Wrong pixel dimensions are one of the most common App Store Connect upload failures. Apple accepts only specific width × height pairs, rejects alpha channels, and scales missing slots from larger sets—so uploading the right required sizes (and knowing when optional sizes are worth the extra work) saves hours of rejection loops.
This guide maps Apple’s current App Store Connect screenshot specifications for iPhone and iPad, clarifies required vs optional, and gives a practical export checklist for indie teams and mobile marketers.
According to Apple’s App Store Connect screenshot specifications:
1179 × 2556 or 1206 × 2622 (portrait; swap for landscape).2064 × 2752 or 2048 × 2732 (portrait; swap for landscape)..jpeg, .jpg, or .png — no alpha / transparency.Apple also documents a large Dynamic Island class (commonly discussed as the 6.9″ set) and a Face ID large class (the classic 6.5″ set). If you omit the large Dynamic Island set, App Store Connect can fall back to scaled 6.5″ assets in some slots—and the 6.5″ class itself is marked required when large Dynamic Island screenshots are not provided. In practice, most teams upload one high-resolution iPhone set and one 13″ iPad set, then let Connect scale down for smaller phones and tablets.
Use portrait dimensions below; landscape is the same pair swapped. Device lists are Apple’s class membership, not a guarantee that every model ships at that physical diagonal.
| Display class | Accepted portrait sizes (px) | Typical role |
|---|---|---|
| Dynamic Island large (≈6.9″) | 1260 × 2736, 1290 × 2796, 1320 × 2868 | Best “master” set for modern Max/Plus/Air-class phones |
| Face ID large (≈6.5″) | 1284 × 2778, 1242 × 2688 | Required if large Dynamic Island set is missing |
| Dynamic Island medium (≈6.3″) | 1179 × 2556, 1206 × 2622 | Required minimum for iPhone submission |
| Face ID medium (≈6.1″) | 1170 × 2532, 1125 × 2436, 1080 × 2340 | Optional; scales from larger sets |
| Home Button large (5.5″) | 1242 × 2208 | Optional legacy |
| Home Button medium (4.7″) | 750 × 1334 | Optional legacy |
| Home Button 4″ / 3.5″ | 640 × 1136 / 640 × 960 (status-bar variants exist) | Optional legacy |
Practical recommendation: Export your marketing frames at 1320 × 2868 or 1290 × 2796 when you want one master that looks sharp after scaling, and ensure App Store Connect still has a valid medium Dynamic Island upload for the required slot—either by uploading that size explicitly or confirming Connect’s scaling fills it from your larger assets as your account UI allows.
Apple groups devices by upload slot, not marketing names:
Always verify the exact accepted sizes in App Store Connect → your version → Screenshots before a release freeze—Apple updates class membership as new hardware ships.
| Display | Portrait sizes (px) | Requirement |
|---|---|---|
| 13″ | 2064 × 2752, 2048 × 2732 | Required if the app runs on iPad |
| 12.9″ | 2048 × 2732 | Optional; scales from 13″ if empty |
| 11″ | 1488 × 2266, 1668 × 2420, 1668 × 2388, 1640 × 2360 | Optional; scales from 13″ |
| 10.5″ | 1668 × 2224 | Optional |
| 9.7″ | 1536 × 2048 / 1536 × 2008 (status-bar variants) | Optional |
If your UI is the same across iPad sizes, one 13″ set is enough. Upload dedicated 11″ frames only when scaled 13″ crops important chrome (split views, sidebars, keyboard layouts).
Apple’s rule of thumb: if the UI is consistent across device sizes and localizations, provide screenshots for the highest required resolution and let Connect scale down. You can override any slot with device-specific images when scaled results look soft, crop captions, or misrepresent iPad multitasking.
Localization note: screenshots can be localized per language. App previews fall back to the “next best” available language when a localization is missing—screenshots should still be planned for your highest-traffic locales.
Before you batch-export:
A lean process that works for most universal apps:
Tools such as appshotmaker.com can generate multi-size exports from one design pass; whatever stack you use, treat Apple’s pixel list as the source of truth.
| Mistake | Symptom | Fix |
|---|---|---|
| Exporting 1080 × 1920 “Play size” to iOS | Dimension error | Re-export to an accepted Apple pair |
| PNG with alpha | Upload rejected | Flatten to opaque PNG/JPEG |
| Only uploading 6.1″ frames | Missing required slots | Add medium Dynamic Island and/or large set |
| Stretching 6.5″ to 6.9″ | Soft UI, wrong aspect | Redesign on the target canvas |
| Same phone frames on iPad | Misleading product page | Rebuild for 13″ aspect and UI |
Screenshot specs move when Apple ships new displays. Before every major release:
Get the sizes right once, automate exports, and spend your creative energy on conversion—not on rejection emails about wrong dimensions.
