LinkedIn Video Ad Aspect Ratios
LinkedIn supports 5 aspect ratios:
1:1 Square (Recommended)
Dimensions: 1080 x 1080 pixels Aspect ratio: 1:1
Why recommended:
- Takes up most vertical space on mobile (80% of LinkedIn users)

- Higher engagement rate (15-30% better than horizontal)
- Works well in feed
Best for:
- Feed video ads
- Sponsored content
- Mobile-first campaigns
16:9 Horizontal (Landscape)
Dimensions: 1920 x 1080 pixels Aspect ratio: 16:9
Why use:
- Traditional video format
- Desktop-optimized
- Existing video content often in this format
Trade-offs:
- Letterboxing on mobile (black bars top/bottom)
- Takes less vertical space in feed
- Lower mobile engagement
Best for:
- Repurposing YouTube content
- Professional/corporate videos
- Desktop-heavy audiences
9:16 Vertical (Portrait)
Dimensions: 1080 x 1920 pixels Aspect ratio: 9:16
Why use:
- Instagram Stories/TikTok format
- Full-screen mobile experience
- Maximum vertical space
Trade-offs:
- Letterboxing on desktop (black bars left/right)
- Less common on LinkedIn than 1:1
Best for:
- Mobile-only campaigns
- Story-style content
- User-generated content
2.4:1 Ultra-Wide
Dimensions: 2400 x 1000 pixels (or similar) Aspect ratio: 2.4:1
Why use:
- Cinematic look

- Landscape panoramas
Trade-offs:
- Significant letterboxing on all devices
- Uncommon, may look odd in feed
Best for:
- Specific creative needs only
Custom Aspect Ratios
LinkedIn accepts custom ratios between 1:2.4 and 2.4:1.
Example accepted:
- 4:5 (1080x1350)
- 2:3 (1080x1620)
Not recommended: Stick to standard ratios (1:1, 16:9, 9:16) for best results.
Video File Specifications
Supported File Formats
✅ MP4 (most common, recommended) ✅ MOV (Apple QuickTime) ✅ AVI (Audio Video Interleave) ✅ ASF (Advanced Systems Format) ✅ FLV (Flash Video) ✅ MPEG-1 (Moving Picture Experts Group) ✅ MKV (Matroska Video) ✅ WebM (Web Media) ✅ WMV (Windows Media Video)
Best practice: Export as MP4 with H.264 codec for maximum compatibility.
Video Codec
Recommended: H.264 (AVC) Alternative: H.265 (HEVC) for smaller file sizes
Audio codec: AAC (Advanced Audio Coding)
Export settings:
- Container: MP4
- Video codec: H.264
- Audio codec: AAC
- Frame rate: 30 FPS
- Bitrate: 3-5 Mbps
File Size Limits
Maximum: 200MB per video Recommended: Under 50MB
Why smaller is better:
- Faster upload to LinkedIn
- Faster loading for viewers (lower bounce)
- Better mobile experience (less data usage)
How to reduce file size:
- Lower resolution (1080p → 720p acceptable)
- Compress with HandBrake or similar tool
- Reduce bitrate (5 Mbps → 3 Mbps)
- Shorten video length
Video Length
Minimum: 3 seconds Maximum: 30 minutes Optimal: 6-15 seconds for feed ads
Auto-play threshold:
- Under 30 seconds: Auto-plays in feed (muted)
- Over 30 seconds: Requires click to play
Length by objective:
- Brand awareness: 6-15 seconds (attention span)
- Product demo: 30-60 seconds (explain features)
- Thought leadership: 60-120 seconds (share insights)
- Webinar promo: 15-30 seconds (tease content)
Performance data:
- 0-10 seconds: 85% view-through rate
- 11-30 seconds: 60% view-through rate
- 31-60 seconds: 40% view-through rate
- 60+ seconds: 25% view-through rate
Recommendation: Keep under 15 seconds for maximum reach.
Frame Rate
Recommended: 30 FPS (frames per second) Acceptable: 24 FPS, 60 FPS Avoid: Under 24 FPS (appears choppy)
Cinematic look: 24 FPS Smooth motion: 30 FPS Sports/action: 60 FPS (but large file size)
Most common: 30 FPS balances quality and file size.
Resolution and Quality
Minimum resolution:
- 360p (640x360 for 16:9)
Recommended resolution:
- 1080p (Full HD)
- 1920x1080 for 16:9
- 1080x1080 for 1:1
- 1080x1920 for 9:16
Higher resolutions:
- 2K (2560x1440): Supported but unnecessary (larger files)
- 4K (3840x2160): Supported but overkill (very large files, slow loading)
Best practice: 1080p provides excellent quality at reasonable file size.
Bitrate
Maximum: 5 Mbps (megabits per second) Recommended: 3-5 Mbps
Lower bitrate:
- Smaller file size
- Faster loading
- Acceptable quality for most content
Higher bitrate:
- Better quality
- Necessary for fast motion or detailed graphics
- Larger files
How to check bitrate:
- Use MediaInfo or VLC Player
- Right-click video > Properties > Details
Audio Specifications
Audio Requirements
Audio track: Optional but highly recommended
Why include audio:
- 80% of LinkedIn video views have sound on (desktop)
- 30% of mobile users enable sound
- Increases engagement and message retention
Audio codec: AAC Sample rate: 44.1 kHz or 48 kHz Bitrate: 128 kbps minimum, 192-320 kbps recommended Channels: Stereo (2 channels)
Captions/Subtitles
LinkedIn auto-generates captions for all videos.
Why you should upload custom captions:
- LinkedIn's auto-captions are 70-80% accurate
- Custom SRT files are 95%+ accurate
- Better viewer experience
- Higher engagement (viewers watch longer)
How to add custom captions:
- Create SRT file (SubRip Text format)
- Campaign Manager > Upload video
- Click "Add captions"
- Upload .srt file
SRT file structure:
1
00:00:00,000 --> 00:00:03,000
Welcome to our product demo.

00:00:03,000 --> 00:00:06,000
Here's how it works.
Free tools to create SRT:

- Video must make sense without audio
Best practices:
- Add text overlays (key messages)
- Use captions
- Visual storytelling (show don't tell)
- Brand logo visible
- Clear CTA on-screen
Video Thumbnail Specifications
Auto-Generated vs Custom Thumbnail
Auto-generated:
- LinkedIn picks frame from video (usually first frame)
- No control over which frame selected
Custom thumbnail:
- Upload custom image (1920x1080px JPG or PNG)
- Full control over what viewers see before clicking play
- Recommended for professional appearance
Custom Thumbnail Specs
Dimensions: 1920 x 1080 pixels (16:9) File format: JPG or PNG File size: Under 2MB Aspect ratio: 16:9 (LinkedIn crops if different)
Design best practices:
- Eye-catching visual (bright colors, faces, contrast)
- Text overlay with key message (48pt+ font size)
- Brand logo in corner
- Play button overlay (optional - LinkedIn adds auto play icon)
- Avoid clickbait (thumbnail should match video content)
Tools to create thumbnails:
- Canva (templates available)
- Photoshop
- Figma
Video Ad Text Specifications
Introductory Text
Character limit: 150 characters Appears: Above video in feed Best practices:
- Use 100-130 characters (full 150 may be cut off on mobile)
- Hook viewers in first sentence
- Include benefit or question
- No emojis unless brand-appropriate
Examples:
✅ Good: "Our customers save 10 hours/week with this feature. See how in 60 seconds." (77 characters, clear benefit, creates curiosity)
❌ Bad: "Check out our latest video showcasing our product features and capabilities." (78 characters, vague, no hook)
On-Screen Text
Best practices for text in video:
- Minimum 48pt font (legible on mobile)
- High contrast (white text on dark background)
- Keep text on screen 3+ seconds (time to read)
- Avoid bottom 20% of frame (can be cut off by UI elements)
- Limit to 5-7 words per screen
Text hierarchy:
- Main message: 72-96pt
- Supporting text: 48-60pt
- Fine print: 36pt minimum
Video Ad Performance Optimization
First 3 Seconds Rule
80% of users decide to watch or scroll within 3 seconds.
Hook viewers immediately:
- Lead with biggest benefit
- Show unexpected visual
- Ask provocative question
- Use pattern interrupt (surprise element)
Bad starts:
- Long logo animation (5+ seconds)
- Slow fade-in
- Generic establishing shot
- Talking head with no context
Good starts:
- Product in action
- Customer results (stat/visual)
- Problem/pain point shown
- Eye-catching visual
Video Length by Placement
Feed ads (in-stream):
- 6-15 seconds optimal
- Auto-play under 30 seconds
- Users scrolling quickly
Video views campaigns:
- 30-90 seconds acceptable
- Users intentionally chose to watch
- Can tell longer story
LinkedIn Live:
- 10-60 minutes
- Event/webinar format
- Engaged audience
Mobile Optimization
Design for mobile first (80% of views):
- Use 1:1 square or 9:16 vertical
- Large text (readable at 400px width)
- Simple visuals (not cluttered)
- Bright, high-contrast imagery
- Test on actual mobile device before launching
Audio Strategy
Best practice: Include audio AND design for sound-off
How:
- Add key messages as text overlays
- Upload accurate captions
- Ensure visual story works without sound
- But include audio for desktop users who enable it
Call-to-Action
On-screen CTA (last 3-5 seconds):
- "Learn More"
- "Book a Demo"
- "Download Guide"
- "Visit Website"
End screen:
- CTA text: 72pt+
- Brand logo
- URL (if appropriate)
- Leave on screen 3+ seconds
