LinkedIn Image Size Guide 2026

Every linkedin image size guide runs into the same confusion: people use one image size for everything and wonder why link previews look cropped oddly while feed photos look fine, or the other way around. LinkedIn actually wants two different shapes depending on what you're posting. A single square image, 1200x1200 pixels, covers standalone feed photos. A wider image, 1200x627 pixels, is what LinkedIn pulls for the thumbnail when you share a link.

LinkedIn image size guide: post image size by use case

Use case	Dimensions	Aspect ratio
Feed image (single photo)	1200 x 1200	1:1
Feed image (portrait)	1080 x 1350	4:5
Link preview thumbnail	1200 x 627	1.91:1
Max file size	No firm photo cap published; keep files under ~5MB	JPG or PNG

Why linkedin photo dimensions 2026 split into two shapes

A square or portrait image posted directly gets you more vertical real estate in a feed that's mostly scrolled on mobile, which is why 1200x1200 or the taller 1080x1350 outperform a wide landscape shot for standalone photo posts. A link preview works differently: LinkedIn generates that thumbnail from your page's Open Graph metadata, not from an image you upload directly, and it's cropped to a wide 1.91:1 frame regardless of what shape the source image is. Upload a square image as your link's preview source and LinkedIn will crop the sides off; set a properly sized 1200x627 Open Graph image on the page you're linking to, and the thumbnail displays clean.

Getting link previews right

If you regularly share blog posts or landing pages on LinkedIn, the fix isn't something you do at posting time, it's something you set once on the page itself. Add a 1200x627 Open Graph image tag to the pages you expect to share, and every link preview from LinkedIn (and most other platforms) will pull that image correctly from then on.

Format and file size notes

• Use JPG for photographs, it compresses well without visible artifacts at these sizes.
• Use PNG for graphics, screenshots, or anything with text or sharp edges, since JPG compression tends to blur fine detail.
• Keep files under 10MB. LinkedIn will accept larger files, but they take longer to process and occasionally get downscaled more aggressively than a properly sized original.

Checking your work before you post

Getting the dimensions right on paper doesn't guarantee the crop looks right in the actual feed, LinkedIn's mobile and desktop views crop slightly differently at the edges. A quick social post preview before you publish catches an awkward crop while you can still fix it, and the social media image resizer handles converting a source photo to the right dimensions for feed posts versus link thumbnails in one pass.

Once your images are sized correctly, Posted Once schedules them to LinkedIn and nine other platforms from a single composer, so you're not re-uploading and re-cropping the same image five times. Start scheduling free →
