Quick Start Guide
- Reels & Stories: Use a 9:16 aspect ratio (1080x1920 pixels). This is the mandatory full-screen vertical format.
- Feed (Portrait): Use a 4:5 aspect ratio (1080x1350 pixels). This maximizes screen space in the main feed, increasing view duration.
- Feed (Square): Use a 1:1 aspect ratio (1080x1080 pixels). Reserve this for carousels or maintaining a specific grid aesthetic.
- Observe Safe Zones: Keep critical elements (text, logos) away from the edges to avoid being obscured by UI overlays. For Reels, leave ~14% clear at the top and ~25% at the bottom.
- Export Settings: Use MP4 format, H.264 codec, AAC audio, and a video bitrate of 3.5 Mbps for 1080p footage to prevent quality degradation.
Why Your Instagram Video Aspect Ratio Matters
Uploading a video with the wrong aspect ratio cedes control to Instagram's automated compression and cropping algorithms. This process frequently results in black bars, reduced video quality, and critical visual information being cropped out of the frame.
By exporting with the exact specifications for each placement, you maintain control. This ensures your video:
- Maximizes Screen Real Estate: A 4:5 video occupies significantly more vertical space in the Feed than a 16:9 video, which appears small and is easily scrolled past. A 9:16 Reel fills 100% of the mobile screen.
- Avoids Quality Loss: Providing the correct format signals to Instagram's servers that minimal re-compression is needed, preserving the file's original quality and avoiding pixelation.
- Keeps Content Visible: You can design your video knowing that captions, logos, and the main subject will not be hidden behind usernames, buttons, or other interface elements.
Instagram Video Dimensions Cheat Sheet
This section contains the exact specifications required for each video type on Instagram. Using these numbers from the start of your editing process prevents cropping issues, black bars, and resolution loss.
Here is a breakdown of the essential specifications for each major format:
- Reels & Stories: 9:16 aspect ratio (1080 x 1920 pixels). This is the standard for vertical video, filling the entire mobile screen for an immersive viewing experience.
- Feed Video (Portrait): 4:5 aspect ratio (1080 x 1350 pixels). This is the optimal format for the main feed, taking up more vertical real estate than square or landscape posts.
- Feed Video (Square): 1:1 aspect ratio (1080 x 1080 pixels). The original Instagram format, now best used for carousel posts or maintaining a clean, symmetrical grid.
- Feed Video (Landscape): 16:9 aspect ratio (1920 x 1080 pixels). This format appears small and letterboxed in the mobile feed. Use it only when wide framing is essential to the content.
Instagram Video Specifications at a Glance
| Placement | Aspect Ratio | Recommended Dimensions (Pixels) | Primary Use Case |
|---|---|---|---|
| Reels & Stories | 9:16 | 1080 x 1920 | Full-screen, immersive short-form video |
| Feed (Portrait) | 4:5 | 1080 x 1350 | Maximizing screen space in the main feed |
| Feed (Square) | 1:1 | 1080 x 1080 | Classic grid aesthetic, carousels |
| Feed (Landscape) | 16:9 | 1920 x 1080 | Cinematic or traditional wide video (use sparingly) |

From Square to Vertical: How Instagram’s Formats Evolved
Understanding the evolution of Instagram’s video formats explains why the algorithm favors specific dimensions. The platform's shift from a 1:1 square to a 9:16 vertical standard was a direct response to changes in mobile hardware and user behavior.
When Instagram launched in 2010, its identity was the 1:1 square aspect ratio. This constraint defined an era of content creation, forcing photographers and videographers to compose shots within a perfect square, which suited the smaller phone screens of the time.
The first major change occurred in 2015 when Instagram allowed non-square uploads, including landscape (up to 1.91:1) and portrait (4:5). This was a direct acknowledgment that users were naturally shooting content vertically.
The launch of Reels in 2020 solidified vertical video’s dominance. Built to compete with TikTok, Reels adopted the full-screen, immersive 9:16 aspect ratio. The format proved so effective at increasing user watch time that Instagram began prioritizing it across the app.
- 2010: The 1:1 square was the only option.
- 2015: The platform opened to landscape and the taller 4:5 portrait.
- 2020: Reels launched with the full-screen 9:16 format, cementing the vertical-first standard. Today, vertical content drives over 70% of all video views on the platform.
This progression is detailed in this Instagram aspect ratio timeline on Avramify.com. The platform’s algorithm rewards content that maximizes screen real estate. The 9:16 format is engineered to do this, filling every pixel of a mobile screen. Aligning your Instagram video aspect ratio with this trend means you are working with the algorithm, not against it.
Mastering Every Instagram Video Placement
A one-size-fits-all approach to video formatting leads to awkward crops and obscured content. Each placement—Reels, Stories, and Feed—has unique requirements for aspect ratio, dimensions, and UI-driven safe zones.
Instagram Reels: The 9:16 Vertical Standard
Reels require a 9:16 aspect ratio to provide a full-screen, immersive experience. The standard export resolution is 1080 x 1920 pixels.
However, you must design around the user interface (UI) overlays. Placing essential text or visuals where the UI sits will render them unreadable. Safe zones are critical.
- Top Safe Margin: Leave ~14% of the screen height (~270 pixels) clear at the top for the "Reels" header.
- Bottom Safe Margin: Reserve ~25% of the screen height (~475 pixels) at the bottom. This area contains the profile info, caption, audio details, and engagement buttons.
- Side Margins: Maintain a buffer of at least 32 pixels on the left and right sides.
Your usable creative space is significantly smaller than the full 1080x1920 frame. For a detailed breakdown, see our guide on vertical framing and safe zones.
Instagram Stories: Also 9:16, But Different
Instagram Stories also use a 9:16 aspect ratio (1080 x 1920 pixels), but the UI overlays are different from Reels. The most important consideration is the reply bar at the bottom.
- Top Margin: The top area is reserved for your profile icon and username. Leave a buffer of about 250 pixels.
- Bottom Margin: The "Send message" reply field at the bottom occupies roughly 320 pixels. Any content placed here will be completely obscured.
Place interactive elements like polls and stickers in the central viewing area to encourage engagement without clashing with the permanent UI elements.
Instagram Feed Videos: A Tale of Three Ratios
The main feed supports three aspect ratios. Your choice directly impacts how much screen space your video occupies.
1. The Powerhouse: Portrait (4:5)
For in-feed videos, the 4:5 aspect ratio is the most effective. At 1080 x 1350 pixels, it takes up more vertical screen space than any other feed format, which has been shown to increase view duration. Reels are also automatically cropped to a 4:5 preview when shared to the feed.
2. The Classic: Square (1:1)
The 1:1 aspect ratio (1080 x 1080 pixels) is Instagram's original format. While no longer optimal for maximizing screen space, it is the best choice for maintaining a clean, symmetrical grid aesthetic or for creating seamless carousel posts. By 2023, the 1:1 square format represented less than 10% of all video uploads, while vertical videos receive up to 30% more engagement. For more data, consider reading additional insights on Descript.com.
3. The Risky Bet: Landscape (16:9)
Uploading a standard 16:9 landscape video (1920 x 1080 pixels) to the feed is generally not recommended. In a vertical feed, a wide video appears small and is letterboxed with large black bars, which kills its visual impact. Use this format only if wide framing is non-negotiable for the content.
A Technical Workflow for Perfect Video Formatting
Achieving the correct format requires a repeatable, technical workflow. Following a structured process for setting up, reframing, and exporting your video eliminates quality loss and dimensional errors.
The objective is to produce a video file that meets Instagram's exact technical specifications—H.264 codec, AAC audio, and specific bitrates—before uploading. This prevents Instagram's servers from aggressively re-compressing your file and degrading its quality.
Step 1: Set Up Your Sequence Correctly
This step is performed inside your editing software, such as Adobe Premiere Pro, DaVinci Resolve, or Final Cut Pro. You must set your project or sequence settings to match your target Instagram video aspect ratio at the beginning of your edit. Do not edit a 9:16 video in a 16:9 timeline with the intent to crop later.
- For Reels/Stories: Create a custom sequence with dimensions of 1080x1920 (9:16).
- For Portrait Feed Video: Use a sequence of 1080x1350 (4:5).
- For Square Feed Video: Set the sequence to 1080x1080 (1:1).
Step 2: Reframe and Reposition Your Footage
Once your sequence is set, import your source footage. If you shot in landscape (16:9), you must reframe it for the vertical canvas. Use the position and scale controls in your editor to pan and scan the footage, ensuring the main subject remains centered. For example, when editing an interview clip shot in landscape, I use position keyframes to keep the speaker's face in the center third of the 9:16 frame as they move, creating a more dynamic shot than a simple static center-crop.
Step 3: Use Command-Line Automation with FFmpeg
For batch processing, FFmpeg is a command-line tool that allows you to resize, crop, and re-encode videos efficiently.
Here are copy-ready commands for common conversions:
- Convert 16:9 Landscape to 9:16 Vertical (Center Crop): This takes a 1920x1080 input and creates a 1080x1920 output by cropping from the center.
ffmpeg -i input.mp4 -vf "crop=in_h*9/16:in_h,scale=1080:1920" output.mp4 - Convert 16:9 Landscape to 4:5 Portrait (with Padding): This resizes a 16:9 video to fit a 1080x1350 frame, adding black bars (padding) to the top and bottom.
ffmpeg -i input.mp4 -vf "scale=1080:608,pad=1080:1350:(ow-iw)/2:(oh-ih)/2" output.mp4
For those who prefer a graphical interface, our free video aspect ratio converter handles these conversions in a browser.
Step 4: Dial In Optimal Export Settings
Your export settings are the final quality control check. Incorrect settings can result in a file that is too large or looks pixelated.
Use these settings when exporting from any professional video editor:
- Format: MP4
- Codec: H.264
- Frame Rate (FPS): Match source (e.g., 24, 30, 60). Instagram may convert rates above 30 FPS down.
- Bitrate: For 1080p video, a target bitrate of 3.5 Mbps (3,500 kbps) provides a balance of quality and file size.
- Audio Codec: AAC
- Audio Sample Rate: 48 kHz
- Audio Bitrate: 128 kbps
Common Mistakes & Fixes
Even experienced creators encounter formatting issues that reduce video quality. Most problems stem from a mismatch between the exported file and Instagram's specifications for that placement.
- Issue → Black Bars Appear on Video
Fix: The video's aspect ratio does not match the placement's native ratio. Set your editing sequence to the correct dimensions (e.g., 1080x1920 for Reels) before editing. If adapting existing footage, crop to fill the frame or use a stylized blurred background instead of black bars. - Issue → Key Visuals Are Cropped or Covered by UI
Fix: This is a safe zone violation. For a 9:16 Reel, keep all critical elements within a central area, leaving approximately 14% of the frame empty at the top and 25% at the bottom. Use your editor's safe zone overlay guides during the edit. - Issue → Video Looks Blurry or Pixelated After Upload
Fix: Instagram's servers aggressively re-compressed your file. Export with optimized settings: H.264 codec, MP4 container, AAC audio, and a video bitrate of 3.5 Mbps for 1080p footage. This minimizes the need for transcoding. - Issue → Reel Preview is Awkwardly Cropped on Profile Grid
Fix: Instagram automatically generates a 1:1 square thumbnail for the grid. When uploading, tap "Edit cover" and switch to the "Profile grid" tab. Manually drag the frame to select the most visually compelling portion of your cover image for the 1:1 preview.
Frequently Asked Questions
Is square video still relevant on Instagram?
Yes, but in specific contexts. The 1:1 aspect ratio (1080x1080 pixels) is no longer optimal for the main feed, where the taller 4:5 format performs better. Use 1:1 for carousel posts to ensure a smooth swiping experience and for maintaining a symmetrical profile grid aesthetic.
What's the best universal aspect ratio for all platforms?
There is no single universal ratio, but 9:16 is the most versatile for short-form content. A vertical 1080x1920 video is the native format for Instagram Reels, Stories, TikTok, and YouTube Shorts. To create a truly cross-platform video, you must keep all critical text and visuals within a central "universal safe zone" that avoids the UI overlays of all platforms.
How should I handle landscape footage for Instagram?
Do not upload raw 16:9 footage. Instead, choose one of these three methods:
- Pillarbox with a Styled Background: Place the 16:9 clip onto a 9:16 canvas and fill the empty side space with a blurred version of the video or a solid brand color.
- Pan and Scan (Reframing): Edit the 16:9 footage within a 9:16 sequence, using position keyframes to follow the main subject. This creates a dynamic, native-feeling vertical video.
- Split Screen: Divide the 9:16 frame. For example, a travel vlog might show a 16:9 landscape shot in the top half and an animated map in the bottom half.
Why does my video quality drop after uploading?
Quality drops because Instagram's servers re-compressed your file due to non-optimal export settings. To prevent this, export your video as an MP4 file using the H.264 codec. For 1080p 30 FPS video, set the video bitrate to 3.5 Mbps (3,500 kbps) and audio to AAC at 128 kbps.
Reels vs. Stories: What’s the difference in 9:16?
While both use a 9:16 aspect ratio (1080x1920 pixels), their UI and safe zones differ. Reels have a crowded bottom UI, requiring a ~25% bottom margin (475 pixels). Stories have a reply bar at the bottom, requiring a 17% margin (320 pixels), and a profile header at the top requiring a ~13% margin (250 pixels).
