indielySee your capsule where players actually see it: on the shelf.
Artwork designed on a full-screen canvas looks completely different next to ten competing games. Drop in your capsule artwork right here—no login needed—to see how your contrast, silhouette and title stand out on a simulated Steam shelf.
Drop PNG/JPG
Instant in-browser preview. Test contrast, font legibility and color balance against simulated dark Steam UI (#171a21).
Never evaluate a capsule in isolation.
Players never see your capsule floating against a plain white background. They see it flanked by colorful, professional titles, discount banners and Steam's dark grey interface.
The Dark-on-Dark Trap
Steam's background is dark slate grey (#171a21). Capsules with deep black or muddy backgrounds lose their borders and appear smaller on the page.
Thumbnail Legibility
Most Steam traffic encounters the 462 × 174 small capsule. If your game title is unreadable at small scale, browsing players scroll right past it.
Genre Silhouette
At a glance, a viewer should feel the genre—whether horror, cozy management or fast action. Comparing next to genre leaders highlights whether your artwork communicates instantly.
Test across three standard Steam formats.
Switch between the Main Capsule (1232 × 706), Small Capsule (462 × 174) and vertical formats. Inspect how the visual hierarchy holds up as the display size shrinks on desktop and mobile viewports.
Compare with real competitor releases.
Place your game alongside popular releases in your genre. Check whether your focal point grabs the eye first or gets drowned out by vibrant neighboring artwork.
Fix the artwork, then run a blind test.
Once your capsule reads clearly on the shelf, verify current dimensions in the Capsule Size Guide, refine layers in Capsule Studio, and run an A/B test to get real participant feedback.
Steam shelf simulator questions
Why does my capsule look different on a Steam shelf than in my image editor?
Steam displays capsules at smaller scales against a dark slate background (#171a21) surrounded by bright competitor artwork and price badges, which can wash out dark borders and thin typography.
Can I preview my Steam capsule here without creating an account?
Yes. Drag and drop any PNG, JPEG or WebP capsule directly onto the shelf preview on this page. The image stays in your browser and is never uploaded to a server.
What capsule sizes should I test in the shelf simulator?
Start with the Header Capsule (920 × 430) and Small Capsule (462 × 174), since those appear most frequently in search results, tag lists and recommendation rows.
