Facebook event cover size
Short answer
This site uses 1920 × 1005 pixels (1.91:1) for an event cover. We could not read an official Meta page that states an event cover size, so treat the figure as a working size, not a rule.
Key takeaways
- 1920 × 1005 is 1.91:1, the same shape as the link-preview image most feeds use (computed).
- We found no Meta help page stating an event cover size; the figure on this page is a working size.
- A 16:9 photo keeps 93% of its area in this frame and a 4:3 photo keeps 70% (computed).
- Across our six test pictures the 1920 × 1005 result was 257 KB to 575 KB as a JPG at quality 0.92.

What a 1920 × 1005 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) | 79% | 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 1920 × 1005, 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 | 0.50× | 575 KB | 189 ms | - |
| Portrait | 2122 × 2644 | 0.90× | 346 KB | 70 ms | - |
| Wide document scan | 3827 × 1588 | 0.63× | 471 KB | 167 ms | 0.96 |
| Square PNG graphic | 5380 × 5432 | 0.36× | 415 KB | 439 ms | 0.93 |
| Small portrait (1060 px) | 1060 × 1320 | 1.81× (enlarged) | 257 KB | 78 ms | - |
| Small landscape (640 px) | 640 × 480 | 3.00× (enlarged) | 286 KB | 30 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 1.93 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 | 575 KB | 2.39 |
| Portrait | 346 KB | 1.43 |
| Wide document scan | 471 KB | 1.95 |
| Square PNG graphic | 415 KB | 1.72 |
| Small portrait (1060 px) | 257 KB | 1.07 |
| Small landscape (640 px) | 286 KB | 1.19 |
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 Facebook event cover size
- Start from a file at least 1920 × 1005 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.

93% of its area (computed).
What is the aspect ratio of 1920 × 1005?
1.91:1, 1.93 megapixels.
How big will the file be?
Our six test pictures came out between 257 KB and 575 KB as JPGs at quality 0.92; detailed photographs are the large end.
Is my picture uploaded?
No. The resizer runs in your browser.
