Best Video Format for Instagram: Sizes, Specs & Pro Tips for 2026

Ever tried posting a video to Instagram only to have it look pixelated, cropped weirdly, or just off? You’re not alone. Getting your videos to look professional on Instagram isn’t just about good content, it’s about understanding what the platform actually wants from your files.

Instagram has specific requirements for each type of video content, and knowing these details can make the difference between a video that stops scrollers in their tracks and one that gets ignored. Let’s break down exactly what you need to know to make your Instagram videos shine in 2025.

Instagram Video Format Parameters

Before discussing specific recommendations for each Instagram video type, let’s understand the basic elements that affect how your videos appear and perform.

Video Format

Video format is simply the container file type that holds your video data. Here are the two formats that Instagram supports:

• MP4 (most widely supported)
• MOV (good alternative, especially if you’re editing on Apple devices)

It’s possible that Instagram can accept other formats, but you should stick with MP4 or MOV video formats to make sure that your videos get uploaded smoothly and with the best quality.

Video Codec

Think of a codec as the method used to compress your video file. Without compression, video files would be enormous and impossible to upload quickly.

Instagram works best with:

• H.264 for video
• AAC for audio

Using these codecs gives you the best balance between file size and quality preservation. Other codecs can work, but Instagram might process them more, which could lower your video quality.

Aspect Ratio

Aspect ratio means the shape of your video—how wide it is compared to how tall it is. If it’s not right for Instagram, your video might get cropped or have black bars added.

Common Instagram aspect ratios include:

• 1:1 (square)
• 4:5 (vertical for feed)
• 16:9 (horizontal/landscape)
• 9:16 (vertical for Stories and Reels)

You should choose the right aspect ratio for each type of content to make sure that your video displays correctly without unwanted cropping.

Resolution

Resolution determines how sharp and clear your video appears. It’s measured in pixels (width × height).

For best results on Instagram:

• Feed videos: At least 1080 pixels wide
• Stories and Reels: 1080 × 1920 pixels

Higher resolution means better quality, but remember that Instagram will compress your video anyway, so ultra-high resolutions (like 4K) don’t necessarily translate to better-looking videos on the platform.

Frame Rate

Frame rate measures how many individual images (frames) are displayed per second in your video. Most Instagram videos use:

• 30 fps (frames per second) for standard content
• 60 fps for smoother motion in action videos

While higher frame rates create smoother-looking videos, they also increase file size. For most content, 30 fps offers a good balance between smoothness and file size.

Bitrate

Bitrate represents how much data your video uses per second of playback. Higher bitrates mean better quality but larger files.

For Instagram videos:

• 3-5 Mbps for standard content
• 5-8 Mbps for higher quality content with lots of motion

Instagram will compress your video regardless of the original bitrate, but starting with a decent bitrate helps maintain quality through the compression process.

Video Length

Each Instagram video format has different length limitations:

• Feed videos: Up to 60 minutes
• Stories: 15 seconds per segment
• Reels: Up to 90 seconds

Just because you can make a video long doesn’t mean you should. Shorter videos typically perform better, with 15-30 seconds being the sweet spot for engagement on most formats.

Best Video Format for Instagram Feed

Instagram Feed videos appear directly in users’ main scrolling feed. Here’s what works best:

• Preferred format: MP4 with H.264 codec 
• Ratio: 4:5 vertical (recommended for maximum screen space), 1:1 square, or 16:9 horizontal 
• Frame rate: 30 fps 
• Resolution: 1080 × 1350 pixels (for 4:5 ratio) 
• Length: 3 seconds to 60 minutes (but 15-30 seconds performs best) 
• Maximum file size: 4GB

Pro tip: The 4:5 vertical ratio takes up the most screen space in the feed, making your video more noticeable as users scroll.

Best Video Format for Instagram Stories

Stories appear full-screen and disappear after 24 hours (unless saved to Highlights).

• Format: MP4 with H.264 codec 
• File size: Up to 4GB 
• Length: 15 seconds maximum per segment (longer videos are automatically split)
• Resolution: 1080 × 1920 pixels 
• Aspect ratio: 9:16 (full-screen vertical) 
• Video settings: 30 fps, 3-5 Mbps bitrate

Pro tip: Since Stories are designed for mobile viewing, always shoot in vertical orientation to avoid black bars at the top and bottom.

Best Video Format for Instagram Reels

Reels are Instagram’s answer to TikTok—short, engaging videos with music and effects.

• Format: MP4 with H.264 codec
• File size: Up to 4GB 
• Length: Up to 90 seconds 
• Ratio: 9:16 (vertical) 
• Video settings: 30 fps, 4-8 Mbps bitrate for clearer quality 
• Resolution: 1080 × 1920 pixels

Pro tip: Reels get the most distribution when they’re created natively in the app, but uploading pre-edited videos gives you more control over quality and effects.

Best Video Format for Instagram Ads

Instagram Ads have specific requirements based on their placement and format:

• Vertical Video Resolution: 1080 × 1920 pixels
• • Aspect ratio: 9:16 
  • Max size & length: 4GB, up to 60 seconds (recommended: 15 seconds)
• Landscape Video Resolution: 1920 × 1080 pixels
• • Aspect ratio: 16:9 
  • Max size & length: 4GB, up to 60 seconds (recommended: 15 seconds)
• Square Video Resolution: 1080 × 1080 pixels
• • Aspect ratio: 1:1 
  • Max size & length: 4GB, up to 60 seconds (recommended: 15 seconds)

Pro tip: For ads, the first 3 seconds are crucial. Make them count with movement, text overlays, or something visually striking to stop the scroll.

How to Improve Instagram Video Quality

Shoot in High Resolution

Record in at least 1080p, even if you’re just using your phone. This gives you more flexibility during editing and ensures your final video looks crisp after Instagram’s compression.

Choose the Right Lighting

Good lighting makes a massive difference. Natural light works great, but if that’s not an option, even a basic ring light can dramatically improve your video quality. Avoid backlighting (like sitting with a window behind you), which creates silhouettes.

Stabilize Your Camera

Shaky footage looks amateur. Use a tripod, gimbal, or even prop your phone against something stable. Many phones now have built-in stabilization, but physical stabilization always works better.

Adjust Frame Rate for Smoothness

For most content, 30 fps works perfectly. If you’re capturing fast action or want super-smooth motion, bump it up to 60 fps, but be aware this creates larger files.

Optimize Video Format and Codec

Export your videos as MP4 files with H.264 video codec and AAC audio codec. This combination provides the best quality-to-size ratio for Instagram.

Use Proper Aspect Ratio

Match your aspect ratio to where your video will appear:

• Feed: 4:5 vertical or 1:1 square
• Stories/Reels: 9:16 vertical

Using the wrong ratio means Instagram will crop your video or add black bars.

Ensure Proper Video Bitrate

Higher bitrates mean better quality but larger files. For Instagram:

• Standard quality: 3-5 Mbps
• Higher quality: 5-8 Mbps

Edit with Professional Tools

Basic editing can transform your video quality. ZapCap offers professional-grade editing tools without the learning curve, letting you improve colors, add transitions, and polish your content.

Add Captions and Sound with ZapCap

Export with Instagram’s Video Settings

When exporting your final video, use these settings for optimal results:

• Format: MP4
• Video codec: H.264
• Audio codec: AAC
• Resolution: At least 1080p on the longest side
• Bitrate: 3-8 Mbps depending on content type
