Trying to nail down the right video dimensions for Facebook can feel like a moving target. Here’s a good rule of thumb I always start with: a 4:5 aspect ratio (1080×1350 pixels) works beautifully for most feed placements, but you'll absolutely need a full-screen 9:16 (1080×1920 pixels) for your Reels and Stories.
Getting these specs right from the beginning is the difference between a video that looks polished and one that gets awkwardly cropped or looks fuzzy.

WordpressIf you're a creator or social media manager, you know that time is everything. You can't be hunting for the latest video specs every time you post. That's why I've put together this quick reference guide with all the essential numbers you need for Facebook's key video spots in 2026.
Think of this as your cheat sheet for getting it right, every time.
As you can see, the format really depends on where the video will live. Vertical is king for immersive experiences like Reels, while taller or square formats are perfect for grabbing attention as people scroll their feed.
I've boiled down the most common placements into a simple table. Bookmark this page, print it out, or just keep it handy. From the main Feed to Carousel ads, each format has its own sweet spot for making the biggest impact.
After years of managing video content, I can tell you the single biggest mistake people make is trying to use one video size everywhere. A landscape 16:9 video, for example, looks tiny and gets lost in a vertical-first placement like Stories or Reels.
Here’s a quick breakdown of what you need to know.
| Placement | Recommended Resolution (Pixels) | Aspect Ratio | Max Duration | Max File Size |
|---|---|---|---|---|
| Feed Video | 1080 x 1350 | 4:5 | 240 Minutes | 4 GB |
| Reels & Stories | 1080 x 1920 | 9:16 | 90 Seconds | 4 GB |
| Carousel Video | 1080 x 1080 | 1:1 | 240 Minutes | 4 GB |
| In-Stream Ads | 1920 x 1080 | 16:9 | 15 Seconds | 4 GB |
Sticking to these numbers is your best bet for making sure your videos look sharp and professional. When you use the dimensions Facebook prefers, you avoid weird cropping, compression issues, and black bars, which sets you up for much better performance.
Now, let's dig a little deeper into the specific requirements and best practices for each of these placements.
Getting the numbers right for your Facebook videos is more than just a technical chore. Honestly, it's one of the most important things you can do. You could have the most compelling video in the world, but if it looks weird on someone's phone, they're just going to scroll right by.
Think about it. When you upload a video with the wrong specs, Facebook has to make it fit. That often means it gets butchered by awkward crops, cutting off your face or that crucial line of text. Even worse, it might get slapped with those ugly black bars, instantly screaming "this content wasn't made for you." That jarring experience is a scroll-stopper, but not in a good way.
On a crowded mobile feed, your goal is to own as much of the screen as you possibly can. Attention is the currency, and a bigger video gets more of it. A video in a vertical 4:5 aspect ratio, for instance, takes up significantly more space on a phone than a traditional widescreen 16:9 video.
Taking up more visual space has a direct impact on your results:
When a video is sized correctly, it feels native to the platform. It blends in perfectly with how people are already consuming content, creating a smooth, frictionless experience that builds subconscious trust with your audience.
At the end of the day, Facebook’s algorithm wants to show people content they’ll enjoy. Uploading a video with the right dimensions is a clear signal that you’ve created a quality experience designed specifically for the platform and its users. The algorithm rewards this with better organic reach.
A perfect example is a 9:16 video for Stories or Reels. It creates that all-in, full-screen experience people expect in that format. If you try to shoehorn a tiny landscape video in there, you disrupt the flow and it just looks lazy. Getting these placement-specific details right is a huge part of a successful Facebook content strategy for businesses.
Ultimately, choosing the right video dimensions isn't just about following rules—it's a strategic move. It ensures your message lands, your visuals pop, and your hard work gets the engagement and reach it deserves.
The Facebook Feed is a crowded place. Think about it—your video is up against posts from friends, family, and every other brand someone follows. To even stand a chance, your video dimensions have to be perfect for the environment. And right now, that environment is overwhelmingly mobile.
For the modern Facebook feed, forget everything you learned about traditional video. The format that consistently gets the best results is a 4:5 aspect ratio. It’s a vertical format that takes up a huge chunk of a smartphone screen, making it much harder to just scroll past. This is how you stop the thumb.
When you’re creating for the feed, your goal should be to fill as much screen real estate as possible. That’s why 1080×1350 pixels, which gives you that 4:5 ratio, has become the go-to. It just works. We’ve seen this trend grow as fully vertical 9:16 videos (like those for Stories and Reels) started dominating.
The numbers don't lie. We’ve seen vertical videos hit 1.77% engagement on smaller accounts, while square videos on the same accounts only managed 0.8%. That’s a massive difference driven by a simple change in shape. If you want to dive deeper into the data, you can see how video statistics influence strategy.
While 4:5 is what I always recommend first, Facebook does support other formats. It’s worth knowing how they’ll look to your audience.
Square (1:1): A video at 1080×1080 pixels is a solid, safe bet. It performs well on both mobile and desktop and is a great option if you’re creating assets for a carousel post.
Landscape (16:9): This is your classic widescreen format, usually 1920×1080 pixels. It’s still supported, but on a mobile phone, it looks tiny. It gets squeezed between big letterboxes, making it easy to ignore.
Pro Tip: Always create your videos assuming the sound will be off. Most people are scrolling in public or don't want audio blasting. Use captions or clear on-screen text to make sure your message lands, no sound required.
Getting the shape right is half the battle; the other half is making sure the file itself is optimized. Uploading a video with the right technical settings helps Facebook process it better, which means less ugly compression and a crisper final product for your viewers.
Here’s a quick cheat sheet for the technical details you should aim for:
| Specification | Recommendation | Why It Matters |
|---|---|---|
| File Format | MP4 or MOV | These are the most reliable and widely accepted formats for video on the web. |
| Video Codec | H.264 | This codec gives you great video quality without making the file size enormous. |
| Frame Rate | 30 FPS (Frames Per Second) | Stick to 30 FPS for smooth motion that doesn't create a file that's unnecessarily large. |
| Max File Size | 4 GB | This is a generous limit, more than enough for most high-quality feed videos. |
| Max Duration | 240 Minutes | You can upload a four-hour video, but please don't. Keep it short—under 2 minutes is usually the sweet spot for engagement. |
Nailing these specs ensures your video looks as good on Facebook as it did on your computer. Once your file is ready to go, the final step is getting it uploaded. If you need a quick rundown on that part of the process, our guide on how to share a video on Facebook walks you through it.
While the Feed is still a major player, the real action and growth on Facebook are happening in Stories and Reels. These formats are all about full-screen, immersive experiences, which means your video dimensions need a totally different game plan. To make content that feels native and stops the scroll, you have to go vertical with a 9:16 aspect ratio.
This means your videos should be 1080×1920 pixels. If you upload anything else, Facebook will either crop it awkwardly or slap ugly black bars on it—a dead giveaway that your video wasn't made for this format. For Stories and Reels, a full-screen video isn't just a suggestion; it's a must.
Even though they share the same full-screen dimensions, it's a mistake to treat Facebook Stories and Reels as identical. They serve different purposes and have their own time limits you need to respect. Think of Stories as your casual, behind-the-scenes moments, while Reels are your polished, entertaining clips designed to go viral.
Here's a quick breakdown of their key technical specs:
For both placements, you get a generous max file size of 4 GB, and your best bets for file formats are MP4 or MOV. This gives you plenty of flexibility to upload high-quality video. For a deeper dive into this format, check out our complete guide on vertical video dimensions for creators.
Okay, so you’ve created a perfect 1080×1920 video. You’re not done yet. The single most common mistake creators make is forgetting about the "safe zone." Facebook’s interface—your profile name, the like/comment buttons, and captions—will cover parts of your video.
This is critical: The top and bottom sections of your 9:16 video are danger zones. Any text, logos, or important visuals placed there will likely be blocked by the app's user interface.
To keep your content clear and professional, stick to these guidelines:
By keeping your essential elements within this central area, you guarantee your message gets seen without any obstructions. If you're also posting on Instagram, you'll find that many of the best Instagram Reels tips about safe zones and viewer engagement apply directly to Facebook Reels, too.
When you're putting money behind a Facebook campaign, you need every penny to work for you. Unlike your regular organic posts, video ads show up all over the place—from the main feed to interrupting another video mid-stream. Each of these ad placements has its own set of rules, and getting them right is crucial for your ad's performance.
If you ignore the specs, you're risking rejected ads or, even worse, blowing your budget on videos that look cropped and unprofessional. The reality is that a single video often needs to be tweaked and resized to look great across Facebook's entire ad network.
Let's start with the two most common spots you'll see video ads. In-feed ads are the sponsored posts that pop up while you're scrolling, while in-stream ads act like mini TV commercials that play during other videos.
In-Feed Video Ads: For these, you’ll want to use a vertical 4:5 aspect ratio with a 1080×1350 pixel resolution. This format takes up the most screen real estate on a phone, which is where most people will see your ad.
In-Stream Video Ads: Since these ads play inside other landscape videos, they need to match that format. Go with a standard 16:9 aspect ratio at 1920×1080 pixels. Just remember, these are often skippable, so make your point quickly.
For both placements, keep your file size under 4 GB and stick to MP4 or MOV formats. And always assume the sound is off—use clear on-screen text or captions to get your message across.
Your ads can also reach people in Facebook Marketplace and on search results pages. These are fantastic spots for targeting users who are actively looking to buy something, so a polished video is non-negotiable.
When you need a versatile ad that works almost anywhere, a 1:1 square aspect ratio (1080×1080 pixels) is your best friend. This is especially true for placements like Marketplace, where it ensures your video looks clean whether it’s in a grid or next to other product listings.
The square format just feels balanced and looks good on any device without awkward cropping. It’s a safe, reliable choice when you need one ad creative to pull double or triple duty.
To keep your campaigns running smoothly and avoid any frustrating rejections from Facebook, it helps to follow a few core technical rules. Think of this as your pre-flight checklist before launching an ad.
| Specification | Recommendation | Why It's Important |
|---|---|---|
| Resolution | Minimum 1080×1080 pixels | Always upload in at least 1080p. This gives your video a fighting chance against Facebook's compression, keeping it looking crisp. |
| Video Length | 1 second to 240 minutes | You can upload a long video, but ads under 15 seconds almost always perform better. Get in, deliver your message, and get out. |
| Headline Text | 25-40 characters | Keep your headline short and sweet so it doesn't get cut off, particularly on smaller mobile screens. |
| Primary Text | Around 125 characters | This is your main caption. State your point clearly and up front, because most people won't click to "see more." |
Once you get a handle on the specific video dimensions Facebook ads require, you put your campaigns in a much better position to succeed. A properly formatted video simply looks more professional and creates a better experience for the viewer, which ultimately leads to more engagement and a stronger return on your investment.
When it comes to e-commerce and storytelling on Facebook, Carousel and Collection ads are absolute powerhouses. They let you pack multiple products or story beats into one interactive post, inviting people to swipe and explore. Getting the video specs right is crucial for making that experience feel seamless, not clunky.
The single most important rule? Consistency. While Facebook is flexible, mixing and matching aspect ratios between your carousel cards creates a jarring experience. We always recommend sticking to a 1:1 square aspect ratio (1080×1080 pixels) for every single video. It just looks clean, professional, and keeps the user focused on your content.
On the technical side, these ads have a few specific rules you need to follow. They’re built to show off a lot of content, so there are limits on the number of videos and their file sizes.
This setup gives you the freedom to tell a story across several clips or showcase an entire product line, with each card getting its own unique link.
Beyond the numbers, how you use your carousel videos is what really drives results. You want to create a flow that pulls someone from the first card all the way to the last. Think about showing a product from different angles, or feature a variety of people using it in unique situations.
Pro Tip: Try creating a "panorama" effect where the action in one video visually flows into the next. It’s a clever little trick that piques curiosity and makes people want to swipe to the end just to see the whole picture.
Ultimately, a good carousel feels like a single, cohesive experience. Aiming for 2-10 cards at a 1:1 or 4:5 ratio, each under 4 GB, will ensure everything loads smoothly. With so many people watching video on Facebook, digging into your analytics is key to refining your approach and hitting those impressive ad view-through rates, which can reach up to 30%.
To see how these formats fit with other ad types, you can discover more insights about Facebook video ad sizes and build a more well-rounded campaign strategy.
Getting your video dimensions Facebook recommends is the first step, but it’s not the whole story. If you’ve ever uploaded a video that looked sharp on your computer only to see it turn fuzzy on Facebook, you’ve met the platform’s aggressive compression algorithm. To beat it, you need to dive into the technical settings.
Think of it this way: Facebook is going to shrink your video file no matter what. So, to get a great-looking result, you have to give it the best possible source file to work with. The golden rule is simple: always upload the highest resolution and quality file you can. A video that starts as a crisp 1080p or 4K file will look infinitely better after compression than one that started at 720p.
Bitrate is all about how much data is packed into each second of your video. More data usually means better quality, but also a much larger file. While Facebook doesn't give us official bitrate targets, we know it compresses everything heavily.
Your secret weapon here is exporting with a variable bitrate (VBR). Instead of using the same amount of data for every second (a constant bitrate), VBR intelligently allocates more data to complex, high-motion scenes and less to simple, static ones. It’s a smarter, more efficient way to maintain quality where it counts most.
These settings directly affect how smooth your video looks. While it’s tempting to go with the highest numbers your camera can produce, that's often overkill for Facebook.
Frame Rate: For the vast majority of content, 30 FPS (frames per second) is the standard for Facebook. It delivers smooth motion that looks natural to the eye without bloating your file size.
Scan Type: Always, always export using progressive scan (p)—think 1080p, not 1080i. Interlaced scan (i) was designed for old-school TVs and can create nasty visual glitches like jagged lines when compressed for the web. Thankfully, most modern editing software defaults to progressive, so you usually just need to double-check this setting.
Let’s be honest: terrible audio will make someone scroll past your video faster than blurry visuals. You put a lot of work into your content, so don't let muffled or tinny sound ruin the experience for your audience.
To make sure your audio sounds as clean as possible after uploading, stick to these settings during your export:

Paying attention to these specs ensures your final video looks and sounds as polished as you intended.
Even when you think you've got all the specs down, a few common questions always seem to pop up. We get it. Getting the small details right is often the difference between a professional-looking post and one that feels off.
Let's clear up some of the most frequent sticking points so you can post your videos with confidence.
If you only have the time or budget to create one version of a video, your safest bet is the 4:5 aspect ratio (1080×1350 pixels). This format is a fantastic workhorse for the main Facebook feed.
Why? It takes up a ton of vertical space on mobile screens, grabbing more attention than a standard widescreen video. While a vertical 9:16 video is absolutely essential for a full-screen experience in Stories and Reels, the 4:5 dimension won't get awkwardly cropped in most other places, making it the most versatile choice for general use.
This is a classic problem, and the culprit is almost always Facebook’s aggressive compression. To make sure videos load quickly for everyone (even on slow connections), Facebook shrinks your file size after you upload it, which can unfortunately lead to a drop in quality.
The best way to fight this is to give Facebook a high-quality file to begin with. Always export and upload your video in the highest resolution possible—at least 1080p—with a high bitrate. Think of it this way: the better the file you give the algorithm, the more detail it has to work with.
Starting with a crisp source file in the recommended MP4 format with an H.264 codec will result in a much cleaner, sharper video for your audience, even after compression.
Yes, you absolutely can, and you should! This is a huge time-saver. Both Facebook Reels and Instagram Reels are built for the exact same specs: a 9:16 aspect ratio (1080×1920 pixels) with a maximum length of 90 seconds.
This perfect alignment makes cross-posting a breeze. You can create one polished vertical video and share it natively on both platforms without worrying about re-editing or weird formatting issues.
