As vertical video continues to dominate mobile platforms like Instagram, TikTok, and Snapchat, understanding the best aspect ratio for these videos is essential. The aspect ratio refers to the relationship between the width and height of your video. Choosing the right one can significantly impact how your content is displayed and engaged with on different platforms. 

The Standard: 9:16 

The most common aspect ratio for vertical video is 9:16. This ratio fills the entire screen on mobile devices, making it the optimal choice for immersive viewing. Whether you’re creating Instagram Stories, YouTube Shorts, or TikTok videos, the 9:16 format ensures that your content fits perfectly without black bars or cropping issues. It’s the default aspect ratio for most vertical video formats across social platforms, maximizing your video’s potential for engagement. 

When to Use 4:5 

While 9:16 is the go-to for vertical video, 4:5 is another useful aspect ratio, especially for certain platforms like Facebook and Instagram feeds. It’s slightly less tall but still vertical, offering a better fit for in-feed videos that aim to grab attention while users scroll. A 4:5 aspect ratio is ideal for those who want their video to take up most of the screen without being as elongated as 9:16. 

Other Aspect Ratios to Consider 

  • 1:1 (Square): Although not technically vertical, the 1:1 aspect ratio can work well for mobile-first platforms. It’s commonly used in Instagram feeds and Facebook ads, offering versatility across different placements.
  • 2:3: Less common but sometimes used in portrait-style photography and videos, this ratio offers a slightly wider option while remaining vertical. It’s more suitable for specialized apps or content that requires a more refined look. 

Which Aspect Ratio Should You Choose? 

When deciding the best aspect ratio for vertical videos, consider your platform and audience. If you’re creating content for social media, 9:16 is the best choice for full-screen engagement. However, if you’re focusing on in-feed videos or want more versatility across platforms, 4:5 or 1:1 might be better suited. 

Ultimately, choosing the right aspect ratio comes down to optimizing your content for mobile-first consumption. As the popularity of vertical video continues to grow, ensuring that your video format fits seamlessly with your audience’s viewing habits is key to maximizing engagement.
