LinkedIn Image Best Practices: Posts, Pages, Covers

Images on LinkedIn do a different job than anywhere else: they sit beside your name, your title, and your employer, and they get judged accordingly. Real linkedin image best practices are less about beauty and more about legibility, correct framing, and choosing the right format for the content, whether that's an image, a document, or an article. This guide covers the sizes the platform renders, when a PDF carousel beats a graphic, and the crop that ruins most company banners.

Linkedin image best practices, starting with the frame

Professional context, phone width.

The feed default is 1200x627, effectively the same 1.91:1 frame the rest of the professional web uses. Native images near that ratio render predictably on desktop and mobile; extreme shapes get scaled or truncated, and shared links are pushed toward the wide frame regardless of what you attach.

Legibility rules follow from context. LinkedIn gets read on commutes and between meetings, at phone width, with partial attention. Charts need bigger labels than feels natural, and text overlays need heavier contrast than a portfolio piece would tolerate.

There's a rhythm difference too: LinkedIn posts live longer than posts on faster feeds, resurfacing for days as people react and comment. An image with a small flaw gets re-shown, with your name attached, every time the post finds a new audience, which justifies the extra five minutes of care.

Document posts vs images: when the PDF wins

Depth versus the single glance.

The document posts vs images decision comes down to depth. A single 1200x627 graphic delivers one idea in one glance. A document post, LinkedIn's swipeable PDF format, holds ten pages of ideas and earns dwell time as readers swipe, which the feed's ranking notices.

Documents still begin life as images: each page gets designed at fixed dimensions, square or 1200x627, before assembly into a PDF. Resize the page art first, keep one idea per page, and front load the payoff; swipe through rates fall fast after page three.

PDF pages also stay crisp because documents bypass the photo compression pipeline, which makes them the better home for fine line charts and dense tables that a feed image would smear.

Company page image sizes, from logo to hero

Four assets, four geometries.

Company page image sizes are where LinkedIn gets strange. The logo is a 300x300 square. The page banner renders as an 1128x191 strip, a shape almost no photograph naturally fits. Personal profile covers get a roomier 1584x396, and article heroes run a full 1920x1080.

Nothing about those four rectangles is related. That's the argument for generating them from presets rather than eyeballing crops in a design tool at midnight before a launch.

The personal cover carries its own trap: your profile photo overlaps its lower left region on desktop and shifts position on mobile, so treat the bottom strip of the 1584x396 canvas as already occupied.

One graphic through the company banner, worked out

What 5.9:1 really costs.

Input: a 2560x1440 brand graphic headed for the 1128x191 company banner, via the LinkedIn Image Resizer in Cover mode. The target ratio is about 5.9:1, so the full 2560 width stays and a 433 pixel tall band gets cut from the vertical center, then scaled down. Output: 1128x191, containing roughly 30 percent of the original's height.

That number is the lesson. A centered wordmark survives the band; a composed scene doesn't. Company banner art should be designed as a strip from the start, or chosen for a middle section that stands alone.

Run the same math on the roomier personal cover and about 68 percent of the source height survives, which explains why personal covers tolerate photography while company banners punish it.

LinkedIn image mistakes that undercut credibility

Small errors, professional stage.

On a network where your name sits next to every upload, these five sting more than they would elsewhere.

Reusing the personal profile cover as a company banner and cropping the message into fragments
Posting dense multi part slides as one image instead of a swipeable document post
Uploading an intricate logo at 300x300 that turns to noise beside posts and in search results
Letting a shared link generate its own preview when a purpose built 1200x627 was one export away
Sizing text for desktop reading when most of the audience scrolls at phone width

Tips and the tools worth pairing with LinkedIn

Batch the identity.

Refresh the whole identity in one session: post frame, both covers, logo, and article hero from a single source file, so nothing drifts off brand between updates. And keep white space discipline in banner art; LinkedIn's interface is dense, and breathing room reads as confidence.

For the link preview half of the same job, the OG Image Maker produces the 1200x630 share frame. The Image Compressor trims heavyweight hero exports before upload, and the Twitter/X Image Resizer refits the same campaign art for the other feed your marketing calendar cares about.
