How Do I Change the Media Size in WordPress Max?

To change the maximum upload file size in a WordPress Multisite network (often referred to as WordPress Max), you'll need to adjust the network settings. Here's how:

1. Access the Network Admin Dashboard: In your WordPress installation, go to My Sites -> Network Admin -> Dashboard. This is different from the regular WordPress dashboard for a single site.

2. Navigate to Network Settings: On the Network Admin Dashboard, click on Settings -> Network Settings.

3. Locate the "Max upload file size" Field: Scroll down the Network Settings page until you find the field labeled "Max upload file size".

4. Update the Value: Enter the desired maximum upload file size in kilobytes (KB). For example, to set it to 64 MB, you would enter 65536 (64 MB * 1024 KB/MB).

5. Save Changes: Scroll to the bottom of the page and click the Save Changes button to apply the new maximum upload file size.

Important Considerations:

• Server Limits: This setting only affects the WordPress limit. Your web server (e.g., Apache, Nginx) and PHP configuration also have limits on upload file sizes. You may need to adjust these separately for the change to take full effect. Common PHP settings to adjust are upload_max_filesize, post_max_size, and memory_limit in your php.ini file. Contact your hosting provider for assistance with server-side adjustments if needed.
• User Experience: Setting an extremely high limit might be tempting, but consider the impact on your server's performance. Large uploads can consume significant resources.
• Security: Be mindful of security when increasing upload limits. Ensure you have appropriate security measures in place to protect against malicious uploads.

Changing the "Max upload file size" in Network Settings is the primary way to manage media size limits across your WordPress Multisite network. Remember to coordinate with your hosting provider to adjust server-side settings if needed for optimal functionality.
