Google Play screenshots are easier than App Store screenshots in one way: Google does not ask for exact iPhone-style device pixel sizes. It checks format, dimensions, aspect ratio, and whether the image actually represents the app.
The hard requirements
- JPEG or 24-bit PNG. Do not upload transparent PNGs.
- Minimum dimension: 320 px.
- Maximum dimension: 3840 px.
- The long side cannot be more than twice the short side.
- You need at least two screenshots to publish the listing.
Google also lets you upload up to eight screenshots for each supported device type. For a phone-first app, ship the phone set first, then add tablet and Chromebook assets when the app is actually good on large screens.
The practical phone size
Use 1080×1920 for portrait phone screenshots. It is a clean 9:16 ratio, meets Google's recommended minimum for high-quality display, and is easy to reuse in ads, landing pages, and press kits.
What Google checks visually
The screenshot should show the current app experience. Google warns against blurry, distorted, stretched, repetitive, or misleading assets. Taglines are allowed, but keep them short and avoid store-performance claims such as "best", "top", or "#1".
Source notes
Google's current preview asset help page documents the 320 px minimum, 3840 px maximum, JPEG or 24-bit PNG format, and the max-side-to-min-side ratio rule. The same Google docs recommend at least four 1080 px screenshots for app recommendation surfaces.
