Facebook Aspect Ratio Guide
Facebook supports a wide range of video formats across its different placements. Choosing the right aspect ratio is key to capturing audience attention and ensuring your video is displayed correctly.
Feed Videos
For videos that appear in the main Facebook feed, vertical formats perform best as they occupy more screen space on mobile devices.
- Recommended (4:5): A portrait aspect ratio like 4:5 is ideal for mobile viewing. A common resolution is 1080x1350 pixels.
- Square (1:1): Square videos (e.g., 1080x1080 pixels) are also highly effective and versatile.
- Landscape (16:9): While supported, horizontal videos take up less screen space and may be less engaging on mobile.
Facebook Stories & Reels (9:16)
Like Instagram, Facebook Stories and Reels are designed for a full-screen, vertical experience. The optimal aspect ratio is 9:16 with a resolution of 1080x1920 pixels.

Source: Meta Business Help Center - Video Specs.The 9:16 aspect ratio is the undisputed king of vertical video. It's the standard format for mobile-first platforms like TikTok, Instagram Reels, and YouTube Shorts, designed to fill the entire screen of a smartphone held upright.
What is the 9:16 Aspect Ratio?
The 9:16 aspect ratio is the vertical counterpart to the 16:9 widescreen format. For every 9 units of width, there are 16 units of height. This tall, narrow format is optimized for how people naturally hold their phones, making it perfect for short-form, attention-grabbing content.
The standard resolution for a 9:16 video is 1080x1920 pixels.
Why 9:16 is Essential for Social Media
- Mobile-First Dominance: It's the native format for TikTok, Instagram Reels, and YouTube Shorts.
- Maximum Screen Real Estate: It fills the entire phone screen, creating an immersive experience and minimizing distractions.
- Higher Engagement: By taking up more space in a user's feed, vertical video is more likely to capture and hold their attention compared to horizontal or square formats.
How 9:16 Interacts with Widescreen
When you display a 9:16 video on a horizontal 16:9 screen (like a TV or a standard YouTube player), you will see large black bars on the left and right sides. This effect is called pillarboxing.

Should I use 9:16 for a regular YouTube video?
No, unless you are specifically uploading a YouTube Short. For standard, long-form YouTube videos, you should always use the 16:9 horizontal aspect ratio to avoid large black bars on desktop and TV screens.
