Free Steam Capsule AnalyzerScore your capsule art in seconds

It's the image Steam uses to represent your game everywhere a player can find it: search results, the front page, recommendation rails, the library. You upload a few source sizes and Steam renders them all over the store, usually far smaller than you designed them. For most games, the capsule is the single most-seen piece of marketing art they will ever ship.

Four uploads: header 920 × 430, small 462 × 174, main 1232 × 706, and vertical 748 × 896. The trap is that Steam auto-shrinks the small capsule to a 120 × 45 thumbnail for search and discovery, and that postage stamp is where most of your impressions happen. Design for 120 × 45 first, then scale up.

Five things, in rough priority order: a title you can still read at 120 × 45, one focal point instead of three, strong value contrast against Steam's dark #1b2838 background, a genre signal a player can name in under a second, and a look that doesn't blend into the other games in your genre. Fine detail, lore references, and taglines all die at thumbnail size.

Six dimensions – genre clarity, title readability, contrast and color, uniqueness and polish, brand consistency, and composition – each scored 1-10 against published anchors, judged at full, small, and tiny render sizes. Your 0-100 score is the straight average of the six, times ten. The full rubric, anchors, and formula are published on the methodology page, so you can check the math yourself.

Yes, through one specific mechanism: click-through rate. The capsule decides whether a player clicks through to your page at all, and every wishlist starts with that click. It's one of the highest-leverage assets on your store page and usually the cheapest to fix. One honest caveat: a great capsule gets players to the page – your screenshots, trailer, and description still have to convert them.

Yes. Upload the art directly and you'll get the same six-dimension score and ranked fixes with no store page required. Scoring your capsule before launch is the cheap time to fix it – after launch, every day of a weak capsule is discovery traffic you don't get back.

Yes. The capsule earns the click; everything else on the page spends it. A better trailer behind a capsule nobody clicks is a better trailer nobody watches. Fix the capsule first, then work down the page.
