Steam Game Page Requirements: Every Asset, Size and Spec

Steam requires six store capsules, four library assets, two icons, at least five screenshots at 1920x1080, and a trailer no larger than 1920x1080, and every dimension below was read off Valve’s own documentation on September 15, 2026. Wrong dimensions, wrong formats, or missing assets get your page bounced at review, and Valve asks you to “submit your request for review at least 7 business days before you want your page live”, so a bounce costs real calendar.

Key facts

• •Store capsules: header 920x430, small 462x174, main 1232x706, vertical 748x896, page background 1438x810, bundle header 707x232 (Steamworks graphical assets documentation, read September 15, 2026).
• •Library assets: library capsule 600x900, library header 920x430, library hero 3840x1240 with an 860x380 centred safe area, library logo up to 1280 wide and/or 720 tall on transparency (Steamworks library assets documentation, same date).
• •“You must provide at least 5 screenshots of your product,” minimum 1920x1080 at 16:9. The median page across the 405 we benchmarked from February 10 to July 30, 2026 carries 9 (Steam Store Pages in Numbers).
• •The trailer ceiling is 1920x1080, not 4K: “the highest resolution that you have, up to 1920 x 1080 resolution, 30/29.97 or 60/59.94 fps” (Steamworks trailer documentation, same date).
• •Text rules are absolute where Valve states them: the library hero “image cannot include any text”, and the library logo may carry only your logotype and an optional logomark.

This guide is a complete reference for every asset you need, with exact dimensions, format requirements, and practical notes on what Valve actually checks. Bookmark it and work through it systematically. For the design principles behind these assets, our capsule design guide and screenshot optimization guide go deeper on making them perform well - and for a capsule-only quick reference with the current upload dimensions, see the Steam capsule sizes table. This post is about getting the full spec list right.

Capsule images are the visual backbone of your Steam presence. They appear everywhere - search results, discovery queues, wishlists, the front page, sale events, recommendations, and your game’s library entry. Each capsule size serves a different context, and you can’t simply resize one image across all of them. The aspect ratios are different, which means you need to plan compositions that work at multiple sizes.

A critical point that trips up first-time developers: Valve has strict rules about what can appear on capsules. Your game’s title and artwork are fine. Review scores, award logos, “Game of the Year” text, discount percentages, and marketing copy are generally not allowed on most capsule types. Violating these rules is one of the most common rejection reasons.

Run all your capsules through our Capsule Validator before submitting. It checks dimensions, file format, and file size instantly, so you can catch problems before Valve does.

Header Capsule - 920 x 430 pixels

• •Dimensions: 920 x 430 px (displays at 460 x 215)
• •Format: PNG or JPG
• •Where it appears: Top of your store page, “Recommended for you” widgets, Big Picture mode, Daily Deals
• •Requirements: Must include your game’s title. Must be legible at display size. No review quotes or award logos.
• •Notes: This is the capsule players see most often. You upload at 920 x 430, but most placements render it at 460 x 215, so check your art at that size before submitting - and no upscaling from smaller sources. The title must be readable without squinting.

Small Capsule - 462 x 174 pixels

• •Dimensions: 462 x 174 px (displays at 231 x 87, 184 x 69, and 120 x 45)
• •Format: PNG or JPG
• •Where it appears: Search results, top sellers, new releases, wishlists, small recommendation widgets, bundle pages
• •Requirements: Must include your game’s title. Must be legible at its smallest display sizes.
• •Notes: This is the hardest capsule to get right. You upload at 462 pixels wide, but Steam renders it at 231 x 87 in search results and as small as 120 x 45 in some widgets - detail gets lost fast at those sizes. Simplify your composition dramatically compared to larger capsules. If your game title uses a thin or decorative font, it may be unreadable here - consider a simplified version of your logo for this slot. Test it by viewing it at 231 x 87 and 120 x 45 on your screen, not zoomed in.

Main Capsule - 1232 x 706 pixels

• •Dimensions: 1232 x 706 px (displays at 616 x 353)
• •Format: PNG or JPG
• •Where it appears: Featured spots on the front page, sale event pages, “New and Trending,” “Top Sellers” lists
• •Requirements: Must include your game’s title. This is your primary promotional image.
• •Notes: The main capsule gets the most screen real estate in high-traffic locations. It’s worth spending extra time on this one. The larger dimensions give you room for more visual detail, but don’t overcomplicate it - the composition still needs to read quickly at the 616 x 353 display size.

Vertical Capsule - 748 x 896 pixels

• •Dimensions: 748 x 896 px (displays at 374 x 448)
• •Format: PNG or JPG
• •Where it appears: Seasonal sale front pages and some promotional layouts
• •Requirements: Must include your game’s title. Portrait orientation (roughly 5:6).
• •Notes: This is the slot that keeps your game from looking letterboxed during the Summer Sale and other event features. Compose for the portrait frame directly - a cropped header capsule looks awkward here. It’s a different aspect ratio from the library capsule’s 2:3, so don’t assume one portrait image covers both.

Page Background - 1438 x 810 pixels (optional)

• •Dimensions: 1438 x 810 px
• •Format: PNG or JPG
• •Where it appears: Behind your store page content, visible at the edges on wide screens
• •Requirements: Subtle, atmospheric art that won’t compete with the page content sitting on top of it.
• •Notes: A common mix-up: there is no separate “hero banner” upload for the top of your store page - the big 3840 x 1240 hero image is the Library Hero, covered below. The page background is the only store-level background slot, it’s optional, and most of it gets covered by the page itself, so put mood and texture here rather than anything that needs to be seen.

Library Capsule - 600 x 900 pixels

• •Dimensions: 600 x 900 px
• •Format: PNG or JPG
• •Where it appears: A player’s Steam library (the vertical game list)
• •Requirements: Must include your game’s title. Vertical/portrait orientation.
• •Notes: Along with the vertical capsule, this is one of the two portrait slots, and its 2:3 ratio needs a distinct composition from your landscape capsules. Every player who owns your game sees it regularly. Steam auto-generates a 300x450 half-size version.

Library Hero - 3840 x 1240 pixels

• •Dimensions: 3840 x 1240 px
• •Format: PNG or JPG
• •Where it appears: Background image in a player’s library when your game is selected
• •Requirements: Wide atmospheric image. Valve’s rule is absolute: this “image cannot include any text”. Your logo is overlaid separately.
• •Notes: This is the big cinematic banner people often call the “hero graphic” - it lives in the library, not on your store page. The library UI overlays your logo and play controls on top of it, and it crops aggressively at different window widths, so keep critical art inside the 860 x 380 center safe area.

Library Logo - up to 1280 wide and/or 720 tall

• •Dimensions: Up to 1280 px wide and/or 720 px tall
• •Format: PNG (with transparency)
• •Where it appears: Overlaid on the library hero image when your game is selected
• •Requirements: Your game’s logo on a transparent background. Should be readable against various background colors.
• •Notes: Provide your logo at the highest resolution that fits within those limits. Steam will scale it down as needed, and you choose its position over the hero in a Steamworks preview tool. Make sure it reads clearly against both light and dark backgrounds since the hero image behind it can vary.

Community Icon - 32 x 32 pixels

• •Dimensions: 32 x 32 px
• •Format: PNG or JPG
• •Where it appears: Steam community features, discussion boards, group pages
• •Requirements: Must be recognizable at this tiny size.
• •Notes: At 32 pixels, you can’t use your full logo. Use a simplified icon, a recognizable symbol from your game, or your developer logo. Think of it like a favicon.

Client Icon - 16 x 16, 32 x 32, and other ICO sizes

• •Dimensions: ICO file containing multiple sizes (16x16, 32x32, and optionally larger)
• •Format: ICO
• •Where it appears: The Steam client taskbar and desktop when your game is running
• •Requirements: Standard ICO file with multiple resolutions embedded.
• •Notes: Windows ICO format. Include at least 16x16 and 32x32 versions. This is the icon players see when your game is running in their taskbar.

Screenshots are typically the second thing players examine after your capsule image (or first, if they skip the trailer). They carry a lot of weight in the purchase decision. Our screenshot optimization guide covers composition strategy, but here are the technical requirements.

Technical specifications

• •Minimum count: 5 screenshots required. 8-10 recommended.
• •Minimum resolution: 1920 x 1080 pixels (1080p).
• •Maximum resolution: No hard cap, but 3840 x 2160 (4K) is the practical upper limit.
• •Format: PNG or JPG. PNG preferred for pixel art games; JPG is fine for 3D games.
• •Aspect ratio: 16:9 is standard and strongly recommended. Other ratios are supported but may display awkwardly in Steam’s layout.
• •File size: No hard limit, but keep individual files under 5MB for faster loading.

Content requirements

• •Must show actual gameplay. Not concept art, not pre-rendered cinematics, not promotional mockups. Players expect to see what the game actually looks like when they’re playing it.
• •No watermarks or overlay text. No developer logos, no “ALPHA BUILD” banners, no marketing text. Steam’s UI provides context - your screenshots should be clean.
• •No borders or letterboxing. Fill the full image area with game content.
• •First screenshot matters most. It displays as the default image when your trailer isn’t playing and appears in various browse contexts. Make it your strongest, most representative shot.

Screenshot recommendations

Show variety: different environments, mechanics, UI states, and gameplay moments. UI shots matter more than most galleries allow for. Across 220 full analyzer reports written between February 10 and September 14, 2026, 140 (63.6%) asked for a UI, menu or systems screenshot the page did not have, the most common gap of any category (the first-screenshot study). Make sure the art style in the shots is the art style you ship; misleading screenshots lead to refunds and negative reviews.

Use our Screenshot Checker to verify your screenshots meet all technical requirements before uploading.

Your trailer is the highest-impact asset on your store page. Players who watch your trailer are significantly more likely to wishlist or purchase. Our trailer best practices guide covers creative strategy, but here are the specs.

Technical specifications

• •Resolution: “the highest resolution that you have, up to 1920 x 1080”. 1080p is the ceiling Valve states, not the floor, so do not upload 4K.
• •Frame rate: 30/29.97 or 60/59.94 fps.
• •Format: .mov, .wmv or .mp4 at a high bit rate (5,000+ Kbps); “H.264 video and AAC audio is preferred”.
• •Aspect ratio: 16:9 preferred, 4:3 accepted.
• •Length: Valve states no maximum. 60-90 seconds is the indie convention.
• •Audio: Valve transcodes to stereo, so mix for stereo and assume many viewers watch muted.

All six lines above are quoted or paraphrased from Valve’s trailer documentation, read September 15, 2026.

Trailer requirements

• •At least one trailer is strongly recommended. Technically you can publish without one, but your page will underperform dramatically.
• •Trailer must accurately represent the game. Don’t use footage from a different build that looks significantly better than what you’re shipping.
• •No ESRB or other rating logos. Steam has its own content descriptor system.
• •First trailer auto-plays. Whichever trailer you set as primary will auto-play when players visit your store page. Make it your best one.

Multiple trailers

You can upload multiple trailers (gameplay, announcement, update trailers). Order them intentionally - the first one in the list auto-plays and should be your strongest. Update trailers are useful for keeping your page fresh after launch, but they shouldn’t replace your primary gameplay trailer.

Profile features (optional but recommended)

• •Trading Card art: If you’re implementing Steam Trading Cards, each card needs front artwork (206 x 184 px) and a badge icon.
• •Achievement icons: 64 x 64 px for each achievement. Upload both locked and unlocked versions.
• •Emoticons: 54 x 54 px per emoticon, if you’re creating custom Steam emoticons.
• •Profile backgrounds: 1920 x 1080 px. These are rewards players can earn and display on their Steam profiles.

These assets aren’t required for your page to go live, but they enhance the overall player experience and give your game more presence across the Steam ecosystem. Trading cards in particular generate ongoing engagement and a small amount of ongoing revenue through the Steam marketplace.

Use this as your master checklist. Don’t submit for review until every required item is ready.

Understanding why Valve rejects store page submissions helps you avoid the same mistakes - run a rejection notice through our Steam page review check to match its wording against Valve’s own rules.

Capsule image issues

Wrong dimensions is the most basic error and it still happens constantly. Double-check every capsule against the exact pixel requirements listed above. Even 1 pixel off can trigger a rejection. The Capsule Validator catches this instantly.

Prohibited content on capsules is the next most common. Review scores, award logos, “Game of the Year” badges, discount percentages, and excessive marketing text are not allowed on most capsule types. Your capsule should feature your game art and title - that’s it.

Unreadable title at small display sizes. The Small Capsule uploads at 462x174 but displays as small as 120x45 - if your game title isn’t legible at display size, it will be rejected. Test at actual display size, not zoomed in.

Low quality or compression artifacts. Blurry, pixelated, or heavily compressed capsules signal low effort and will be flagged. Upload the highest quality sources you can.

Screenshot issues

Not actual gameplay. Concept art, promotional renders, and heavily composited images that don’t represent real gameplay will be rejected.

Watermarks or overlay text. Developer logos, build version numbers, and marketing text on screenshots are not allowed.

Too few screenshots. You need at least 5. Less than that and you won’t pass review.

Trailer issues

Misleading footage. If your trailer shows content that isn’t representative of the actual game, it can be flagged. This includes using footage from a significantly more polished build than what you’re shipping.

Missing or incorrect content descriptors. If your trailer contains mature content that isn’t reflected in your content survey, it creates a mismatch that triggers review issues.

Here’s the workflow I’d recommend for getting all your assets ready efficiently.

Step 1: Gather source material. Capture high-resolution screenshots and gameplay footage. Get the highest quality versions of your logo and key art. Work from the best sources you have.

Step 2: Create capsules from largest to smallest. Start with the Main Capsule (1232x706) since it has the most screen real estate, then adapt the composition for Header (920x430), Small (462x174), Vertical (748x896 - portrait), Library (600x900 - portrait), and Hero (3840x1240 - ultra-wide). Don’t just resize - re-compose each one for its specific dimensions. Validate all of them with the Capsule Validator.

Step 3: Select and order screenshots. Choose your strongest 8-10 shots, put the most compelling one first, and make sure you’re showing variety. Run them through the Screenshot Checker.

Step 4: Edit your trailer. Cut to 60-90 seconds, show gameplay within the first 10 seconds, and end with a clear call to action. Export at 1080p minimum.

Step 5: Prepare remaining assets. Community icon, client icon, library logo. These are small but still required.

Step 6: Internal review. Before submitting to Valve, have someone who hasn’t seen your store page review everything with fresh eyes. They’ll catch issues you’ve gone blind to.

For the full submission process and what happens after you upload these assets, our guide to publishing on Steam walks through every step.

What file format should I use for capsule images?

PNG is the safest choice for all capsule images. It preserves quality without compression artifacts, which is especially important for text readability and pixel art. JPG is acceptable, but use high quality settings (90%+) to avoid visible compression. For the Library Logo specifically, PNG with transparency is required.

Can I update my assets after my page is live?

Yes, and you should. Update your screenshots, capsules, and trailer as your game improves during development. Each update goes back through review, and Valve asks you to “submit your request for review at least 7 business days before you want your page live” (Steamworks Coming Soon documentation, read September 15, 2026), so budget that lead time rather than assuming a same-week turnaround.

Do I need different capsule compositions or can I crop one image?

You need different compositions. The aspect ratios across capsule sizes are different - the header capsule (920x430) is roughly 2:1, while the library capsule (600x900) is 2:3 portrait. A single image cropped to fit each size will look awkward at best and unreadable at worst. Plan at least two compositions: one for landscape capsules and one for the portrait slots - and note the vertical capsule (748x896, roughly 5:6) and library capsule (600x900, 2:3) are different enough ratios that one portrait image rarely covers both cleanly. The Library Hero (3840x1240) needs its own ultra-wide composition as well.

What resolution should my screenshots be?

1920 x 1080 (1080p) is the minimum for a professional-looking store page. 2560 x 1440 (1440p) or 3840 x 2160 (4K) screenshots look noticeably sharper and give you more flexibility when Steam displays them at various sizes. If your game can render at higher resolutions, take your screenshots at the highest resolution available.

How many trailers should I have?

One strong gameplay trailer is the minimum. Two to three is ideal - a primary gameplay trailer, plus an announcement or story trailer, and potentially an update trailer if you’ve made significant improvements since the original. Quality matters more than quantity. One excellent trailer outperforms three mediocre ones.

What happens if my capsule dimensions are slightly off?

Valve will reject your submission. They’re exact about pixel dimensions. Even being 1-2 pixels off can trigger a rejection. Use the Capsule Validator to verify before uploading. It takes seconds and saves you days of waiting through an unnecessary review cycle.

Getting your assets right the first time saves days of review back-and-forth and gives your store page the strongest possible foundation. Start with the Capsule Validator to verify your images meet specs, use the Screenshot Checker for your gameplay shots, and review our capsule design guide and trailer best practices for the creative principles behind effective assets.
