Facebook cover photo最大size

As of my last update in mid 2023, the maximum size for a Facebook cover photo is 820 pixels wide by 462 pixels tall on desktop and 640 pixels wide by 360 pixels tall on mobile. However, it's important to note that Facebook may crop or adjust the cover photo to fit different devices and screen sizes.

To ensure your cover photo looks its best across all devices, consider the following tips:

1. Use High-Resolution Images: Aim for a minimum of 1080 pixels wide by 608 pixels tall for the best quality.

2. Design for the Center: Facebook may crop the top and bottom of your cover photo, so design your image with the most important content in the center.

3. Keep Text to a Minimum: Text at the top or bottom of your cover photo might get cropped on different devices.

4. Test on Different Devices: Preview your cover photo on both desktop and mobile to ensure it looks good on all platforms.

5. Update Regularly: Consider changing your cover photo periodically to keep your Facebook profile fresh and engaging.

Remember that Facebook's cover photo specifications can change over time, so it's a good idea to check the latest guidelines on the Facebook Help Center or directly within the Facebook platform before uploading a new cover photo.
