LinkedIn Video Ad Specs and Formats 2026
Every LinkedIn video ad format with exact specs, dimensions, file size limits, and duration caps. Updated for 2026 with performance data on what actually works.
What LinkedIn video ad formats are available in 2026?
LinkedIn offers more video ad formats than most marketers realize. Each format has different specs, different placement rules, and different performance characteristics. Getting the specs wrong means your video gets rejected, cropped badly, or looks amateur in the feed.
Here is every format available right now, with the exact technical requirements you need to hit before uploading.
What are the specs for sponsored content video ads?
Sponsored content video is the default LinkedIn video ad format. It appears directly in the feed and accounts for roughly 80% of all video ad spend on the platform. These are the specs:
- Aspect ratios: 16:9 (landscape), 1:1 (square), 9:16 (vertical), 4:5 (vertical)
- Resolution: Minimum 360p, recommended 1080p or higher
- File size: 75KB minimum, 200MB maximum
- Duration: 3 seconds to 30 minutes
- File formats: MP4 only
- Frame rate: 30fps recommended (up to 60fps supported)
- Audio: AAC or MPEG4, under 64KHz not recommended
Square (1:1) and vertical (4:5) formats take up more screen real estate on mobile, which is where 65% of LinkedIn usage happens. Internal data from LinkedIn shows that vertical and square videos get 15-20% higher completion rates than landscape on mobile devices.
How do carousel video ads differ from single video?
Carousel ads let you combine up to 10 cards, and each card can be a video or an image. This format works well for product walkthroughs, multi-step processes, or comparing features side by side. The specs per card:
- Aspect ratio: 1:1 only (all cards must match)
- Resolution: 1080x1080 recommended
- File size: 200MB maximum per card
- Duration: Up to 30 minutes per card (but keep it under 60 seconds per card for engagement)
- Cards: 2-10 per carousel
Carousels generate 2-3x the click-through rate of single-image ads, according to LinkedIn's own campaign benchmarks. The video version performs even better when each card tells a sequential story rather than presenting standalone clips.
What specs apply to LinkedIn message ads with video?
Sponsored messaging (formerly InMail) now supports video attachments and embedded video. This format reaches people directly in their LinkedIn inbox, which means higher open rates but stricter targeting requirements.
- Aspect ratio: 16:9 recommended
- Resolution: 1080p recommended
- File size: 200MB maximum
- Duration: Keep under 2 minutes - inbox context means people expect brevity
- Auto-play: No - user must click to play
