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.

Additional Specifications

• Recommended Formats: MP4 or MOV.
• Max Video Length: Up to 240 minutes for feed videos (though shorter is better for engagement).
• Max File Size: Up to 4GB.

The 3:2 aspect ratio is the classic standard for photography, with roots in 35mm film. It remains the native format for the vast majority of DSLR and mirrorless camera sensors today, making it fundamental for photographers to understand.

What is the 3:2 Aspect Ratio?

The 3:2 aspect ratio defines an image where the width is 1.5 times the height. This format became the standard because it was used for 35mm film photography, and that legacy has carried over into the digital age. Most full-frame and APS-C sensors are designed with this ratio.

While resolutions vary by camera, a typical 3:2 image might be 6000x4000 pixels. This ratio also corresponds directly to common print sizes like 6x4 inches.

Why 3:2 is the Photographer's Choice

• Legacy Standard: It's the native format for most high-end digital cameras, meaning you capture the maximum amount of data from your sensor.
• Compositional Flexibility: It provides a pleasing, slightly wide frame that is versatile for both landscape and portrait orientations.
• Print-Friendly: It directly matches popular photo print sizes like 4x6", 6x9", and 8x12", minimizing the need for cropping.

How 3:2 Interacts with Other Formats

When sharing a 3:2 photo on social media, you will often need to crop it. For an Instagram post, you might crop to a 1:1 (square) or 4:5 (portrait) ratio. When displaying it on a 16:9 screen, it will have small black bars on the sides (pillarboxing).

Frequently Asked Questions (FAQ)

What cameras use a 3:2 aspect ratio?

Most DSLR and mirrorless cameras from major brands like Canon, Nikon, Sony, and Fujifilm use a 3:2 aspect ratio for their sensors. In contrast, Micro Four Thirds cameras (from Olympus/OM System and Panasonic) and many smartphones use a 4:3 ratio.

Is 3:2 better than 4:3 for photography?

Neither is inherently "better"; it's a matter of preference. The 3:2 ratio is wider and often considered more "cinematic," while the 4:3 ratio is taller and can feel more balanced for certain compositions. 3:2 is more common in professional photography due to camera hardware standards.

What is the most common 3:2 print size?

The most common and iconic print size for the 3:2 aspect ratio is 4x6 inches. This has been a standard for consumer photo printing for decades.
