The max video length for LinkedIn video ads is 30 minutes for sponsored content in the feed, but that technical ceiling has almost nothing to do with what you should actually upload. If you're planning a campaign, the real question isn't "what's allowed" — it's "what length gets watched, clicked and converted on a platform where people are scrolling between work tasks." This guide covers both: the hard limits by placement, and the practical lengths worth testing.
LinkedIn's actual video length limits, by placement
LinkedIn doesn't have a single video ad format — it has several, and each one has its own technical boundaries. Here's the breakdown that matters before you even open your editing tool.
| Placement | Max length allowed | Typical length that performs |
|---|---|---|
| Single Video Ads (feed) | 30 minutes | 15–60 seconds |
| Carousel-style video within Sponsored Content | Up to 30 minutes per video | 15–30 seconds |
| Conversation Ads (video component) | Short clips only, generally under a few minutes | 6–15 seconds |
| Message Ads (InMail-style) | Does not natively support embedded long video; link out instead | N/A |
| LinkedIn Stories (where available) | Short-form, similar to other platforms' stories | 10–20 seconds |
The 30-minute ceiling for standard feed video ads exists mainly so B2B advertisers can run webinar replays, product demos or recorded panels as paid content. It's a technical allowance, not a recommendation. Almost no advertiser should be uploading a 20-minute video and expecting cold-audience engagement from it.
Why the max length and the right length are different numbers
LinkedIn's audience behaves differently from TikTok or Instagram. People are often on a laptop at work, scanning a feed between tasks, or quickly checking on a phone during a commute. That context changes what a video needs to do in its first few seconds and how much runtime it can justify.
Three rules of thumb to test for feed placements:
- If the goal is brand awareness or top-of-funnel reach, aim for 15–30 seconds. Treat the first 3 seconds like a headline: state the problem or benefit immediately.
- If the goal is lead generation or demo requests, 30–60 seconds gives room to show the product doing something concrete before the call to action.
- If you're repurposing a webinar, panel, or long-form explainer, cut a highlights version under a minute for the feed and let a longer cut live as a native video post or landing-page asset, not a paid ad.
What actually works for LinkedIn video ads: a length-by-goal breakdown
Cold awareness campaigns
Short wins here. A 15–20 second video that opens on a clear statement — a pain point, a stat framed honestly as something to validate with your own testing, or a bold claim about the outcome — tends to hold attention better than a slow build. LinkedIn viewers scrolling past sponsored content are deciding fast whether this is relevant to their job, their team, or their budget.
Retargeting and mid-funnel nurture
Once someone has already visited your site or engaged with a previous ad, you can afford more runtime. A 45–60 second video that walks through a specific feature, shows a before/after, or answers a common objection performs well because the audience already has context and intent.
Thought leadership and brand story
Longer-form video (60–90 seconds, occasionally more) works when it's genuinely narrative — a founder explaining a decision, a customer describing a workflow change. These need stronger pacing and visual variety to avoid drop-off, since there's no algorithmic reward for holding attention the way there is on short-video platforms.
Event promotion and webinar replays
If you're running the technical max — a full webinar or panel recording — don't run it as a cold-audience ad. Use it to retarget people who already registered or attended, where the long runtime is expected and welcome.
Length isn't the only spec that matters
Duration gets the most attention because it's the easiest number to search, but file size, aspect ratio, and resolution all affect whether your ad renders cleanly and loads fast on LinkedIn's feed. A video that's technically under 30 minutes but oversized in file weight can still fail to upload or buffer badly on mobile data. If you want the full technical rundown — resolution, bitrate, supported formats — it's worth checking a dedicated breakdown of video specs for LinkedIn video ads and a separate look at max file size for LinkedIn video ads before you export your final file.
If you're trying to settle on a single best-practice number rather than just the ceiling, the companion piece on recommended video length for LinkedIn video ads goes deeper into testing ranges by objective.
A practical checklist before you upload
- Confirm your placement (feed, Conversation Ad, Stories) and check that placement's own length rule — don't assume the 30-minute feed max applies everywhere.
- Write a cold open: the first 3 seconds should work even with sound off, since many viewers will be scrolling on mute.
- Match length to funnel stage: short for cold reach, longer only when the audience already has context.
- Keep captions on screen — LinkedIn's professional context means plenty of viewing happens in quiet offices or on mute during commutes.
- Export in a mobile-friendly frame. Vertical 9:16 or square 1:1 generally takes up more feed space than horizontal 16:9 on mobile.
- Re-check file size against LinkedIn's upload limits after final export, since re-encoding can change weight even if runtime is unchanged.
How this compares across other ad platforms
If you're running the same campaign idea across multiple networks, it helps to see how LinkedIn's rules sit next to the others. The short version: LinkedIn is unusually permissive on the top end, but the audience still rewards brevity in most placements, much like Instagram and TikTok feeds.
| Platform | Max allowed | Recommended for feed/cold audiences |
|---|---|---|
| LinkedIn feed | 30 minutes | 15–60 seconds |
| Instagram Reels ads | See the Instagram Reels max length guide | 15–30 seconds |
| Instagram Stories ads | See the Instagram Stories max length guide | 10–15 seconds |
| TikTok In-Feed ads | See the TikTok In-Feed max length guide | 9–21 seconds |
| Facebook Stories ads | See the Facebook Stories max length guide | 10–15 seconds |
| YouTube Bumper ads | See the YouTube Bumper max length guide | 6 seconds (fixed format) |
For the platform-specific details behind each row above, see max video length for Instagram Reels ads, max video length for Instagram Stories ads, max video length for TikTok In-Feed ads, max video length for Facebook Stories ads and max video length for YouTube Bumper ads.
The pattern across every platform, LinkedIn included, is the same: the technical maximum exists to accommodate edge cases, while the videos that actually convert tend to cluster in a much tighter, shorter range. Treat the max as a boundary, not a target.
Making a short, feed-ready version without starting from scratch
A common bottleneck for B2B and e-commerce teams alike isn't knowing the ideal length — it's producing a clean, short video fast enough to actually test multiple lengths and hooks before a campaign deadline. This is where a tool like FrameNotion can shortcut the production step: paste a product or landing page link, and FrameNotion AI writes and renders a 30-second vertical video ad from scratch, complete with a hook, problem, benefit, proof and call to action, along with an AI voiceover, music, and word-by-word captions. It's built as a 9:16 MP4 but also comes out as 4:5, 1:1 and 16:9, so you can drop the same ad into LinkedIn's feed, Stories, or square carousel without reshooting anything.
Since the ad is designed to work with sound on or off, it fits the way LinkedIn audiences actually watch — scrolling quietly at a desk or glancing at a phone between meetings. You can see finished examples on the examples page, or read how the process works on the features page.
Frequently asked questions
Can a LinkedIn video ad really be 30 minutes long?+
Yes, for standard Single Video Ads in the feed, LinkedIn's technical maximum is 30 minutes. In practice this is meant for webinar replays or long-form content, not cold-audience campaigns, where much shorter videos perform far better.
What's the minimum video length LinkedIn allows for ads?+
LinkedIn generally requires video ads to run at least a few seconds, with most placements accepting anything from around 3 seconds up to their stated maximum. Check the current placement requirements at upload time since minimums can vary slightly by format.
Does a shorter LinkedIn video ad cost less to run?+
Length itself doesn't set your cost — LinkedIn's bidding and budget system works independently of video duration. Shorter videos can indirectly improve efficiency if they hold attention better and drive stronger engagement, but that's a performance effect, not a pricing rule.
Should LinkedIn video ads be vertical or horizontal?+
Vertical 9:16 or square 1:1 framing tends to take up more space in the mobile feed, which is worth testing against horizontal 16:9 if a meaningful share of your audience is on phones rather than desktop.
Can I use the same short video ad on LinkedIn and other platforms?+
Often yes, especially if it's exported in multiple aspect ratios. A 15–30 second vertical or square video built for Instagram or TikTok can usually run on LinkedIn as well, as long as it fits the platform's file size and format requirements.
