TLDR: YouTube wants 1920×1080 (16:9) for regular videos and 1080×1920 (9:16) for Shorts. TikTok wants 1080×1920 (9:16). Instagram Reels want 1080×1920 (9:16), while feed posts work best at 1080×1080 (1:1) or 1080×1350 (4:5). LinkedIn takes 1920×1080 (16:9). Twitter prefers 1280×720 (16:9). Use VidStudio's resize tool with platform presets to get the exact specs for each platform.
Why Specs Matter
Every platform has recommended video dimensions, file sizes, and formats. Upload the right specs and your video displays perfectly. Upload the wrong specs and the platform might add black bars, auto-crop awkwardly, compress aggressively, or reject your file entirely.
These specs change occasionally as platforms update their apps. This guide reflects current recommendations as of 2026.
YouTube
Standard Videos
- Dimensions: 1920×1080 (Full HD) or 3840×2160 (4K)
- Aspect ratio: 16:9
- Frame rate: 24, 25, 30, 48, 50, or 60 fps
- Format: MP4 with H.264 video and AAC audio
- Max file size: 256GB
- Max length: 12 hours (or 128GB, whichever comes first)
YouTube accepts nearly any resolution from 240p up to 8K. Widescreen 16:9 fills the player. Other ratios get letterboxed with black bars.
YouTube Shorts
- Dimensions: 1080×1920
- Aspect ratio: 9:16 (vertical)
- Max length: 60 seconds
Shorts require vertical video. Horizontal uploads won't appear in the Shorts feed.
TikTok
- Dimensions: 1080×1920 (minimum 720×1280)
- Aspect ratio: 9:16 (vertical)
- Frame rate: 24-60 fps (30 fps recommended)
- Format: MP4 or MOV
- Max file size: 287MB (mobile), 10GB (desktop upload)
- Max length: 10 minutes
TikTok is entirely vertical. Horizontal videos technically upload but display tiny with massive black bars and look completely out of place in the feed.
Reels
- Dimensions: 1080×1920
- Aspect ratio: 9:16 (vertical)
- Frame rate: 30 fps
- Format: MP4
- Max file size: 4GB
- Max length: 90 seconds
Stories
- Dimensions: 1080×1920
- Aspect ratio: 9:16 (vertical)
- Max length: 60 seconds per story (auto-splits longer videos)
Feed Posts
- Dimensions: 1080×1080 (square) or 1080×1350 (portrait 4:5)
- Aspect ratio: 1:1 or 4:5
- Frame rate: 30 fps
- Max file size: 4GB
- Max length: 60 minutes
For feed posts, 4:5 takes up more screen space than square while scrolling. Landscape videos work but get cropped in the grid view.
- Dimensions: 1920×1080 (landscape) or 1080×1080 (square)
- Aspect ratio: 16:9 or 1:1
- Frame rate: 30 fps
- Format: MP4
- Max file size: 5GB
- Max length: 10 minutes (up to 15 minutes for some accounts)
LinkedIn supports both landscape and square. Square takes up more feed space on mobile. Landscape works well for presentation-style content.
Twitter/X
- Dimensions: 1280×720 (landscape) or 720×720 (square)
- Aspect ratio: 16:9 or 1:1
- Frame rate: 30-60 fps
- Format: MP4
- Max file size: 512MB
- Max length: 2 minutes 20 seconds (10 minutes for some accounts)
Twitter auto-crops video thumbnails in the feed to roughly 16:9 regardless of original dimensions. Vertical videos display with heavy letterboxing.
Feed Videos
- Dimensions: 1280×720 (landscape) or 1080×1080 (square)
- Aspect ratio: 16:9 or 1:1
- Frame rate: 30 fps
- Format: MP4 or MOV
- Max file size: 10GB
- Max length: 240 minutes
Reels and Stories
- Dimensions: 1080×1920
- Aspect ratio: 9:16 (vertical)
Facebook is flexible with formats. The feed accepts most ratios, but square and landscape perform best.

Format and Codec Tips
MP4 with H.264 is the universal standard. Every platform accepts it, every device plays it, and it offers good compression. When in doubt, export to H.264 MP4.
H.265 (HEVC) offers better compression but isn't universally supported. Some platforms accept it, but H.264 is safer.
AAC audio is the standard for web video. Use 128kbps or higher for clean sound.
30 fps is fine for most content. Use 60 fps for gaming, sports, or anything with fast motion.
File Size Considerations
Even when platforms accept large files, smaller uploads are faster and more reliable. If your video is within specs but still huge, consider compressing it before uploading.
Target sizes for smooth uploads:
- Under 100MB for TikTok (mobile upload)
- Under 500MB for Twitter
- Under 1GB for most other platforms
Creating for Multiple Platforms
If you're posting the same content everywhere, you'll need different versions. A few strategies:
Record in 4K with centered framing. Start with high resolution and keep your subject in the middle. This gives you room to crop for different aspect ratios while maintaining quality.
Create a master version first. Edit your full video in its original ratio, then export crops for each platform.
Use presets. VidStudio's resize tool has presets for every major platform. Pick your target and the dimensions are set automatically.
Frequently Asked Questions
What if my video is slightly off from the recommended specs?
Small differences usually don't matter. 1920×1080 and 1920×1088 look identical. But getting the aspect ratio right (16:9, 9:16, etc.) matters. Wrong ratios cause letterboxing or weird cropping.
Does higher resolution always mean better quality?
Not necessarily. A well-compressed 1080p video can look better than a poorly-compressed 4K video. Resolution matters, but bitrate and encoding quality matter more.
Why do platforms compress my video after upload?
Platforms re-encode everything to their own specs for consistent streaming. Upload higher quality than you need to account for this compression. Your 1080p upload might display at lower bitrate than you exported.
Can I use the same video everywhere?
You can, but it won't look native anywhere. A 16:9 video on TikTok shows tiny. A 9:16 video on YouTube gets side bars. Creating platform-specific versions takes more time but performs better.
