1. Why App Store Screenshot Sizes Matter
App Store screenshots are the single most influential visual element in your product page. According to marketplace research data, over 70% of visitors decide to download an app based on the screenshot gallery alone — before reading a single line of the description. Getting your screenshot dimensions wrong means rejected submissions, blurry visuals, or wasted screen real estate.
The store console updates required sizes whenever new hardware tiers launch. This guide covers the exact pixel specifications required for App Store Connect in 2026, including the mandatory and optional display classes.
2. Required Smartphone Screenshot Sizes (2026)
As of 2026, the developer console requires screenshots for two primary smartphone display classes. If you only submit one set, the system will attempt to auto-scale them — but this frequently causes blurry typography or misaligned borders.
| Display Class | Portrait (W × H) | Landscape (W × H) | Hardware Class |
|---|---|---|---|
| 6.9" Display (Required) | 1320 × 2868 px | 2868 × 1320 px | Modern flagship large displays |
| 6.5" Display (Required) | 1284 × 2778 px | 2778 × 1284 px | Modern standard large displays |
| 5.5" Display (Optional) | 1242 × 2208 px | 2208 × 1242 px | Legacy home-button displays |
The 6.9" display uses a slightly taller 19.55:9 aspect ratio compared to the 6.5" display's 19.5:9. While the difference is small, App Store Connect strictly enforces exact pixel counts. You cannot upload a 1284 × 2778 image into the 6.9" slot — it will be rejected immediately.
3. Required Tablet Screenshot Sizes (2026)
If your app binary supports tablet devices, you must provide tablet screenshots. Tablet product pages display screenshots with a wider aspect ratio, making smartphone captures look distorted if stretched.
| Display Class | Portrait (W × H) | Landscape (W × H) | Hardware Class |
|---|---|---|---|
| 13" Display (Required) | 2064 × 2752 px | 2752 × 2064 px | Modern large tablet displays |
| 11" Display (Optional) | 1668 × 2420 px | 2420 × 1668 px | Modern compact tablet displays |
4. File Format & Color Space Specifications
App Store Connect enforces strict technical constraints on every uploaded image file:
| Property | Specification | Notes |
|---|---|---|
| Format | PNG or JPEG | PNG is strongly recommended for crisp typography and vector bezels. |
| Color Space | sRGB or Display P3 | Never use CMYK — it causes washed-out colors on retina screens. |
| Resolution | 72 dpi | DPI metadata doesn't affect quality; pixel count is what matters. |
| Transparency | None (No alpha channel) | Images with transparent pixels will be rejected with an upload error. |
| Max File Size | 50 MB per image | ReinShots exports optimized PNGs typically between 1–3 MB. |
| Max Screenshots | 10 per display class | The first 3 are the most important for organic conversion. |
A frequent cause of App Store upload failure is having an alpha channel in your PNG file, even if the image looks fully opaque. If your export tool saves a 32-bit PNG with an unused transparency layer, App Store Connect will show: "Images cannot contain transparency." ReinShots automatically flattens all exports to 24-bit RGB, preventing this error completely.
5. Status Bar & Home Indicator Safe Zones
When designing mockups that feature device bezels and text overlays, you must account for system safe zones:
- Top Notch / Dynamic Island Zone: Leave at least 160–180 pixels of vertical breathing room from the top edge. If you place your marketing headline too high, it may feel crowded or overlap with store UI chrome.
- Bottom Home Indicator Zone: Leave at least 100 pixels at the bottom. Avoid placing vital text, button callouts, or critical disclosures along the bottom border.
- Edge Margins: Maintain at least 60–80 pixels of left and right padding. Modern phone displays feature curved corner radiuses that clip content placed flush against corners.
6. How to Avoid Automated Upload Rejections
App Store Connect runs automated image validation checks upon upload. Here is how to pass on your first attempt:
- Verify Pixel Dimensions: Ensure width and height match the table exactly. A 1320 × 2868 image cannot be 1320 × 2869.
- Remove Transparency: Confirm files are flattened 24-bit PNG or 24-bit JPEG.
- Check Color Profiles: Embed standard sRGB profiles to ensure consistent color rendition across OLED displays.
- Keep Text Legible: Ensure font sizes remain readable at search feed scale. Read our Typography Tips Guide for optimal sizing formulas.
