Enter width and height to check.
Commonly used sizes
| Format | Pixels |
|---|---|
| Landscape (1.91:1) | 1200 × 627 |
| Square (1:1) | 1200 × 1200 |
| Portrait (4:5) | 1080 × 1350 |
The supported range (3:1 to 4:5) is the figure sources agree on. The pixel values in the table are widely used recommendations, not a published LinkedIn rule: any size inside the range displays uncropped.
How to use it
- Find your image dimensionsOn Windows, right-click → Properties → Details. On Mac, Cmd + I.
- Enter width and heightIn pixels. Order matters: width first.
- Read the verdictIt tells you whether it fits uncropped and which standard format it's closest to.
Pixels aren't what matters
Almost every guide starts by handing you a list of exact sizes. The problem is that LinkedIn doesn't require a specific size: it accepts a range of aspect ratios, and anything inside that range shows in full.
The range runs from 3:1 (very wide) to 4:5 (portrait). Inside it, your image displays complete. Outside it, it gets cropped and you lose whatever sat near the edges.
So this tool calculates the ratio instead of matching you against a table. The ratio is arithmetic and always right; a pixel table goes stale every time LinkedIn touches the feed.
Where cropping usually bites
The most common case is desktop screenshots. A full-screen capture is usually 16:9, which is 1.78:1 and fits fine. But a long narrow capture of a wide panel or a spreadsheet easily exceeds 3:1.
The other case is vertical phone photos. An iPhone portrait shot is 3:4, which is 0.75 — below the 0.8 allowed. It gets cropped top and bottom.
If your image has text near the edge, that text is the first thing to disappear.
Portrait fills more screen, at a cost
A 4:5 image takes more vertical space in the feed, which is why many people prefer it: it's more visible.
The cost is that it pushes text up. The taller the media, the fewer lines of text remain visible before "…see more".
It's a real trade: bigger image or longer hook. The preview tool shows exactly how much text you keep in each case.
Resolution: when it looks soft
Being inside the ratio range avoids cropping, but doesn't guarantee sharpness.
Below around 1080 pixels wide, the image stretches on large screens and loses definition. On mobile you won't notice; on a desktop monitor you will.
Practical rule: pick the ratio by how you want it to look in the feed, then make sure the width reaches at least 1080.
Frequently asked questions
- What's the best size for a LinkedIn post?
- Depends what you want. Portrait (1080 × 1350) fills more screen; square (1200 × 1200) is the middle ground; landscape (1200 × 627) leaves more text visible before the cut.
- Does LinkedIn crop my images?
- Only if the ratio falls outside 3:1 to 4:5. Inside that range it shows in full.
- Why does my image look blurry?
- Almost always low resolution, not ratio. Below 1080 px wide it shows on large screens.
- Can I upload a vertical phone photo?
- You can, but an iPhone portrait shot is 3:4 and falls outside the allowed range: it gets cropped top and bottom. Crop it to 4:5 yourself first.
- Does the image affect how much text shows?
- Yes. The taller the image, the fewer lines of text remain before "…see more".
- Do I need an account?
- No. The calculation runs in your browser.
