1. The 2026 Mobile Asset Landscape: Precision Over Compromise
Every software developer and designer knows the exhilaration of preparing an app for release: weeks or months of architecture, coding, unit testing, and design iterations have culminated in a production-ready build. Yet countless launches stall at the final hurdle: the developer console asset submission form.
Both major mobile platform storefronts enforce strict, non-negotiable visual asset gates. Submitting an image that is a single pixel off-dimension, has an accidental 8-bit alpha channel, or places text within an uncalibrated hardware notch area results in immediate automated submission rejection or soft server-side downsampling that blurs your marketing message.
In 2026, the proliferation of modern display resolutions—ranging from ultra-dense 6.9-inch smartphone displays to 13-inch productivity tablets, foldable devices, and wearable screens—makes an organized asset strategy indispensable. This master reference provides exact specifications and safe-zone rules to guarantee flawless asset validation across every storefront.
2. iOS Master Asset Specification Table
App Store Connect categorizes screenshot upload slots according to physical screen diagonal classes. The following table provides the required pixel resolutions, aspect ratios, and format requirements:
| Device Category | Required Dimensions | Aspect Ratio | File Format | Mandatory / Optional |
|---|---|---|---|---|
| Modern 6.9-inch Smartphone | 1320 × 2868 px (Portrait) 2868 × 1320 px (Landscape) 1290 × 2796 px also accepted |
19.5:9 | 24-bit PNG / JPEG (No alpha) | Optional, recommended as the master size. Scaled down for smaller phones |
| Modern 6.3-inch Smartphone | 1206 × 2622 px (Portrait) 2622 × 1206 px (Landscape) 1179 × 2556 px also accepted |
19.5:9 | 24-bit PNG / JPEG (No alpha) | Named as the required phone size |
| Foldable Smartphone | 1398 × 2034 px (Outer display) 2007 × 2853 px (Inner display) |
~11:16 / ~5:7 | 24-bit PNG / JPEG (No alpha) | Optional now; required from April 2027 for apps built with the iOS 27.1 SDK or later |
| Modern 6.7-inch Smartphone | 1290 × 2796 px (or 1284 × 2778 px) | 19.5:9 | 24-bit PNG / JPEG | Covered by 6.9" slot via auto-scaling |
| Modern 6.5-inch Smartphone | 1284 × 2778 px (Portrait) 2778 × 1284 px (Landscape) 1242 × 2688 px also accepted |
19.5:9 | 24-bit PNG / JPEG | Required only if no 6.9" set is uploaded |
| Legacy 5.5-inch Smartphone | 1242 × 2208 px (Portrait) | 16:9 | 24-bit PNG / JPEG | Optional legacy fallback |
| 13-inch Pro Tablet Display | 2064 × 2752 px (Portrait) 2752 × 2064 px (Landscape) 2048 × 2732 px also accepted |
4:3 | 24-bit PNG / JPEG | Mandatory if tablets are supported |
| Legacy 12.9-inch Tablet Display | 2048 × 2732 px (Portrait) 2732 × 2048 px (Landscape) |
4:3 | 24-bit PNG / JPEG | Accepted in tablet slot |
| Master App Store Icon | 1024 × 1024 px | 1:1 (Square) | 24-bit PNG (100% Opaque) | Mandatory for all listings |
App Store Connect scales screenshots down from the highest resolution you upload, so a 6.9-inch set (1320 × 2868) fills the smaller phone slots automatically. The current specification names the medium 6.3-inch slot (1206 × 2622) as the required phone size, so export that size as well. Together with a 2064 × 2752 tablet set, those three exports cover a typical phone and tablet app. For the full slot-by-slot breakdown, see our detailed App Store screenshot sizes reference.
3. Android & Play Console Asset Specification Table
The Google Play Console accommodates a wider variety of hardware aspect ratios, but imposes strict upper and lower dimension bounds and requires distinct promotional graphics (our Play Store screenshot sizes reference covers every form factor in detail):
| Asset Type | Dimensions & Bounds | Aspect Ratio | File Constraints | Mandatory / Optional |
|---|---|---|---|---|
| High-Res App Icon | 512 × 512 px | 1:1 | 32-bit PNG (with alpha), Max 1024 KB | Mandatory |
| Feature Graphic | 1024 × 500 px | ~2:1 (1024:500) | JPEG or 24-bit PNG (No alpha), Max 15 MB | Mandatory for store discovery |
| Phone Screenshots | Each side 320–3840 px; long side ≤ 2× short side (Standard: 1080 × 1920 px) |
9:16 up to 1:2 (e.g. 1080 × 2160) | JPEG or 24-bit PNG (no alpha), max 8 MB each, 2 to 8 images | Mandatory (Min 2 images) |
| 7-inch Tablet Screenshots | Each side 1080–7680 px (e.g., 1080 × 1920 px) |
9:16 or 16:9 | JPEG or 24-bit PNG, 4 to 8 images | Optional; needed to show a tablet layout |
| 10-inch Tablet Screenshots | Each side 1080–7680 px (e.g., 1440 × 2560 px) |
9:16 or 16:9 | JPEG or 24-bit PNG, 4 to 8 images | Optional; needed to show a tablet layout |
| Android TV Banner | 1280 × 720 px | 16:9 | JPEG or 24-bit PNG | Mandatory if Android TV is supported |
4. The 1024x500 Feature Graphic Blueprint
The Feature Graphic is arguably the highest-visibility billboard on your Google Play listing. It sits at the top of your product detail page, serves as the background for promotional video trailers, and appears in curated editorial collections across the Play Store.
However, many developers design the Feature Graphic like a static banner ad, which results in critical content being chopped off. The Play Store client dynamically crops the outer 15% of the canvas depending on whether the user is browsing on a phone, tablet, or desktop web browser.
Feature Graphic Safe-Zone Rules
- Center Primary Messaging: Keep your app logo, primary illustration, and value proposition within the central 800 × 400 pixel safe zone.
- Avoid Text Near Edges: Keep at least 60 pixels of empty margin along the top and bottom borders, and 100 pixels along the left and right edges.
- Never Duplicate Pricing Claims: Avoid adding text like "Free App" or star rating icons to the Feature Graphic; Google Play guidelines prohibit promotional pricing tags on graphic assets.
5. Master App Icons: Safe Zones & Squircle Masks
Both major mobile operating platforms require a master square graphic (1024x1024 for iOS and 512x512 for Android) but apply drastically different runtime processing:
- Never Pre-Round Your Corners: Upload completely square artwork with sharp 90-degree corners. The mobile operating system applies its own continuous squircle mask dynamically at runtime. Pre-rounding produces ugly dark corner artifacts.
- Observe the 80% Safe Zone: Position all vital iconography within the central 80% boundary (~820px on a 1024px canvas, or ~410px on a 512px canvas). Because super-ellipses curve deeper than simple circles, corner details will be amputated if they venture outside this boundary.
- Eliminate Alpha Transparency for iOS: App Store Connect rejects 1024x1024 icons with an embedded alpha channel. The canvas must be 100% opaque.
6. Wearables & Connected TV Requirements
If your mobile application extends to smartwatch or television hardware, prepare these dedicated assets:
- Smartwatch Platform Icons: Require circular crops (384 × 384 px or 1024 × 1024 px master). All essential branding must fit within a central circular mask, as the outer 30% of the canvas is discarded.
- Connected TV Banners: Require a 16:9 landscape banner (1280 × 720 px or 1920 × 1080 px). Design for a 10-foot viewing distance with bold, legible logomarks and minimal small-print text.
7. Manual Photo Editor Bottlenecks vs. ReinShots Studio
Creating and resizing every asset variant manually in Photoshop or GIMP is an exhausting, error-prone workflow. A typical cross-platform launch requires 15 to 25 distinct images. If a single button color or headline copy changes, repeating the manual export pipeline across dozens of files wastes valuable hours.
ReinShots Studio was engineered to eliminate this friction entirely. With ReinShots, you configure your screenshots, device bezels, and typography once in your browser. The system includes built-in presets for every required dimension. With a single click, the WebGL rendering engine exports a neatly organized, mathematically verified asset package at full resolution completely offline.

What are the required smartphone screenshot sizes for major app stores in 2026?
On the App Store, the required medium phone slot takes 1206 x 2622 or 1179 x 2556 pixels, and the large 6.9-inch slot takes 1320 x 2868 pixels (1290 x 2796 and 1260 x 2736 are also accepted). Google Play accepts phone screenshots where each side is between 320 and 3840 pixels and the long side is at most twice the short side, so 1080 x 1920 (9:16) or 1080 x 2160 (2:1) work, while 20:9 formats such as 1080 x 2400 are rejected.
What are the exact dimensions for the store Feature Graphic?
The primary store Feature Graphic requires exactly 1024 x 500 pixels in JPEG or 24-bit PNG format (maximum 15 MB, zero alpha channel). It acts as the hero billboard across product pages and curated editorial recommendations.
Should I round the corners of my app store master icon before upload?
No. Master icons must be uploaded as 100% square images (1024x1024 for iOS or 512x512 for Android) with sharp 90-degree corners and zero transparency. Platform ingestion systems automatically apply their proprietary continuous squircle or adaptive corner masks.
What tablet screenshot dimensions are required?
For large 13-inch flagship tablets, upload 2064 x 2752 pixels in portrait (or 2752 x 2064 in landscape). For 10-inch and 7-inch Android tablets, provide screenshots with minimum edges of 1080px maintaining standard 4:3 or 16:10 aspect ratios.
How can I generate all required store assets in one workflow?
Using ReinShots Studio, you can import your master UI screenshots once and export perfectly formatted, pixel-compliant assets across every smartphone, tablet, and feature graphic preset in a single automated batch.
