Video Aspect Ratios for YouTube, Instagram, TikTok & Every Platform (2026 Guide)
Last updated: April 20268 min readCalculator Tools
YouTube uses 16:9 (1920×1080). Instagram Reels and TikTok use 9:16 (1080×1920). Instagram feed videos can be 1:1 (1080×1080) or 4:5 (1080×1350). Here is every video aspect ratio for every platform in 2026.
Upload the wrong aspect ratio and your video gets letterboxed, pillarboxed, auto-cropped, or just looks wrong. Every platform has specific ratio requirements, and they change more often than you would expect. This is the definitive reference for 2026.
Every Platform's Video Specs
This is the table you will bookmark. Every major platform, every video format, exact dimensions.

| YouTube | Shorts | 9:16 | 1080×1920 | ~60s worth | 3 min |
| Instagram | Feed (square) | 1:1 | 1080×1080 | 4 GB | 60 min |
| Instagram | Feed (portrait) | 4:5 | 1080×1350 | 4 GB | 60 min |
| Instagram | Stories | 9:16 | 1080×1920 | 4 GB | 60 sec/slide |
| Instagram | Reels | 9:16 | 1080×1920 | 4 GB | 3 min |
| TikTok | Standard | 9:16 | 1080×1920 | 4 GB | 10 min |
| Facebook | Feed video | 16:9 | 1920×1080 | 10 GB | 240 min |
| Facebook | Stories | 9:16 | 1080×1920 | 4 GB | 20 sec |

| LinkedIn | Feed video | 16:9 or 1:1 | 1920×1080 or 1080×1080 | 5 GB | 10 min |
| Pinterest | Standard pin video | 2:3 or 9:16 | 1000×1500 or 1080×1920 | 2 GB | 15 min |
| Snapchat | Story / Spotlight | 9:16 | 1080×1920 | 4 GB | 60 sec / 5 min |
What Happens When You Upload the Wrong Ratio
Each platform handles ratio mismatches differently, and none of them handle it well:
- YouTube adds black bars. Upload a 4:3 video and you get black bars on the sides (pillarboxing). Upload a 9:16 vertical video as a standard upload and you get massive pillarboxing. YouTube never crops or stretches — it always preserves the full frame and adds bars.
- Instagram auto-crops. Upload a 16:9 video to a Reel and Instagram will center-crop it to 9:16, cutting off the left and right edges. You lose nearly half your frame. Instagram also crops 16:9 to 4:5 or 1:1 for feed posts.
- TikTok zooms and crops. A 16:9 horizontal video on TikTok gets zoomed in and center-cropped to 9:16. The result is a blurry, over-cropped mess. Never upload 16:9 to TikTok without reformatting first.
- Facebook adds bars for feed posts but crops for Stories and Reels. The behavior is inconsistent and depends on where the video appears in the app.
- LinkedIn adds bars. Similar to YouTube, LinkedIn pillarboxes or letterboxes rather than cropping. This looks unprofessional in the feed.
How to Repurpose One Video for All Platforms
The most efficient workflow for multi-platform video: shoot in 9:16, then adapt. Here is why:
- Shoot in 9:16 (vertical). This is native for TikTok, Instagram Reels, YouTube Shorts, Facebook Stories, and Snapchat — the five platforms with the most organic reach in 2026.
- Crop for 16:9 (horizontal). Take the top and bottom portions and create a wider frame for YouTube standard videos and Facebook feed. You lose the top and bottom edges, so keep important content centered when shooting.
- Crop for 1:1 (square). Center-crop from your 9:16 footage for LinkedIn and Twitter feed posts. Square video performs well on both platforms.
- Crop for 4:5 (portrait). A slight crop from 9:16 for Instagram feed posts. This ratio takes up more screen space in the feed than 1:1 or 16:9.
Use our Aspect Ratio Calculator to figure out the exact pixel dimensions for each crop, then use our Social Reframe tool or Crop Video tool to do the actual conversion.
The 9:16 Vertical Video Revolution
In 2020, vertical video was still considered "wrong" by most creators. In 2026, it is the dominant format on the platforms with the highest organic reach. The shift happened because:
- Mobile-first consumption — over 80% of social media consumption happens on phones held vertically. 9:16 fills the entire screen. 16:9 fills less than half.
- Algorithm preference — TikTok, Instagram Reels, and YouTube Shorts all prioritize full-screen vertical content in their recommendation algorithms.
- Higher engagement — full-screen content has nowhere to scroll. The viewer is either watching your video or swiping to the next one. This forced attention drives higher completion rates.
When to Use Square (1:1) Video
Square video (1080×1080) is the best compromise format when you need one version for multiple platforms:
- It looks decent on both mobile (fills a good portion of the screen) and desktop (no extreme letterboxing)
- It works natively on Instagram feed, Twitter, LinkedIn, and Facebook feed
- It is easier to add text overlays because the frame is balanced
- It avoids the pillarboxing that makes horizontal video look small on mobile feeds
The tradeoff: 1:1 is not optimal for any single platform. It is the jack-of-all-trades format. For best results on a specific platform, use that platform's native ratio.
How to Calculate the Right Dimensions
Our Aspect Ratio Calculator tells you the target dimensions for any ratio. But it is a math tool — it does not resize or crop video files. For actually changing your video, use these tools in order:
- Calculate the target dimensions with our Aspect Ratio Calculator — enter the target ratio and your desired width (or height) to get the exact pixel dimensions.
- Resize or reframe the video with our Video Resizer for proportional resizing or our Social Reframe tool for platform-specific conversion (16:9 to 9:16 with smart cropping).
- Crop if needed with our Crop Video tool to remove specific edges for a custom ratio.
Platform-Specific Tips for 2026
- YouTube Shorts now allows 3 minutes — still 9:16, still vertical, but longer format means you can repurpose more content.
- Instagram favors 9:16 everywhere — even feed posts are pushing toward vertical. The 1:1 square era is fading. Design for 4:5 or 9:16 for Instagram feed.
- LinkedIn added vertical video — 9:16 video now works natively in the LinkedIn feed and gets higher engagement than horizontal. The professional platform is going casual.
- Twitter/X still prefers 16:9 — horizontal video performs best on Twitter because the timeline is designed for horizontal media. Vertical video works but gets pillarboxed on desktop.
