App Store Screenshot Sizes 2025: Complete iOS & Android Guide

Why screenshot sizes matter more than you think

Screenshots are the single highest-converting element on any app listing. Studies by StoreMaven and SplitMetrics consistently show that 50–70% of visitors decide to install — or leave — based on screenshots alone, before reading a single word of your description.

But submit the wrong size, and Apple will reject your build outright. Submit the right sizes in the wrong aspect ratio, and Google Play will crop them in ways that make your app look broken. This guide gives you every dimension, every format rule, and explains why each one exists.

iOS App Store screenshot sizes (2025)

Apple requires screenshots in JPEG or PNG format (no alpha channel / transparency), at 72 DPI, with no rounded corners applied by you — the App Store adds those automatically. Maximum 10 screenshots per device type; minimum 1 (though 4–8 performs best in A/B tests).

Portrait vs. landscape

If your app is portrait-only (most apps), submit all screenshots in portrait. If it supports landscape, submit both orientations. The first screenshot in your set is the one shown in search results — make it your strongest.

App previews (video)

Apple also supports short video previews (15–30 seconds, max 500MB, H.264 or HEVC). These autoplay on the product page and in search. If you have a demo video, upload it — it significantly boosts conversion for games and utility apps.

Google Play screenshot sizes (2025)

Google Play is more flexible than Apple on exact sizes, but has its own rules. Screenshots must be JPEG or PNG, between 320px and 3840px on the longest side, with an aspect ratio between 2:1 and 1:2. That said, the industry standard is 1080×1920px (portrait 9:16).

Google Play icon requirements

Your app icon on Google Play must be 512×512px PNG with alpha (transparency allowed, unlike iOS). This is separate from the icon in your APK/AAB — it's the store listing icon specifically.

Mac App Store screenshot sizes

Mac screenshots must be JPEG or PNG, and Apple requires at least one screenshot in the 1280×800 size. Retina versions are optional but strongly recommended since most modern Macs have Retina displays.

Common mistakes that get screenshots rejected

• Wrong aspect ratio: The most common reason for App Store rejection. A 1290×2796 screenshot submitted at the wrong crop will fail validation immediately.
• Alpha channel on iOS: Apple doesn't allow transparency in screenshots. Flatten your PNG before submitting — any alpha will cause a rejection.
• Rounded corners: Don't add them yourself. The App Store applies device-specific corner masks. If you pre-round, the result looks doubled on the device frame.
• Too small text: Apple recommends text no smaller than 10pt at actual size. Screenshots with unreadable text often get flagged during app review.
• Missing feature graphic (Android): If you skip the 1024×500 banner, Google Play may show a blank or auto-generated placeholder — which looks unprofessional in search results.
• Wrong file size: iOS screenshots have no explicit size limit, but Android screenshots must be under 8MB per image.

What makes a high-converting screenshot

Getting the pixels right is just the start. Here's what actually moves installs:

• Lead with the outcome, not the feature. "Track your expenses effortlessly" outperforms "Expense tracking" every time. The first screenshot is your headline.
• Use captions. 70% of users don't read the description at all. Short, punchy caption text on each screenshot communicates value in seconds.
• Show the real UI. Generic mockups with lorem ipsum text convert far worse than actual app screens with real data.
• 5 screenshots is the sweet spot. Studies show diminishing returns past 5 — most users won't swipe past the fourth anyway.
• Localize. Translating caption text into the language of each App Store market can increase conversion rates by 20–40% in non-English markets.
