LinkedIn Video Ad Specs and Formats 2026

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

Because video in message ads requires a click to play, the thumbnail matters more than in any other format. Use a frame that includes a face, text overlay, or a clear visual hook. Generic thumbnails get ignored.

How do LinkedIn event ads with video work?

Event ads promote LinkedIn Events and LinkedIn Live broadcasts. You can attach a video preview to the event promotion. These show up in the feed and target users likely to register.

Aspect ratio: 16:9 or 1:1
Resolution: 1080p recommended
File size: 200MB maximum
Duration: 15-60 seconds recommended (this is a teaser, not the event itself)

Event ad videos should show a clip from a previous event or a direct-to-camera invite from the speaker. Registration rates increase when people can see who they will hear from. If you are running regular LinkedIn Live events, check out our guide on building a full LinkedIn video strategy to make the most of every broadcast.

Does video duration actually affect performance on LinkedIn?

Yes, and the data is clear. LinkedIn's own research shows that videos under 30 seconds see a 200% lift in view completion rates. For brand awareness campaigns, 15-second spots consistently outperform 60-second versions on cost-per-view.

That said, duration depends on objective. Top-of-funnel awareness ads should stay under 30 seconds. Mid-funnel consideration content (product demos, case study snippets) can run 30-90 seconds. Bottom-funnel retargeting videos should be 15-30 seconds with a single clear CTA.

The real performance killer is slow starts. LinkedIn auto-plays video in the feed with sound off, so the first 3 seconds determine whether someone stops scrolling. Lead with motion, text overlays, or a face - not a logo animation. For more on building a complete approach, see our LinkedIn video production guide.

What are the best practices for LinkedIn video creative?

Specs are table stakes. Here is what actually moves performance metrics:

Always add captions. 80% of LinkedIn video is watched without sound. Burned-in captions (not just the auto-generated ones) improve watch time by 12% on average. Use high-contrast text that is readable on mobile.

Front-load the value. State your point in the first 5 seconds. LinkedIn users scroll fast. If your video opens with "Hi, my name is..." you have already lost half your audience.

Match the format to the funnel stage. Square and vertical for awareness (mobile-first). Landscape for longer consideration content that people watch on desktop. Carousel for product comparisons and sequential storytelling.

Test thumbnail images. LinkedIn lets you upload a custom thumbnail. Use it. The default auto-selected frame is almost never the best option. A/B test thumbnails the same way you would test ad headlines.

How do you produce LinkedIn videos at scale without breaking the budget?

Most B2B teams run into the same problem: they know video performs better on LinkedIn, but producing enough content to maintain a consistent presence is expensive and slow with traditional production.

That is the gap Shootsta's LinkedIn video production fills. With a subscription model, your team can produce multiple LinkedIn video formats each month - from thought leadership clips to product demos to event recaps - without managing freelancers or agencies per project.

Get your specs right first, then focus on creative quality and consistency.
