LinkedIn post image size
Short answer
LinkedIn Help gives 1200 × 627 pixels (1.91:1) for a link preview image. Images 200 px wide or narrower show as a small thumbnail on the left, and image-only posts keep other ratios in full on mobile with white padding.
Key takeaways
- 1200 × 627 is 1.91:1, the same shape as Instagram's widest uncropped photo (computed).
- Narrow images (200 px or less) become a small left thumbnail instead of the large card.
- A 16:9 photo keeps 93% of its area in this frame; a square keeps 52% (computed).
- Across our six test pictures the 1200 × 627 result was 133 KB to 249 KB as a JPG at quality 0.92.

What a 1200 × 627 frame does to common photo shapes
The frame is 1.91:1. A photo of another shape is scaled until it covers the frame and the excess is cut from the center, which is what the resizer on this page does. This is computed from the shapes.
| Photo shape | Share of the photo kept | What is cut |
|---|---|---|
| 16:9 (1920 × 1080) | 93% | The top and bottom |
| 3:2 (3000 × 2000) | 78% | The top and bottom |
| 4:3 (4000 × 3000) | 70% | The top and bottom |
| 1:1 (2000 × 2000) | 52% | The top and bottom |
| 4:5 (1080 × 1350) | 42% | The top and bottom |
| 9:16 (1080 × 1920) | 29% | The top and bottom |

Measured: six pictures through the resizer
The resizer on this page was run in headless Chromium on six test pictures (public domain NASA scans, a PNG graphic and two small pictures made from them): each is scaled to cover 1200 × 627, drawn on a white background and saved as a JPG at quality 0.92. SSIM compares each result with a Lanczos crop of the same picture made by ffmpeg (1.0 would be identical); it is blank when the frame has an odd side, which ffmpeg's check cannot compare. Other browsers use their own encoders, so sizes can differ.
| Picture | Pixels | Scale | Result | Time | SSIM |
|---|---|---|---|---|---|
| Photo, nearly square | 3840 × 3877 | 0.31× | 249 KB | 13 ms | - |
| Portrait | 2122 × 2644 | 0.57× | 162 KB | 11 ms | - |
| Wide document scan | 3827 × 1588 | 0.39× | 194 KB | 10 ms | 0.90 |
| Square PNG graphic | 5380 × 5432 | 0.22× | 177 KB | 10 ms | 0.89 |
| Small portrait (1060 px) | 1060 × 1320 | 1.13× (enlarged) | 133 KB | 10 ms | - |
| Small landscape (640 px) | 640 × 480 | 1.88× (enlarged) | 152 KB | 10 ms | - |
A scale above 1 enlarges the picture to fill the frame; enlarging adds no detail, so start from a file at least as large as the frame.
Detail decides the file size (measured)
The same frame holds 0.75 megapixels whatever the picture, but the JPG size follows the detail in it. Bits per pixel is the file size in bits divided by the number of pixels in the frame.
| Picture | Result | Bits per pixel |
|---|---|---|
| Photo, nearly square | 249 KB | 2.65 |
| Portrait | 162 KB | 1.72 |
| Wide document scan | 194 KB | 2.06 |
| Square PNG graphic | 177 KB | 1.88 |
| Small portrait (1060 px) | 133 KB | 1.41 |
| Small landscape (640 px) | 152 KB | 1.62 |
Smooth areas and flat color compress to a fraction of what fine detail needs; a photograph full of texture is the expensive case. If a size limit matters, check your own picture, not an average.
Using the LinkedIn post image size
- Start from a file at least 1200 × 627 pixels so nothing is enlarged.
- Keep faces, logos and text away from the edges; every crop above cuts the edges.
- Check the platform's own page before you rely on a figure; sizes change.
- The resizer above does the crop and the JPG in your browser; nothing is uploaded.
