To begin with, Facebook recommends using square (1:1) or vertical (4:5, 2:3, 9:16) aspect ratios, which offer the best compatibility. While most file types are supported, always upload the highest-resolution video available for quality. Facebook also suggests using H.264 compression, square pixels, a fixed frame rate, progressive scan, and stereo AAC audio compression at 128+ kbps.
Additionally, shorter videos tend to perform better and are more likely to be watched to completion. Ensure your videos work well with or without sound for wider accessibility.
Now, let’s take the different video ad formats one by one and look at their Facebook ad video size.
Facebook Video Ad Sizes & Dimensions: A Complete Guide For 2025
When it comes to creating successful Facebook ads, using the correct Facebook video ad dimensions is crucial. Your ad’s performance largely depends on how well your video fits within the platform’s visual parameters. If your content doesn’t match the recommended specs, it may appear cropped, distorted, or simply fail to grab attention — which means missed opportunities.
To help you maximize the impact of your video content, we’ve compiled the most up-to-date information on Facebook video ad dimensions for all current ad formats. From Facebook Timeline video ads to Slideshow Video ads, we’ll guide you through the specifications needed to ensure your campaigns look polished, professional, and compelling.
Facebook Timeline Video Ads
Facebook Timeline video ads are the most widely used video format on the platform. They appear directly in users’ news feeds as they scroll, making them highly visible and ideal for capturing attention during casual browsing. A video ad appears in users’ news feeds seamlessly alongside organic posts, making it feel less intrusive yet still impactful. These ads are best used for product promotions, brand awareness, announcements, or retargeting campaigns.
Recommended Specs:
- Video Dimensions: At least 1280 x 720 pixels (HD)
High-resolution videos ensure clarity and professionalism. Larger dimensions result in better quality visuals on both desktop and mobile devices. - Minimum Dimensions: 600 x 315 (landscape) or 600 x 600 (square)
These are the smallest acceptable sizes, but using the bare minimum may lead to lower quality. Only use these if you’re working with older or compressed assets. - Aspect Ratios: 16:9 (landscape), 1:1 (square)
Landscape works well on desktops, while square is better suited for mobile, offering a balanced experience across devices. - Max File Size: 4GB

FAQs
Q1: What are the best dimensions for Facebook video ads?
The best dimensions for Facebook video ad dimensions are at least 1280 x 720 pixels. This resolution offers high-definition quality, which ensures your video looks sharp and professional on all screen sizes. Facebook supports a variety of formats, but the most commonly recommended aspect ratios include:
- 1:1 (square): Perfect for both desktop and mobile. This format takes up more space on the screen and increases visibility in the news feed.
- 9:16 (vertical): Optimized for mobile-first viewing. This full-screen format matches the way users naturally hold their phones, offering an immersive experience.
Using these dimensions not only enhances your ad’s appearance but also helps improve engagement rates and ad performance.
Q2: Which format works best for mobile users?
For mobile users, vertical video formats like 4:5 and 9:16 are the most effective. Since most Facebook users access the platform through their smartphones, designing for mobile-first is no longer optional; it’s essential.
- 9:16: This format occupies the entire screen vertically, making it ideal for Facebook Stories, Reels, and mobile news feed placements.
- 4:5: Slightly less tall than 9:16 but still highly mobile-friendly. It works well for in-feed videos while offering more space for accompanying text.
These mobile-optimized formats align with how users naturally interact with their devices, increasing the chances that your video ad will be watched all the way through.
Q3: Can I use captions in Facebook video ads?
Yes, captions can and should be used in Facebook video ads, especially since many users scroll through their feeds with the sound turned off. However, there’s an important detail to remember:
- For ad formats like Facebook Stories, captions must be hardcoded (also known as burned-in or embedded) into the video file. This means the text must appear visually in the video itself, as Facebook Stories do not support separate subtitle tracks.
- For other formats like news feed or video feed ads, you can upload captions (SRT files) separately using Facebook’s ad tools.
Adding captions not only makes your content accessible to a broader audience (including the hearing impaired) but also boosts watch time and message retention.
