, 16:9	Required (at least 5)	Store page gallery. Gameplay only; mark at least 4 as suitable for all ages.
Page Background	1438×810	Optional	Ambient background. If you skip it, Steam builds one from your last screenshot.
Bundle Header	707×232	Only for bundles	Bundle pages.

Valve's design guidance for these is worth quoting in spirit: use the same key art you'd put on a retail box or in marketing, make sure it tells the customer something important right away, keep the logo easy to read, and don't add quotes or strings of text beyond the title. The Small Capsule is the one place you can deviate, since its art doesn't have to match the other capsules. Valve says the logo should nearly fill it. At 462×174, next to a dozen other games, a big readable logo beats detailed illustration.

Library, icon, and event assets

Asset	Size (px) and format	Required?	Notes
Library Capsule	600×900	Required	Library overview and collections. A 300×450 version is auto-generated. Logo (and subtitle) only.
Library Header	920×430	Required per the overview	Recent Games and similar spots. Valve's library page says it falls back to the Header Capsule if not set, but upload one anyway.
Library Hero	3840×1240 .png	Required	Top of the library details page. No text. Keep key art inside the centered 860×380 safe area; 1920×620 is auto-generated.
Library Logo	1280 px wide and/or 720 px tall, transparent .png	Required	Placed over the hero at bottom-left, top-center, middle-center, or bottom-center. Logotype only, plus an optional logomark.
Shortcut Icon	256×256 or 512×512 .ico/.png	Required	Also submit an .icns "Mac Icon" for macOS shortcuts.
App Icon	184×184 .jpg	Required	Library list, chat favorites, notifications.
Event Cover	800×450	Required for events	Community events.
Event Header	1920×622	Suggested	Check Valve's template for clipping.

The most common mix-up is the hero. Some older guides call 3840×1240 a "hero capsule" for promotional banners. It isn't. It's the Library Hero: the background of the library details page. Because it has no text, your title arrives via the separate transparent Library Logo laid on top, so compose the hero as pure artwork with the important part in the middle 860×380. Valve's docs still have a "#hero_capsule" anchor on the standard assets page, but the content under it is the 748×896 Vertical Capsule.

The Steamworks pages I checked don't state a maximum file size for capsules, and they only specify file formats for the Library Hero (.png), Library Logo (.png), App Icon (.jpg), and the two shortcut icons. For the rest, export high-quality PNG or JPG and let the uploader tell you if it objects.

The August 2024 size change

On August 6, 2024, Valve announced that sizes for the small, header, main, and vertical capsules, and the library header, were doubled. Old sizes were accepted until November 1, 2024, and are no longer accepted now. Existing uploads from before the change keep working; you don't have to re-upload them. Valve says only "2x" and doesn't list the old numbers, so if you come across a guide whose sizes are exactly half of the ones in this article, it's describing the pre-2024 spec. No new asset types were added in that change; the existing ones were simply enlarged.

What you can and can't put on a capsule

Valve's asset rules (introduced in 2022) apply to the base capsules and are the most common reason people get sent back:

Allowed: game artwork, the game's name, and an official subtitle.
Not allowed on base capsules: review scores, awards, discount text, promotion of other products (including your own sequel), and miscellaneous text.
Library Capsule: logo (plus subtitle) only. Library Hero: no words at all. Library Logo: logotype only.
All capsules: the logo or name must be readable, dimensions must be exact, and artwork must be PG-13.

The stated consequence in Valve's rules is limited visibility in the Steam store and being ineligible for featuring in official Steam sales and events. Awards and review scores have their own dedicated place on the store page instead.

When you do need to announce something, use an Artwork Override. It's the only sanctioned way to put update or event text on your capsules. An override runs for at most one month, and its text must be localized into at least the languages your game supports. It's meant for a major update, seasonal event, battle pass, DLC, or similar new content, and it can't copy another product's assets. Valve's tip: start the override about five minutes before a discount begins so wishlist emails pick it up.

Step-by-step workflow

Decide the key art and logo. Use your retail-box or marketing art as the base.
Get Valve's templates. A template link is on the Steamworks Standard Assets page. Build the four store capsules at the current sizes first, then the library capsule, header, hero, logo, and icons.
Capture five or more screenshots at 1920×1080 or larger and flag at least four as suitable for all ages. Capture tips are in How to Capture Great Game Screenshots.
Upload in Edit Store Page, on the Graphical Assets tab. For the Library Logo, use the preview tool after upload to choose its position.
Preview with "Preview changes in store" (Store Beta Mode). Note that the hero, logo, and other library items only render once the store page is published, so don't panic if they're missing in a beta preview.
Submit and go Coming Soon. Mark the page ready for review (Valve asks for seven business days of lead time and review takes 3 to 5 business days), then post it as Coming Soon at least two weeks before release.
Update later with Artwork Overrides instead of editing the base capsules.

Documented rejection reasons and mistakes

Mistake	What Valve says
No readable title or logo on a capsule	Capsules must have a readable product title or logo; this is checked in review and in the asset rules.
Wrong dimensions	Dimensions must be accurate. Old pre-2024 sizes are no longer accepted for new uploads.
Screenshots that aren't gameplay	Concept art, pre-rendered stills, awards, marketing copy, and written descriptions get flagged. Menus are okay only if they're unique.
Non-PG-13 capsule art	Capsule artwork must be PG-13.
Scores, awards, discounts, or sequel ads on the capsule	Not allowed on base capsules; limits visibility and blocks featuring in official sales and events.
Showing content not in the launch build	Review requires removing content or features that are incomplete or planned.
Links or Steam-UI lookalikes	No links to other sites in descriptions or graphical assets (including QR codes and implied URLs), and no images that mimic Steam's UI such as fake wishlist or buy buttons, other capsules, or prices.
Text on the Library Hero	Not allowed; zero words. Put your title in the Library Logo.

Mobile stores vs. Steam

iOS and Google Play mostly ask for gameplay screenshots and a couple of icons. Steam expects designed marketing art on top of that, and it expects it in a lot of shapes. A screenshot-only submission won't get through, because there's no capsule to show. If you're coming from mobile, budget time for a real logo and key art, and see Common Screenshot Mistakes for what carries over.

Resizing one piece of key art into all these shapes and repositioning text each time is slow. StoreShot's PC/Steam category can export a set of Steam-sized images from one piece of art. Check its output against the sizes in this article, which are the ones Valve currently documents.

FAQ

What are the current required capsule sizes?

Header Capsule 920×430, Small Capsule 462×174, Main Capsule 1232×706, and Vertical Capsule 748×896. All four are required.

Can I still upload the old, smaller capsule sizes?

No. After Valve doubled the sizes in August 2024, the old ones were accepted only until November 1, 2024. Uploads made before the change still work.

How many screenshots do I need and how big?

At least five, at a minimum of 1920×1080 in 16:9, showing gameplay only.

Can I put "50% off" or an award on my capsule?

No. Awards and review scores have dedicated sections on the store page, and discount text isn't allowed on base capsules. If you need update or event text, use an Artwork Override, which lasts at most one month and must be localized.

Can the Library Hero include my game title?

No. It must contain zero words. The transparent Library Logo (1280 px wide and/or 720 px tall PNG) sits on top of it, and key art such as faces should stay inside the centered 860×380 area.

Why don't my library assets show up?

Library assets only appear once your store page is published. Likewise, the App Icon shows in the store only after the page is published as Coming Soon or released.

Do screenshots need an age flag?

Yes. Mark at least four as suitable for all ages, or they may not appear in some areas, including the front-page hover.

Do all my capsules have to use the same art?

No. Valve says the Small Capsule art doesn't need to match the other capsules, so a simpler, logo-forward design is an option.
