Steam Store Graphic Sizes: The Complete 2026 Guide
Putting a game on Steam means preparing a completely different set of graphic assets than you would for a mobile store. Beyond screenshots, your Steam page is built out of capsule images, header images, library images, and a handful of other formats with names that sound unfamiliar the first time you run into them. Steamworks specs get revised from time to time, so this guide walks through the sizes that are current as of 2026.
What Is a Capsule Image?
A "capsule" is the small thumbnail that represents your game across Steam's list-style screens — search results, tag pages, wishlists, recommendation widgets, and pretty much anywhere your game shows up as an image rather than plain text. Because these placements come in different sizes, you'll need to prepare several versions of the same artwork, each composed for its specific slot.
| Asset | Size | Where It Shows Up |
|---|---|---|
| Header Capsule | 920 × 430px | Top of the store page (required) |
| Main Capsule | 1232 × 706px | Featured lists, store page cards (required) |
| Small Capsule | 462 × 174px | Search results, tag lists, and other spots where multiple games line up in a row (required) |
| Vertical Capsule | 748 × 896px | Card-style layouts that display games vertically |
| Hero Capsule | 3840 × 1240px | Ultra-wide promotional banners |
| Library Capsule | 600 × 900px | Vertical cover art shown in a user's Steam library after purchase |
| Library Header | 920 × 430px | Header for the library detail screen |
| Screenshot | 1920 × 1080px (16:9, 1280×720 minimum) | Actual gameplay captures |
| Page Background | 1438 × 810px | Background image behind the store page |
A note on legacy sizes: older guidance called for just two capsule sizes — 460×215px and a 231×87px small capsule. Those have since been replaced by the three required sizes above (920×430 header, 1232×706 main capsule, 462×174 small capsule), and vertical capsules, hero capsules, and the page background have been added on top. If you're working from an old template or a bookmarked forum post, double-check it against current Steamworks documentation before you build anything.
Where Each Asset Actually Shows Up
The 920×430 header capsule is the first large banner visitors see when they land on your store page, so it usually carries your logo or title treatment and does the heaviest lifting for establishing your game's identity.
The 1232×706 main capsule appears in relatively large placements, so it's typically built around a single striking piece of key art that communicates genre and art style at a glance.
The 462×174 small capsule shows up much smaller, often lined up next to a dozen other games at once. At that size, color and silhouette do more work than text or fine detail — keep any headline short, and consider dropping a subhead entirely for the sake of readability.
The 3840×1240 hero capsule is an ultra-wide promotional banner, and a centered title treatment tends to work best given the extreme aspect ratio.
The 600×900 library capsule is a tall, vertical cover shown to players who have already bought your game and are launching it from their library. Since this audience has already converted, the image can lean into atmosphere and identity rather than a sales pitch.
How This Differs from Mobile Stores
iOS and Google Play build their listings mostly around actual gameplay screenshots. Steam leans much more heavily on purpose-designed graphics like capsules and headers. Gameplay captures alone won't get you through Steam registration — in most cases you'll also need dedicated logo design and banner-style artwork that doesn't exist anywhere in the game itself.
Pre-Launch Checklist
| Check | Details |
|---|---|
| Three required capsules | Header (920×430), main capsule (1232×706), small capsule (462×174) all prepared |
| Vertical / hero capsules | Composed separately for their 748×896 and 3840×1240 placements |
| Library capsule / header | 600×900 and 920×430 built with their own layouts, not reused from the store page |
| Screenshots | 1920×1080 (16:9, 1280×720 minimum), captured from real gameplay |
| Page background | 1438×810 |
Resizing one piece of key art into every capsule size — and repositioning text each time — takes longer than it looks. StoreShot's PC/Steam category lets you drop in your art and copy once and export all nine Steam sizes, including the three required capsules, as a single ZIP — no phone mockups involved.
Takeaway
Steam simply asks for more graphic assets than a mobile store does. Start with the three required sizes — header (920×430), main capsule (1232×706), and small capsule (462×174) — then build the vertical capsule, hero capsule, library capsule/header, and page background as separate compositions from the start. Treating each one as its own layout, rather than a resized version of another asset, saves time in the long run.
