Best App Store Screenshot & Preview Video Sizes (2026)
App Store Connect and Google Play both enforce specific dimensions for screenshots and preview videos. Here's what to use so your assets pass review without a resubmission.
Try Mockly FreeAspect ratio comes first
Both stores accept portrait (9:16) and landscape (16:9) orientations for phone and tablet listings, matched to how your app is actually used. Pick the orientation your app runs in by default rather than mixing both in the same listing.
Video specs that hold up
Preview videos need to be H.264 MP4 — exactly what Mockly exports. Export at 1080p for a standard listing, or 4K if you want headroom for the video to also be reused on a website or in ad creative.
A simple workflow
Take your existing screenshot at native resolution, upload it to Mockly, pick the matching device frame and aspect ratio, and export. You don't need a separate device farm or simulator recording to get store-accurate dimensions.
Frequently asked questions
They should share the same orientation and aspect ratio as your screenshots for a consistent listing, though the exact pixel dimensions can differ slightly since video and image specs are validated separately.
Both stores will reject an upload that doesn't match an accepted aspect ratio, requiring a re-export — checking your ratio in Mockly's canvas settings before exporting avoids that delay.
1080p is sufficient for App Store and Play Store playback; export 4K only if you plan to reuse the same file somewhere that benefits from higher resolution, like a website hero.
