Core video specs you need to understand
Before looking at video dimensions for each platform, it’s important to grasp some key terms that affect how videos display and perform:
Resolution vs aspect ratio
- Resolution is the pixel dimensions (e.g., 1080 x 1920) and defines clarity.
- Aspect ratio describes the shape of your video (e.g., 16:9).
- Vertical formats like 9:16 are crucial for mobile-first content. They dominate platforms such as Tiktok as well as Instagram reels.
Video formats
- MP4 with H.265 codec is the most universally supported video format and delivers efficient compression without a lot of quality being lost.
- Make sure you avoid outdated formats like WMV or AVI – they can lead to upload errors.
Frame rate (FPS)
- Standard 24-60 fpsis accepted across major social media platforms.
- Higher frame rates can create smoother motion. However this doesn’t necessarily translate to better engagement.
File size and bitrate
- Larger file sizes mean better quality, but be aware of platform limits.
- Bitrate impacts file size and quality. If it’s too low it can cause pixelation, and if it’s too high it may get rejected.
Instagram video sizes
There are various sizes to be aware of when it comes to videos on Instagram.
Instagram reels
- Resolution: 1080 x 1920 (vertical)
- Aspect ratio: 9:16
- Max length: 20 minutes
- Max file size: 4GB
Instagram reels are the made video format on the platform that drives engagement. Remember to avoid putting critical text near the top or bottom as it may be covered when posted.
Instagram stories
- Resolution: 1080 x 1920
- Aspect ratio: 9:16
- Max length: 60 seconds per story
Brand messages should be concise and front-loaded. Stories benefit from full-screen vertical videos rather than horizontal.
Instagram feed videos
- Square: 1080 x 1090 (1:1)
- Portrait: 1080 x 1350 (4:5)
- Landscape: 1920 x 1080 (16:9)
Portrait videos perform much better in an Instagram feed as they take up more screen space and blend in well with other types of content.
TikTok and YouTube shorts
Both TikTok and YouTube Shorts are mobile-first platforms, meaning vertical content is preferred and looks more professional.
TikTok videos
- Resolution: 1080 x 1920
- Aspect ratio: 9:16
- Max length: 60 minutes when uploaded or 10 minutes when recorded directly through the app
- Max file size: 72MB Android or 287.6MB iOS
Video content on TikTok performs best when the first few seconds are strong.
YouTube Shorts
- Resolution: 1080 x 1920
- Aspect ratio: 9:16
- Max length: 3 minutes
- Max file size: 256GB but for faster processing it’s recommended to keep it under 500MB
Quick hooks and punchy edits are what these short vertical clips thrive on.
Facebook, LinkedIn, Pinterest, and X (Twitter)
Each social media platform has its own set of video sizes to be aware of. For example, Facebook videos benefit from different aspect ratios based on the format. X (Twitter) still supports landscape and square videos, LinkedIn is a more versatile platform and can handle both square and landscape formats, and Pinterest allows for a range of aspect ratios but vertical formats maximize space.
Here are the most important video sizes to know about:
| Platform | Aspect Ratio | Resolution | Max Length | Max File Size |
| Facebook Feed | 16:9/4:5/1:1 | 1280 x 720 / 1080 x 1350 / 1080 x 1080 | 241 minutes | 4GB |
| Facebook Reels/Stories | 9:16 | 1080 x 1920 | No limit | 4GB |
| X (Twitter) feed | 16:9/1:1/9:16 | 1280 x 720 / 1080 x 1080 / 1080 x 1920 | 140 seconds | 512MB |
| LinkedIn feed | 16:9/1:1 | 1280 x 720 / 1080 x 1080 | 10 minutes | 5GB |
| Pinterest (video pins) | 2:3/9:16 | 1000 x 1500 / 1080 x 1920 | 15 minutes | 2GB |
Cross-platform workflow
One of the biggest problems that content creators come across is resizing their videos across multiple social media platforms. The solution to this is strategic planning.
- Shoot in the highest quality with plenty of headroom.
- Frame your subject along a “safe zone” that works with different crops.
- Use tools like Premiere Pro for detailed control or CapCut for quick edits.
- Always test the output before scheduling your content.
- Use DropBox or WeTransfer to move high-quality footage between devices without losing resolution.
If you’re using mobile-first platforms like TikTok or Instagram, use a vertical 9:16 file. For YouTube long form, a landscape 16:9 file is the best option.
Troubleshooting and optimizing social media video sizes
Even with the right video dimension aspects, brands can still come across problems.
- “File too large” errors: Reduce the bitrate or trim the duration. Re-export using MP4 (H.264).
- Cropping and UI overlay issues: In future, leave “safe zones” around logos and text so they’re not cut off. This is a common problem on TikTok and Instagram.
- Unsupported format message: Convert files from MOV to MP4 before uploading.
Context matters just as much as the perfect video dimensions. Although 1080p is recommended for most platforms, higher resolutions such as 4K help future-proof content. In terms of duration:
- TikTok/TikTok ads: Attract attention in the first few seconds to keep people watching longer.
- Reels/Shorts: Engagement usually drops after 30 seconds.
- LinkedIn: Slightly longer, value-driven stories perform best due to the professional setting of the platform.
Final thoughts: Finding the right size for consistency
Getting social media video sizes correct is a key part of modern video marketing. A consistent approach ensures your video content loads quickly, looks attractive, and resonates with audiences – regardless of what platform they’re using. Recommended aspect ratios and maximum lengths change regularly, so it’s important to keep on top of these changes by using official platform channels.
