Aspect Ratios for Video: Platform Guide and Cropping Strategy
Each social platform and device favors different aspect ratios. Shooting and cropping strategically ensures your video fills the screen everywhere it appears.
Key Takeaways
- Film in 16:9 at the highest resolution available, then crop for other ratios in post-production.
- Cropping 16:9 to 9:16 removes 68% of the frame.
- Letterboxing adds black bars to maintain the original ratio.
- Always use square pixels (1:1 PAR).
- Cropping is almost always preferred for social media.

Common Aspect Ratios
| Ratio | Pixels | Usage |
|---|---|---|
| 16:9 | 1920x1080 | YouTube, TV, desktop web |
| 9:16 | 1080x1920 | TikTok, Reels, Shorts |
| 1:1 | 1080x1080 | Instagram feed, Facebook |
| 4:5 | 1080x1350 | Instagram feed (max height) |
| 4:3 | 1440x1080 | Legacy TV, presentations |
| 21:9 | 2560x1080 | Cinematic, ultrawide |
Shooting for Multiple Platforms
Film in 16:9 at the highest resolution available, then crop for other ratios in post-production. Frame your subject in the center third of the frame β this is the 'safe zone' that remains visible in any crop.
Cropping Strategy
Vertical from Horizontal
Cropping 16:9 to 9:16 removes 68% of the frame. Ensure key content (faces, text, action) stays centered. Auto-reframe tools in Premiere Pro and DaVinci Resolve use AI to track subjects.
Square from Horizontal
1:1 crop from 16:9 removes the left and right edges. This works well when the subject is centered but fails for wide establishing shots.
Letterboxing vs Cropping
Letterboxing adds black bars to maintain the original ratio. While it preserves the full frame, it wastes screen space and looks unprofessional on mobile feeds. Cropping is almost always preferred for social media.
Pixel Aspect Ratio
Always use square pixels (1:1 PAR). Non-square pixels are a legacy artifact from analog TV and cause distortion in modern players.
