Scope
Every term a studio meets while building a Steam store page: the five capsule types, the library assets, the written sections, the tags, and the metrics that judge them. For the workflow, see how to optimise your Steam store page.
A to Z
- About This Game
- The long description section below the fold on a Steam store page. Valve recommends its images be generated at 1170 px wide, caps animated assets at 12 seconds, and recommends keeping all screenshots and GIFs under 15 MB in total.
- Above the fold
- The part of a Steam store page a player sees without scrolling. On a standard 1080p monitor, Immutable defines it as the trailer, genre tags, short description, and first two to three carousel screenshots, a viewport-dependent heuristic rather than a fixed Steam layout.
- Artwork overrides
- Temporary capsule images that replace a game's default Steam store artwork between dates you set, then revert automatically. Valve says overrides are the only way to put text about major updates, tournaments, or other time-sensitive events onto a capsule.
- Capsule art
- The umbrella term for the promotional images Steam uses to represent a game across the store. Design criteria are covered in our guide to Steam capsule art, exact upload dimensions in Steam capsule sizes, and you can score an existing capsule 0 to 100 with our free Steam capsule analyser.
- Click-through rate (CTR)
- The share of players who see a game's capsule in a Steam list or rail and click through to the store page. Immutable's game CDP benchmark puts average indie capsule CTR below 2%, with titles clearing 4% earning meaningfully more visibility in discovery queues and search.
- Community Hub
- The discussions, screenshots, guides, and announcements space attached to a Steam game. Immutable recommends enabling and monitoring discussions before the Coming Soon page goes public, so prelaunch questions do not sit unanswered.
- Discovery Queue
- A Steam browsing surface that shows a player a personalised sequence of store pages one at a time. Valve lists it under organic visibility alongside Curator recommendations and publishes no detail on how titles are selected.
- Follower
- A player who has opted in to a game's updates on Steam, receiving announcements and events through their activity feed and the Steam News Hub. Following works through a mostly hidden game group, so follower counts are readable from that group's members page.
- Graphical Asset Rules
- Valve's rules for base store assets, which may carry only game artwork, the game name, and any official subtitle. Review scores, award logos, discount copy, promotion of other products, and extra text are prohibited.
- Header capsule
- The 920 x 430 px Steam capsule shown at the top of the store page, in Recommended For You, in Big Picture browse views, and for Daily Deals.
- Library capsule
- The 600 x 900 px portrait asset representing a game inside the Steam Library, including the library overview and collections. Steam auto-generates a 300 x 450 px half-size, and Valve asks that the logo stay legible against the background.
- Library header
- The 920 x 430 px asset used in Steam Client Library locations such as Recent Games. If you do not upload one, Steam falls back to the store header capsule.
- Library hero
- The 3840 x 1240 px banner across the top of a game's library details page, auto-generating a 1920 x 620 px half-size. Valve says it should read without text, and that critical content belongs inside the 860 x 380 px safe area because the image crops on resize.
- Library logo
- A transparent-background image of the game logo, 1280 px wide and/or 720 px tall, placed on top of the library hero. Valve offers four positions: bottom left, centred top, centred middle, centred bottom.
- Main capsule
- The 1232 x 706 px Steam capsule used in the Main Capsule carousel at the top of the store home page.
- Microtrailer
- A six-second clip Steam generates automatically from the first visible video on a store page. Developers cannot customise it, so the only control is trailer order: Steam shows the first two valid trailers above screenshots and lets you reorder them.
- Page background
- The 1438 x 810 px image that may be used behind a Steam store page. If you do not supply one, Steam generates it from your final screenshot.
- Popular Upcoming
- A Steam store tab of unreleased titles, one of the few exceptions Valve names to its statement that wishlists are not a factor in algorithmic visibility.
- Screenshots
- Steam requires at least five, uploaded at 1920 x 1080 minimum in 16:9. Valve says they should show actual gameplay and avoid concept art, pre-rendered cinematic stills, awards, and marketing copy.
- Short description
- The brief synopsis at the top of a Steam store page, also used in limited-space surfaces. Valve recommends focusing on the unique value proposition, naming the genre, using plain text, and avoiding time-based copy.
- Small capsule
- The 462 x 174 px capsule Steam uses in search results, top sellers, new releases, and similar lists, auto-rendered down to 184 x 69 and 120 x 45. Valve says the logo must stay legible at those sizes, which usually means it nearly fills the capsule.
- Store page conversion rate
- The share of store page visitors who take the action being optimised for, normally a wishlist add or a purchase. Immutable's analysis of 35B+ data points across 700+ games found top-performing teams optimise conversion rate rather than traffic volume alone. See Steam page conversion rate.
- Tag Wizard
- The Steamworks tool for setting tags, at Store Presence > Edit Store Page > Basic Info > Tags. It orders tag weights across genres, visual properties, themes and moods, and features, and needs Edit App Metadata plus Publish App Changes permissions.
- Tags
- Descriptive labels applied to a Steam game by developers, players, and moderators. Valve says the top 20 are visible and influence store visibility, the top 5 should clearly describe the game, and less common tags can outweigh broad ones in recommendations. See Steam tags.
- Vertical capsule
- The 748 x 896 px Steam capsule that can appear at the top of the front page during seasonal sales and on other sale pages.
- Wishlist
- A player's saved list of games they intend to buy. Wishlisters get an email or push notification when the game launches or leaves Early Access, and when it discounts 20% or more for over eight hours on the lowest-priced package, subject to a two-week cooldown per product.
How the terms group
The five capsules (header, small, main, vertical, library) are one asset family sized for five surfaces, commissioned together and judged at the size Steam renders them. Library capsule, header, hero, and logo are Steam Client assets rather than store assets, shaping how an owned game looks after purchase.
Short description, About This Game, tags, and screenshots form the written layer: positioning, confirmation, discovery routing, and proof.
The four studios most often confuse
Library capsule versus vertical capsule. Both portrait, neither interchangeable. The 600 x 900 px library capsule lives in the Steam Client Library; the 748 x 896 px vertical capsule is a store asset for sale pages.
Library header versus header capsule. Same 920 x 430 px dimensions, two upload slots. Skipping the library header is safe because Steam substitutes the header capsule; skipping the header capsule is not.
Wishlist versus follower.A wishlist is a purchase-intent signal triggering launch and discount notifications. A follow is a news opt-in putting announcements in a player's activity feed.
Wishlists versus visibility. Valve states wishlists are not a factor in algorithmic visibility, with a few exceptions such as Popular Upcoming. They earn notifications, not placement.
Sources: Steamworks documentation on store graphical assets, library assets, artwork overrides, tags, trailers, wishlists, followers and visibility on Steam, all fetched August 2026. The above-the-fold definition and the conversion-over-volume finding are Immutable's own; capsule click-through figures are directional benchmark data. Valve publishes no description of how the Discovery Queue selects titles, so none is given here.
