Steam asks for more than a dozen images, each at an exact size, and since September 2022 it has strict rules about what may appear on them. This is the whole set in one place: every store capsule, library asset and event image, where each one shows up, and the text rules that can cost you visibility. Checked against the Steamworks documentation on 22 Oct 2026.
These are the images people see before they ever reach your page. All four are required, and Valve asks you to use the same key art and logo as the rest of your marketing.
| Asset | Size (px) | Where it shows |
|---|---|---|
| Header capsule | 920 x 430 | Top of your store page, Recommended For You, Big Picture browse views, Daily Deals |
| Small capsule | 462 x 174 (Steam makes 184 x 69 and 120 x 45 from it) | Search results, top sellers, new releases and most lists |
| Main capsule | 1232 x 706 | The Main Capsule carousel at the top of the Steam home page |
| Vertical capsule | 748 x 896 | Top of the front page during seasonal sales, and on sale pages |
| Page background | 1438 x 810 (optional) | Behind your store page. Without one, Steam uses your last screenshot |
| Screenshots | 1920 x 1080 minimum, 16:9, at least 5 | Store page gallery and the hover preview |
Design the small capsule first. It is the one most players see, in search and in every list, and Steam shrinks it to 120 x 45. Valve says the logo should nearly fill it. If the title is unreadable at that size, the other capsules will not save it.
These appear in the Steam client once someone owns or plays the game. The hero is cropped on different screens, so keep anything important inside the 860 x 380 safe area in the middle.
| Asset | Size (px) | Rule |
|---|---|---|
| Library capsule | 600 x 900 PNG | Logo and optional subtitle only |
| Library header | 920 x 430 PNG | Branding first, logo clearly legible |
| Library hero | 3840 x 1240 PNG, safe area 860 x 380 | Artwork only, no text at all |
| Library logo | 1280 wide and/or 720 tall, transparent PNG | Your logotype and optional logomark, no other words |
Every update, sale or festival announcement you post through the events tools needs a cover image. The icons are set once in the community section of your app.
| Asset | Size (px) | Used for |
|---|---|---|
| Event cover image | 800 x 450 | Announcements and events on the store page, event lists and the library |
| Event header image | 1920 x 622 | Top of an event detail page (suggested, not required) |
| App icon | 184 x 184 JPG | Library list view, chat, notifications, Steam Deck |
| Shortcut icon | 256 x 256 or 512 x 512, ICO or PNG | Desktop shortcuts |
Since 1 September 2022, base capsules may show only the game's artwork, its name and an official subtitle. Valve lists what is not allowed:
All capsules, store and library, must have a readable logo or name, the exact dimensions and PG-13 appropriate artwork. Valve's own wording on the penalty: a game that breaks these rules "may have limits to visibility within the Steam store and will be ineligible for featuring in official Steam sales and events."
To show a big update, a seasonal event, a battle pass or new DLC on your capsules, upload the special images as an Artwork Override in the Graphical Assets tab. Pick a start and end time, and the capsules switch back to the default art on their own afterwards.
Capsules get people to your page. What they see when they arrive decides the wishlist. At the very top, above the screenshots, Steam can show a live broadcast player that starts playing on its own. Most pages leave it empty. What a store broadcast is explains how it works, and the broadcast setup checklist gets one running. Loopcast keeps it live around the clock from our servers, so no PC has to stay on.
For everything else your page needs before review, work through the Steam store page checklist.
