The Ultimate Guide to App Store and Google Play Asset Sizes in 2026

If you’re reading this, you probably know the exact feeling: you’ve spent weeks, maybe months, designing and coding the perfect app. You’ve ironed out the bugs, polished the UI, and you’re finally ready to hit that glorious "Publish" button. But then, you hit a wall. Both the Apple App Store and the Google Play Store demand a bewildering array of correctly sized, specifically formatted image assets before they’ll even let you submit your creation.

Keeping track of these ever-changing requirements can feel like a full-time job. In 2026, the stores have evolved yet again, introducing new device categories, updated masking rules, and stricter quality standards. Whether you’re an indie developer shipping your first project or a seasoned UI/UX designer streamlining your agency’s workflow, this comprehensive guide will demystify exactly what sizes you need today.

And more importantly, we’ll show you how to generate all of them instantly without ever opening a clunky photo editor.

The Google Play Store Requirements: Your Android Asset Checklist

Google’s ecosystem is vast, spanning phones, tablets, televisions, and wearables. To ensure your app looks stunning across every potential touchpoint, the Play Console requires several key assets.

1. The High-Res App Icon (512 × 512 px)

This is the holy grail of your Android presence. It’s what users see when they search the store, browse top charts, and ultimately tap to launch your app.

- Dimensions: 512 × 512 pixels

- Format: 32-bit PNG (with alpha)

- Max File Size: 1024 KB

- The Catch: Do not add rounded corners or drop shadows yourself! Google Play automatically applies a standardized squircle mask and drop shadow to your uploaded square image. If you upload a pre-rounded icon, it will look terrible. Keep it square.

2. The Feature Graphic (1024 × 500 px)

Often underestimated, the Feature Graphic is arguably your most important marketing asset. It sits at the top of your store listing and is the first thing potential users see. Think of it as a billboard for your app.

- Dimensions: 1024 × 500 pixels

- Format: JPEG or 24-bit PNG (no alpha/transparency)

- Best Practices: Keep text and important visual elements centered. Avoid placing crucial info near the edges, as it might get cropped on certain device displays.

3. The Android TV Banner (1280 × 720 px)

If your app supports Android TV, a banner is mandatory. It acts as the app’s icon on the television interface.

- Dimensions: 1280 × 720 pixels

- Format: JPEG or 24-bit PNG

4. Wear OS Icon (384 × 384 px)

With the booming popularity of smartwatches, supporting Wear OS is a must for many apps. Wear OS requires a dedicated circular icon.

- Dimensions: 384 × 384 pixels

- Format: PNG

- Masking: Your design must account for a circular crop. Crucial elements must fit within the center circle, or they will be cut off on the user’s wrist.

The Apple App Store Requirements: iOS, iPadOS, and Beyond

Apple is notorious for its strict adherence to design guidelines. Their asset requirements are meticulous and require precision.

1. The Master App Store Icon (1024 × 1024 px)

This is the primary icon uploaded to App Store Connect. Apple uses this master file to generate various sizes for different contexts.

- Dimensions: 1024 × 1024 pixels

- Format: PNG (no alpha/transparency)

- The "Squircle" Rule: Like Google, Apple demands a completely square, full-bleed image with no transparency. Apple’s system automatically applies their proprietary continuous curve (the famous "superellipse" or squircle) mask. Do not pre-round your corners!

2. iPad Pro App Icon (167 × 167 px)

While the master 1024x1024 icon does a lot of heavy lifting, you often need specific sizes for your Xcode project bundle, particularly for iPad Pro models.

- Dimensions: 167 × 167 pixels

- Format: PNG

3. iPhone Spotlight Search Icon (120 × 120 px)

When a user swipes down to search their phone, your app’s icon needs to look crisp.

- Dimensions: 120 × 120 pixels (for @3x displays)

- Format: PNG

4. watchOS App Icon (1024 × 1024 px)

Apple Watch apps require their own specific icon assets. While submitted at 1024x1024, they are ultimately displayed within a circular mask on the watch face.

- Dimensions: 1024 × 1024 pixels

- Format: PNG (no transparency)

The Old Way: A Workflow Nightmare

Historically, generating these assets has been a tedious, soul-crushing chore.

The traditional workflow goes something like this:

1. Open a heavy, expensive program like Adobe Photoshop or a clunky alternative like GIMP.
2. Create a new file for the Google Play icon.
3. Import your logo.
4. Scale it down, hoping the interpolation doesn't make it blurry.
5. Export as PNG.
6. Create a new file for the Feature Graphic.
7. Realize the aspect ratio is completely different. Re-design the graphic to fit 1024x500.
8. Export as JPEG.
9. Repeat this process for iPad, Spotlight, Wear OS, and watchOS.

This manual process is incredibly prone to errors. It’s easy to accidentally export with transparency when a store forbids it, or to mess up the aspect ratio, resulting in a stretched, amateurish icon. Worst of all, it takes you out of your flow state and wastes hours of valuable development time.

The New Way: The Store Asset Resizer

We recognized that developers and designers were wasting too much time on this repetitive task. That’s why we built ReinShots Studio—a dedicated, web-native tool designed to eliminate the headache of app store assets forever.

With ReinShots Studio, the workflow is brilliantly simple:

1. Select Your Store: Choose between the Android or iOS preset categories.

3. Upload Once: Drag and drop your high-resolution logo or graphic into the browser.
4. Adjust and Preview: Use your mouse wheel to zoom and simply drag the image to reposition it perfectly within the crop frame.
5. Smart Masks: If you select a Wear OS or watchOS preset, our tool automatically overlays a circular visual guide. If you select an iOS icon, we overlay the exact ~22.37% Apple squircle mask. You see exactly how your icon will look in the wild before you export.
6. Download: Click a button to download the perfectly sized, perfectly formatted file.
