LinkedIn Video Specs and Dimensions Guide

Getting LinkedIn video specs right is the difference between a clip that looks sharp in the feed and one that arrives blurry, cropped, or rejected on upload. This guide collects the LinkedIn video specs that matter most for B2B teams: supported aspect ratios, maximum length and file size, recommended resolution, captions and SRT files, and thumbnails. Treat every number here as practical general guidance. Platforms update their requirements often, so confirm the current details in LinkedIn's own help center before a major launch.

The goal is simple. You should be able to plan, shoot, and edit a video knowing it will display correctly the first time, without guesswork or last-minute re-exports.

Why LinkedIn video specs matter for B2B

Video is now a default format across business platforms, not an experiment. Wyzowl's research found that 91% of businesses use video as a marketing tool, and that 82% of people say a video convinced them to buy a product or service. Those numbers hold up in B2B, where buyers research vendors carefully and want to see the people behind a company before they commit to a call.

LinkedIn rewards native video that plays directly in the feed. When a clip is sized correctly, it autoplays cleanly, fills the right amount of screen space, and keeps a viewer's attention long enough to land your message. When the specs are wrong, the platform compresses your file harder, crops your framing in odd ways, or pushes your text outside the safe area. The fix is to build for the format from the start rather than patching it after the fact.

If you are still shaping your overall approach, our guide to LinkedIn video strategy for B2B brands covers the content side. This article stays focused on the technical specs.

Supported aspect ratios

LinkedIn feed video supports several aspect ratios, and the right choice depends on where the video will appear and how people will watch it.

Square, 1:1. Square video is a strong default for the LinkedIn feed. It takes up more vertical space than a widescreen clip on mobile, which is where most people scroll, and it works well for talking-head clips, quote cards, and simple motion graphics. A common export size is 1080 by 1080 pixels.

Vertical, 4:5. The 4:5 ratio is slightly taller than square and claims even more feed real estate on phones without going fully vertical. It is a good middle ground for B2B clips that want maximum mobile presence while still reading clearly on desktop. A typical size is 1080 by 1350 pixels.

Widescreen, 16:9. The classic horizontal ratio suits webinar recordings, product demos, interviews, and anything originally shot for a horizontal frame. It uses less vertical space in the mobile feed, so it can feel smaller, but it remains the natural format for longer, more produced pieces. A standard size is 1920 by 1080 pixels.

Vertical, 9:16. Full vertical video matches the short-form style people know from other platforms. It is well suited to quick tips, executive sound bites, and reels-style edits. A common size is 1080 by 1920 pixels. If short vertical clips are central to your plan, our short-form video editing service is built for exactly this kind of output.

As a working rule for B2B feed posts, 1:1 and 4:5 tend to perform well because they balance mobile presence with desktop readability. Reserve 16:9 for content that genuinely needs the wide frame.

Maximum length and file size

LinkedIn allows a wide range of video lengths, from a few seconds up to roughly ten minutes for standard feed uploads. The technical maximum is far longer than what you should actually publish. For B2B feed video, the practical sweet spot is usually 30 seconds to 2 minutes. Short clips respect the viewer's time, and they tend to hold attention better than long ones in a scrolling feed.

File size limits are generous, commonly cited in the range of several gigabytes per upload, which is more than enough for a well-compressed clip. Rather than chasing the maximum, aim for the smallest file that still looks clean. A tightly encoded H.264 MP4 will upload faster, transcode more reliably, and avoid the heavy compression LinkedIn applies to bloated files.

These limits shift over time, so check LinkedIn's current help documentation before you plan anything unusually long or large. When in doubt, shorter and lighter is the safer choice.

Recommended resolution and format

For resolution, 1080p is the right target for most LinkedIn video. It looks crisp on both mobile and desktop without creating an oversized file. You can upload 4K source footage, but the platform will compress it for delivery, so exporting a clean 1080p file usually gives you more control over the final look.

For format and codec, use these settings as a reliable baseline:

• Container: MP4
• Video codec: H.264
• Audio codec: AAC
• Frame rate: 24, 25, or 30 frames per second, matched to your source
• Bitrate: high enough to avoid visible blocking, typically 8 to 12 Mbps for 1080p

A clean export at these settings reduces the chance that LinkedIn's own compression degrades your image. If your footage has fast motion or detailed graphics, lean toward the higher end of the bitrate range.

Captions and SRT files

Most people watch feed video with the sound off, at least at first. Captions are not optional for B2B video, they are how your message survives a muted autoplay. LinkedIn supports uploading an SRT caption file alongside your video, which adds toggleable closed captions that viewers can turn on or off.

You have two main options, and the best approach often uses both:

1. Burned-in captions. These are baked directly into the video frame and always visible. They guarantee your words appear no matter the device or setting, and they let you control font, size, and placement to match your brand.
2. Uploaded SRT file. This adds accessible closed captions that screen readers and accessibility tools can use, and it gives viewers who prefer captions off a clean frame.

For maximum reach and accessibility, burned-in captions cover the silent-autoplay problem while an SRT file supports accessibility standards. Keep caption text inside the safe area so the platform interface does not cover it.

Thumbnails and the first frame

LinkedIn lets you set a custom thumbnail, also called a cover image, for your video. This is the still frame people see before the video plays or when autoplay is disabled. A strong thumbnail can lift click-through and watch rates, so it is worth a deliberate choice rather than whatever frame the platform grabs by default.

Match the thumbnail dimensions to your video's aspect ratio so it displays without cropping. Use a clear, high-contrast image, and if you add text, keep it short and large enough to read at a small size. A face looking toward the camera, a bold statistic, or a clean title card all tend to work well for B2B.

Best practices for B2B feed video

Specs get your video onto the platform. These practices help it actually perform.

Hook in the first three seconds. Autoplay means you have a moment to earn attention before someone scrolls past. Open with the payoff, a question, or a striking visual rather than a slow logo animation.

Design for sound off. Assume no audio. Lead with on-screen text, use captions throughout, and make sure the visual story stands on its own.

Keep it tight. A focused 60-second clip usually outperforms a rambling three-minute one. Cut anything that does not move the point forward. Different formats serve different goals, which we break down in our guide to B2B video content types that convert.

Brand consistently but lightly. A small logo, consistent caption styling, and a recognizable color treatment build familiarity. Heavy intros and outros eat the seconds that matter most.

Put leaders on camera. Founder and executive clips consistently draw engagement on LinkedIn because people connect with people. Our piece on executive thought leadership video on LinkedIn covers how to do this without a studio.

Post natively. Upload video directly to LinkedIn rather than linking out to another platform. Native video gets more reach in the feed and avoids sending viewers away.

The wider video marketing picture supports this discipline. HubSpot's video marketing statistics show how central short, captioned, mobile-first video has become to how buyers research and decide.

A quick reference checklist

Before you upload, run through this list:

• Aspect ratio chosen for the feed: 1:1 or 4:5 for most posts, 9:16 for short-form, 16:9 for wide produced pieces
• Resolution at 1080p, exported as H.264 MP4 with AAC audio
• Length trimmed to the 30-second to 2-minute sweet spot for feed video
• Captions burned in, plus an SRT file uploaded for accessibility
• Custom thumbnail set to match the aspect ratio
• A hook in the first three seconds and a clear point throughout

This checklist will cover the vast majority of B2B LinkedIn video uploads. For anything unusual, confirm the current numbers in LinkedIn's help center.

Bottom line

LinkedIn video specs are not complicated once you have them in one place. Choose 1:1 or 4:5 for most feed posts, export 1080p H.264 MP4, keep clips between 30 seconds and 2 minutes, add captions and an SRT file, and set a custom thumbnail. Build for sound-off mobile viewing, hook fast, and post natively. Because platforms update their requirements, treat these numbers as solid general guidance and confirm the current details in LinkedIn's help center before any major launch.

If you would rather not manage exports, codecs, and caption files yourself, that is exactly what Pixel8 Production handles. For a flat $2,000 to $3,000 per month, a dedicated editor delivers spec-correct B2B video in 48 hours, so your team can focus on the message instead of the file settings.
