Microsoft Store screenshots, every device class in one pass

The Microsoft Store screenshot rulebook, in one preset

Microsoft Partner Center is the developer portal that powers the Microsoft Store across Windows 11, Windows 10, and Xbox-app surfaces. The desktop screenshot spec is 1366×768 px floor and 1920×1080 px recommended upload target — that resolution matches the most-common Windows display class and renders crisp across the Store-app surface on every modern Windows install. For high-DPI / 4K listings, 3840×2160 is supported and recommended on premium games and pro apps. The aspect ratio is 16:9 landscape with no mixing allowed across a single listing's screenshot set — every screenshot in the listing should match. PNG is preferred for transparency / alpha edge cases (required for the Brand Logo slot) and JPEG is fine for typical full-frame app captures. The per-image cap is a generous 50 MB. Hero / promotional images live in separate slots — Square Boxart (1080×1080), Tall Boxart (720×1080), Wide Boxart (1920×1080), Brand Logo (1080×1080 with alpha) — and Xbox-distributed games carry additional hero requirements. The mobile / phone-class screenshot slot from the Windows 10 Mobile era (9:16 portrait at 720×1280 minimum) is practically deprecated as the desktop catalogue is now the primary surface.

The rules that move Microsoft Store certification review are mostly about accurate representation, locale alignment, and competitor-platform separation. Misleading content — a screenshot showing a feature, UI, or activity not in the shipping binary — is the highest-friction rejection reason under Policy 11.5 (Imagery), and the certification team is empirically strict about it. Common pitfalls include showing a Pro-tier feature on a free listing, showing a desktop-only feature on a mobile-class screenshot, and showing in-development UI not yet shipped. Apple / iOS / Google Play branding is forbidden on Microsoft Store listings — any iPhone device frame, iOS Settings UI, Apple App Store badge, Google Play badge, or competitor app screenshot gets the listing rejected at certification. Per-storefront caption text must be in the storefront's distribution language; English captions on the JP / KR / ZH-CN / ZH-TW storefronts get rejected. Right-to-left layouts (Arabic, Hebrew) require chrome-layer flip. Adult content is forbidden on Store screenshots even on apps rated for mature audiences because the rendering surface is age-class-blind. The preset's chrome-layer separation keeps the in-app capture independent of the caption and frame, so locale-aligned localisation, RTL flips, and per-version caption edits don't require full re-renders.

Why a complete localised screenshot set drives more Microsoft Store installs

Microsoft Store's funnel is short — search or category browse to listing card to install — and the listing card decides most installs. The first 2-3 screenshots show on the card without scrolling and they carry the highest install-conversion weight. Apps that ship the full 9 screenshots × 15 storefronts outperform listings with the minimum 1-2 screenshots, because the broader set lets prospects evaluate features, UI quality, and language support across the storefronts they actually buy in. Localisation matters disproportionately on the storefronts where in-language captions are the floor for trust signals — Japan, Korea, Greater China, and the right-to-left markets in particular. Apps that skip localised captions on those storefronts quietly cap their install ceiling at the English-tolerant subset of the local audience. AAA games and Xbox-distributed titles see the steepest install-volume gains from complete asset bundles (screenshots + every Boxart slot + Brand Logo with alpha) because the Xbox-app surface and the Microsoft Store homepage feature listings with complete asset coverage. Running the full set through the preset before the next Partner Center upload is the cheapest install-volume lift available without changing the binary itself.
