LinkedIn Post Image Size: Complete Guide

Mastering LinkedIn Post Image Sizes: The Definitive Guide

When you spend hours crafting the perfect LinkedIn post, the last thing you want is for your visual to show up blurry, awkwardly cropped, or missing half its message. On a professional network where first impressions rule, clean and crisp design is non-negotiable.

Knowing the exact image dimensions for LinkedIn ensures your content looks professional, captures attention instantly, and keeps readers from scrolling right past your hard work.

Why LinkedIn Image Sizes Matter

LinkedIn’s feed is a competitive space. If your image doesn’t fit the platform’s native containers, the algorithm or the interface will forcefully crop it. This often chops off text, hides key data points in infographics, or stretches a low-resolution file into a pixelated mess. Using the correct aspect ratio guarantees your visual renders precisely the way you designed it, whether viewed on a desktop monitor or a mobile phone.

The Cheat Sheet: Optimal LinkedIn Post Image Sizes

Depending on the type of post you are sharing, your ideal dimensions will vary. Here are the core specifications to keep in your design toolkit:

| Post Type | Recommended Dimensions (Pixels) | Aspect Ratio | Best Used For |
| :— | :— | :— | :— |
| Square Feed Post | $1080 times 1080$ | $1:1$ | Infographics, standard updates, quote cards |
| Portrait / Vertical Post | $1080 times 1350$ | $4:5$ | Mobile-first content, high-engagement graphics |
| Landscape / Link Preview | $1200 times 627$ | $1.91:1$ | Shared website links, blog promos, landscape photos |
| Carousel / Document | $1080 times 1080$ (or $1080 times 1350$) | $1:1$ or $4:5$ | Multi-slide guides, PDF slide decks |

Deep Dive: Choosing the Right Format

1. Square ($1080 times 1080$ px) — The Versatile Standard

If you aren’t sure which format to pick, square is your safest bet. It provides a balanced look on both desktop and mobile feeds. It is wide and tall enough to command attention without taking over the entire screen, making it ideal for standard brand graphics and standalone photos.

2. Portrait ($1080 times 1350$ px) — The Engagement Driver

Because a massive share of LinkedIn traffic comes from mobile devices, vertical formats are incredibly powerful. A $4:5$ ratio fills up the maximum allowable vertical real estate on a phone screen. If you want your post to stand out and force the reader to pause their scroll, portrait is the top choice.

3. Landscape ($1200 times 627$ px) — The Link Preview Specialist

This wide rectangular format is the gold standard when you are sharing an external URL or article link. LinkedIn automatically pulls this proportion for link cards, so previewing your assets in this size ensures your article thumbnails look sharp and complete.

Quick Technical Rules of Thumb

• File Size Limit: Keep your image files under 5 MB. Exceeding this limit can cause upload errors or trigger aggressive compression.
• File Formats: Stick to PNG for graphics containing text, logos, or sharp lines. Use JPEG (or JPG) for traditional photographs.
• Resolution Check: Always design at higher resolutions (like $1080$ pixels wide minimum). Letting LinkedIn stretch a tiny image will ruin your crisp design.

Final Polish

Before you hit publish, take a quick second to preview how your post looks on a mobile screen. By matching your layouts to the correct dimensions, you remove visual friction and let your content speak for itself!
