Facebook Reels have become one of the most powerful ways to reach new audiences, drive engagement, and grow your brand visibility. But even the most creative video can fail if it doesn’t meet Facebook’s official Reels size, format, and resolution requirements.
Using the correct Facebook Reel size and dimensions ensures your content looks sharp, fills the screen properly, and gets prioritized by the algorithm. In this guide, we’ll cover everything from the ideal Facebook Reels size to upload limits, and show you how to optimize your videos for the best results in 2025.
To make your videos stand out on the Reels feed, follow these official Facebook Reels specs and dimensions:
- Aspect Ratio: Recommended 9:16, Minimum 4:5.
- Resolution: Recommended 1080 × 1920 px, Minimum 720 × 1280 px.
- Length: Recommended up to 90 seconds, Minimum 3 seconds. 15–60 sec performs best
- File Size: Recommended ≤ 4 GB. Larger files may fail to upload
- Frame Rate: Recommended 30 fps or higher.
- Format: Recommended MP4 or MOV. Use H.264 codec for best results
- Audio: Recommended AAC, Stereo. Licensed music only
Sticking to these recommended Facebook Reel dimensions prevents unwanted cropping or pixelation, and keeps your video looking professional across all devices. But there are also cases that Facebook still compresses your video after upload even if you follow the Facebook Reels size.
That’s where Aiarty Video Enhancer can help. It enhances and resizes your Facebook reels before posting — preserve every detail, eliminate blur or artifacts, and make your content shine.

Why Correct Facebook Reel Size Is So Important
If your video doesn’t match Facebook’s recommended 9:16 frame, parts of your content may get cut off or show awkward black bars on the sides. Even if the framing looks fine, low-resolution videos can appear blurry after Facebook applies its compression algorithm, which automatically reduces file size to optimize streaming.
Using the correct Facebook Reels size and resolution ensures your video remains sharp, clear, and professional-looking on all devices. Proper sizing not only improves the viewing experience but also helps your content perform better in the algorithm, increasing engagement, watch time, and follower growth.
Simply put, getting your dimensions right = clearer videos + higher visibility + more opportunities to reach your audience.

Facebook Reels Requirements for Ads and Branded Content
If you’re planning to run ads, sponsored posts, or branded partnerships on Facebook Reels, the technical requirements remain largely identical to regular Reels—but the expectations for quality are much higher. Advertisers need to ensure every frame looks polished, since Reels are often viewed full-screen and any flaw becomes noticeable immediately.
Below are the essential specs you should follow:
- Aspect ratio: 9:16 vertical format
- Recommended length: 15 seconds or less for higher retention
- File type: MP4 or MOV using the H.264 codec
- Resolution: 1080 × 1920 px for professional clarity
To keep your branding consistent, make sure your logos, captions, and any on-screen text stay within the center-safe area. Elements placed too close to the edges may be cut off on certain devices or hidden behind interface elements like buttons and overlays.
Facebook Reels Format and Resolution Tips for 2025
Video quality expectations continue rising in 2025, as users scroll through an endless stream of content and instantly skip anything blurry, low-resolution, or poorly edited. To make your Reels stand out, focus on maintaining high visual clarity and smooth motion during both shooting and export.
Follow these best-practice tips to stay ahead:
- Export resolution: 1080p or higher (MP4, H.264 codec)
- Frame rate: 30 fps or 60 fps for smoother motion
- Editing tip: Avoid heavy filters that reduce detail. Also, fix brightness, exposure, and color balance before uploading
Since Reels are fast-paced, you should also aim to capture viewer interest immediately. The first three seconds are crucial. Thus, use a strong hook, eye-catching movement, or a bold headline to stop the scroll and increase watch time.
Resize & Enhance Facebook Reel Quality with Aiarty Video Enhancer
You’ve probably noticed that after uploading a Reel, the video often looks softer or grainier than the original. This is because Facebook automatically compresses videos to reduce file size, which can lead to loss of detail.
To fix this, many creators now pre-optimize their videos using Aiarty Video Enhancer, a professional AI-powered tool designed to restore sharpness, upscale resolution, and remove noise or compression artifacts, and export in Facebook Reels size.
Why Aiarty Video Enhancer Is Perfect for Facebook Reels
- AI Upscaling to 4K: Enhance standard 1080p videos to crystal-clear 4K without losing detail.
- Fix Blurry Footage: Automatically recover edges and clarity lost during compression.
- Reduce Noise and Artifacts: Perfect for low-light or phone-shot videos.
- HDR Enhancement: Expands color depth and contrast, making your Reels more cinematic.
- Crop to Reel size: Directly crop to Facebook reels aspect ratio, or other commen ratios like 1:1, 16:9 etc.
- GPU Acceleration: Optimized for NVIDIA, AMD, and Apple M-series chips for faster processing.
Step 1. Open the Facebook video enhancer
Download Aiarty Video Enhancer and open it. Then drag and drop the videos that are not in the Facebook reel dimensions into the software.
Step 2. Adjust video dimensions for Facebook
On the right panel, open the Upscale drop-down menu. If your video’s resolution is below Facebook’s recommended HD (for example, 720p or SD footage), you can boost it by selecting 2x or 4x upscaling, or set a specific target resolution such as 1920×1080 for 1080p or 3840×2160 for 4K. This ensures your video meets Facebook’s quality standards.
For videos that are already high-resolution (like 1080p or 4K) but need sharper detail or reduced noise, choose the 1x Enhance option to improve clarity without altering the video size.
Step 3. Change the Facebook video size ratio
Next, move to the Edit section. Check the box and click on Adjust Crop. This allows you to set the exact Facebook video aspect ratio for your content, namely 9:16 for Reels. You can also drag the bounding box directly on the video preview to create a custom ratio that perfectly fits your needs.
Step 4. Cut the video length
If your video exceeds Facebook’s length limits for a particular placement, or if you want to feature the most engaging part, use the intuitive progress bar below the video. Simply set your preferred start and end points to trim the video to the ideal length.
Step 5. Fine-tune color
If you're not satisfy with your video colors, you can tick on the Color option, and adjust temperature, tint, contrast, saturation, exposure etc. for better brightness and visual.
Step 6. Export video
Finally, go to Export Settings and select either MOV or MP4, both of which are compatible with Facebook. Then click Export Current to save a single video, or Export Batch to process multiple videos at once.
