How to Post Vertical Videos on X (Twitter) in 2025
Direct Answer: X now features a dedicated Vertical Video tab in its camera interface, making it easier than ever to post vertical-format videos directly to your feed or X Premium subscribers.
Step-by-Step: Posting Vertical Videos on X in 2025
1. Open the Compose Box
Click the "+" (compose) icon in X's left sidebar, or tap the quill icon in the mobile app.
2. Select the Media Icon
Click or tap the gallery/media icon within the compose box.
3. Choose Your Vertical Video
X automatically detects video orientation. Select your vertical video file (9:16 aspect ratio is standard). The platform now shows a "Vertical" badge on compatible uploads.
4. Post or Schedule
- Post now: Add your caption, hashtags, and tags, then hit Tweet.
- Schedule: Use X's native scheduler or third-party tools like Calabi to queue vertical videos for optimal engagement times.
5. Verify Vertical Display
After posting, check that your video plays full-screen vertically in the feed. If it appears cropped or rotated, re-export your video with correct orientation metadata.
Quick Tips for Vertical Videos on X
| Tip | Why It Matters |
|---|---|
| Use 9:16 aspect ratio | Fills mobile screens, higher watch time |
| Keep under 60 seconds | Better completion rates |
| Add captions | 80%+ watch without sound on mobile |
| Front-load your hook | First 1-3 seconds must grab attention |
| Post at 6 AM or 6 PM local time | Peak mobile usage windows |
Troubleshooting Common Issues
Video posted as landscape? Re-encode your video with a forced vertical flag. Most editing apps (CapCut, DaVinci Resolve) can reset orientation metadata.
X compression making quality poor? Export at 1080x1920 minimum, 30fps, using H.264 codec. Keep file size under 512MB for best results.
Vertical Video tab not showing? Update your X app to the latest version. The feature rolled out in phases through 2024-2025.
What's Changed in 2025
X has prioritized vertical video in its algorithm, pushing full-screen vertical content higher in feeds than square or landscape uploads. The platform also introduced:
- Vertical Video Monetization: Creators can now earn ad revenue specifically on vertical video plays
- X Premium Video Integration: Longer vertical videos (up to 3 hours) now available to Premium+ subscribers
- Auto-crop Assist: X suggests optimal crop points for horizontal footage you want to reformat
Best Practices for Engagement
- Lead with text overlays — since most viewers scroll without sound
- Use the first frame strategically — make it thumb-stopping
- Include a call-to-action — "Follow for more" or "Link in bio"
- Cross-post from TikTok/Reels — vertical videos port directly, though re-editing for X's faster pace improves results
Ready to streamline your X video workflow? From scheduling to analytics, managing vertical video across platforms is simpler with the right toolkit.
