What size is an App Store preview video?
Not your screen's size. Most previews start as screen recordings, so Apple accepts a short list of standard sizes for each group of devices and asks you to use those, not the device's own resolution:
- iPhone with Face ID or Dynamic Island, and iPhone Duo: 886 × 1920 in portrait, or 1920 × 886 in landscape.
- iPhones with a Home Button: 1080 × 1920 for the 5.5-inch and 4-inch groups, 750 × 1334 for the 4.7-inch group. The 3.5-inch group can't have previews.
- iPad: 1200 × 1600 in portrait, or 1600 × 1200 in landscape. The 9.7-inch group takes 900 × 1200, and the 12.9-inch group takes either.
- Mac and Apple TV: 1920 × 1080, landscape only.
- Apple Vision Pro: 3840 × 2160, landscape only.
So a video exported at your iPhone's screen size, such as 1206 × 2622, won't do. Drop it into the checker and it tells you the size to export at instead.
How long can an app preview be?
Between 15 and 30 seconds. Apple lists both ends as requirements.
Apple says previews autoplay with the sound off on your product page, so make the first few seconds work without sound. When a video doesn't play, people see its poster frame instead. That's the frame at 5 seconds unless you pick another one in App Store Connect.
What are all the accepted iPhone sizes?
| Apple's name | Often called | Portrait | Landscape | If it has none, Apple uses |
|---|---|---|---|---|
| iPhone Duo | Not used | 886 × 1920 | 1920 × 886 | None listed |
| iPhone with Dynamic Island (large display) | 6.9-inch | 886 × 1920 | 1920 × 886 | iPhone with Face ID (large display) |
| iPhone with Face ID (large display) | 6.5-inch | 886 × 1920 | 1920 × 886 | iPhone with Dynamic Island (large display) |
| iPhone with Dynamic Island (medium display) | 6.3-inch | 886 × 1920 | 1920 × 886 | iPhone with Face ID (large display) |
| iPhone with Face ID (medium display) | 6.1-inch | 886 × 1920 | 1920 × 886 | iPhone with Dynamic Island (medium display) |
| iPhone with Home Button (large display) | 5.5-inch | 1080 × 1920 | 1920 × 1080 | iPhone with Face ID (medium display) |
| iPhone with Home Button (medium display) | 4.7-inch | 750 × 1334 | 1334 × 750 | iPhone with Home Button (large display) |
| iPhone with Home Button (4-inch display) | 4-inch | 1080 × 1920 | 1920 × 1080 | iPhone with Home Button (medium display) |
| iPhone with Home Button (3.5-inch display) | 3.5-inch | No previews | No previews | No previews |
The last column is Apple's: if a group has no preview of its own, the App Store shows a scaled copy of that group's. The inch sizes are the names most makers search for, matched from each group's device list, so treat Apple's names as the rule.
What are the accepted iPad sizes?
| Apple's name | Often called | Portrait | Landscape | If it has none, Apple uses |
|---|---|---|---|---|
| iPad 13-inch display | 13-inch | 1200 × 1600 | 1600 × 1200 | None listed |
| iPad 12.9-inch display | 12.9-inch | 1200 × 1600, 900 × 1200 | 1600 × 1200, 1200 × 900 | iPad 13-inch display |
| iPad 11-inch display | 11-inch | 1200 × 1600 | 1600 × 1200 | iPad 13-inch display |
| iPad 10.5-inch display | 10.5-inch | 1200 × 1600 | 1600 × 1200 | iPad 12.9-inch display |
| iPad 9.7-inch display | 9.7-inch | 900 × 1200 | 1200 × 900 | iPad 10.5-inch display |
What about Mac, Apple TV and Vision Pro?
| Apple's name | Portrait | Landscape |
|---|---|---|
| Mac | Landscape only | 1920 × 1080 |
| Apple TV | Landscape only | 1920 × 1080 |
| Apple Vision Pro | Landscape only | 3840 × 2160 |
All three take landscape only. Apple Watch isn't on the list: Apple offers previews for iOS, macOS, tvOS and visionOS apps.
Which formats, frame rate and file size does Apple accept?
- H.264 in a .mov, .m4v or .mp4 file: progressive, up to High Profile Level 4.0, with a target bit rate of 10 to 12 Mbps.
- ProRes 422 (HQ only) in a .mov file: progressive, no external references, about 220 Mbps.
- 30 frames per second at most, for both.
- 500 MB at most per file.
HEVC isn't on the list, and the checker flags it. If your recording is at 60 frames per second, export it again at 30.
What sound does an app preview need?
For H.264 files Apple asks for:
- Stereo, as 256 kbps AAC, at 44.1 or 48 kHz.
- One track with two channels (left, then right), or two tracks with one channel each (left, then right).
- All tracks enabled.
ProRes files can use PCM at 16, 24 or 32 bits instead of AAC. Since previews play muted by default, Apple's app preview advice is to put the key points on screen as text too.
Apple's specification lists these sound settings but doesn't say a preview must have sound. If yours has no sound track, the checker says so and doesn't count it as a problem.
How many app previews can I upload?
Up to 3 per device size and language. They're optional. On iPhone, iPad, Mac and Apple TV they show before your screenshots, whatever order you set. A preview with a different shape from your screenshots goes in the "A Closer Look" section of the product page instead.
Apps on the App Store for iMessage can't have previews. After you upload one, processing can take up to 24 hours. You add them on the version page or in Asset Library in App Store Connect.
Do I need a separate preview for every device?
No. If your app looks the same on every size, Apple says to upload only the highest resolution it asks for, and it scales that down for smaller devices. You can still add previews for other sizes and languages. If a language has no preview of its own, the App Store shows the one in the next best language.
What should a preview show?
Only the app. Guideline 2.3.4 says previews may only use screen captures of the app itself, though narration and text or video overlays are fine. Apple's app preview advice adds a few more: keep it suitable for all ages, don't film hands or a device, leave out prices, and say so when a feature needs a purchase, a subscription or a login.
Screenshots have their own sizes and rules. The screenshot size checker checks those.
What does the checker look at?
It reads the file's header in your browser, the part of a .mov or .mp4 file that describes what's inside, without uploading anything:
- Resolution, against every size in the tables, with the size to export at when it's off.
- Length, against 15 to 30 seconds.
- Format, from the file's type and extension.
- File size, against 500 MB.
- Codec: H.264 with its profile and level, against High Profile Level 4.0, or which ProRes flavour it is. HEVC and other codecs are flagged.
- Frame rate, from the file's own frame timing, so it's exact. If the frame rate changes, it checks the fastest stretch.
- Sound: codec, channels and tracks, sample rate, PCM bit depth, the AAC bit rate and whether every track is enabled. No sound track is fine.
- Video bit rate, shown next to Apple's target for reference.
If the header can't be read, it falls back to what your browser's video player reports, estimates the frame rate from a few seconds of playback, and says plainly what it couldn't check. It never passes a file it couldn't read.
What can't this tool check?
- Progressive or interlaced. Apple asks for progressive video, and the checker doesn't read the scan type. Nor does it check ProRes files for external references.
- Left and right. It counts channels and tracks, but can't tell whether the first one is really the left.
- What's in it, and App Store Connect's last word. If App Store Connect disagrees with this page, it wins. Tell us and we'll fix it.
