Getting your app preview video sizes right is crucial for App Store approval. Upload the wrong dimensions and Apple will reject your video. This guide covers all app preview video sizes, specs, and requirements for iPhone, iPad, Mac, Apple Watch, and Apple TV in 2026.
📐 App Preview Video Sizes (Quick Reference)
- iPhone 15 Pro Max (6.7"): 1290 × 2796 (portrait) / 2796 × 1290 (landscape)

Quick Answer: App Store preview videos must be H.264 or HEVC, 15-30 seconds, at specific resolutions matching each device size. Keep reading for the complete specs table.
Note: Tools like Matte handle these specs automatically — just select your target device and export. But understanding the requirements helps you troubleshoot issues and work with any tool.
Universal Requirements
Before diving into device-specific specs, here are the requirements that apply to all App Store preview videos:
- Duration: 15 to 30 seconds (no exceptions)
- Codec: H.264 or HEVC (H.265)
- Container: .mov or .mp4
- Frame rate: 30 fps (recommended for smoothest playback)
- Audio: Optional, but if included must be AAC, 256kbps or higher
- Color space: sRGB or P3
iPhone Preview Video Specs
Apple requires different resolutions for different iPhone display sizes. You'll need to create separate videos for each size class you want to support.
| Device | Resolution (Portrait) | Resolution (Landscape) |
|---|---|---|
| iPhone 15 Pro Max 6.7" Super Retina XDR |
1290 × 2796 |
2796 × 1290 |
| iPhone 15 Pro 6.1" Super Retina XDR |
1179 × 2556 |
2556 × 1179 |
| iPhone 14 Plus / 15 Plus 6.7" Super Retina XDR |
1284 × 2778 |
2778 × 1284 |
| iPhone 14 / 15 6.1" Super Retina XDR |
1170 × 2532 |
2532 × 1170 |
| iPhone SE (3rd gen) 4.7" Retina HD |
750 × 1334 |
1334 × 750 |
Pro tip: You typically only need to upload for the 6.7" and 6.5" display sizes. Apple will scale these for smaller devices. Focus your effort on the largest displays.
iPad Preview Video Specs
iPad preview videos follow similar rules but with different aspect ratios. Remember that many iPad users view apps in both portrait and landscape.
| Device | Resolution (Portrait) | Resolution (Landscape) |
|---|---|---|
| iPad Pro 12.9" (6th generation) |
2048 × 2732 |
2732 × 2048 |
| iPad Pro 11" (4th generation) |
1668 × 2388 |
2388 × 1668 |
| iPad Air (5th generation) |
1640 × 2360 |
2360 × 1640 |
| iPad (10th generation) |
1640 × 2360 |
2360 × 1640 |
| iPad mini (6th generation) |
1488 × 2266 |
2266 × 1488 |
Mac App Store Preview Specs
Mac apps have their own requirements. The good news is you have fewer size variations to worry about.
| Display Size | Resolution |
|---|---|
| Standard | 1920 × 1080 |
| Retina (recommended) | 3840 × 2160 |
Apple Watch & Apple TV Specs
Apple Watch
| Device | Resolution |
|---|---|
| Apple Watch Ultra (49mm) | 410 × 502 |
| Apple Watch Series 9 (45mm) | 396 × 484 |
| Apple Watch Series 9 (41mm) | 352 × 430 |
Apple TV
| Display | Resolution |
|---|---|
| Apple TV 4K | 3840 × 2160 (4K) or 1920 × 1080 (1080p) |
Common Spec Mistakes to Avoid
- Wrong aspect ratio — Recording at 16:9 when iPhone needs ~9:19.5. Always match the exact device resolution.
- Videos too short or long — Exactly 15-30 seconds. Not 14.9 seconds. Not 30.1 seconds.
- Using variable frame rate — Some screen recorders use VFR. App Store Connect may reject these. Use constant 30 fps.
- Incorrect color profile — Stick to sRGB for maximum compatibility, or P3 if your app specifically uses wide color.
- Letterboxing or pillarboxing — Black bars around your video will get it rejected. Fill the frame completely.
Export Settings Cheat Sheet
Whether you're using Final Cut Pro, DaVinci Resolve, or another editor, here are the settings to use:
- Codec: H.264 (High Profile) or HEVC
- Bitrate: 15-30 Mbps for 1080p, 40-60 Mbps for 4K
- Frame rate: 30 fps constant
- Audio (if used): AAC, 256 kbps, stereo
- Container: .mp4 or .mov
HEVC vs H.264: HEVC produces smaller files at the same quality, but H.264 has better compatibility. When in doubt, use H.264.
How Many Videos Do You Need?
You can upload up to 3 preview videos per device size. Here's a practical approach:
- Minimum: One video for the largest iPhone (6.7") and one for iPad Pro 12.9"
- Recommended: Add the 6.1" iPhone size to cover all modern devices well
- Complete: All device sizes, localized for each language
For most indie developers, creating videos for 2-3 device sizes is sufficient. Apple scales videos down gracefully.
Skip the Spec Headaches
Matte automatically exports at the correct app preview video sizes for every device. Just select your target and export.
Try Matte FreeTesting Your Videos
Before uploading to App Store Connect:
- Check the file info — Right-click and verify resolution, codec, and duration
- Play it back — Watch for any encoding artifacts or audio sync issues
- Preview the thumbnail — The first frame becomes your poster. Make it count.
- Test on actual devices — How does it look on an iPhone screen?
Final Thoughts
Getting the specs right is table stakes — it just gets you past the upload. What really matters is the content of your video: showing your app's best features in 30 seconds or less.
