Tips for Video Aspect Ratios
- 16:9 is the standard for YouTube, websites, and most widescreen displays.
- 9:16 is ideal for TikTok, Instagram Reels, and YouTube Shorts.
- 1:1 works best for Instagram feed posts and social media thumbnails.
- 4:5 is the recommended format for Instagram portrait posts -- it takes up more screen space.
- 4:3 is the classic TV format, still used in some presentations.
- All processing happens in your browser -- your video never leaves your device.
