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.
