wp_is_large_network( string $using = 'sites', int|null $network_id = null )

Whether or not we have a large network.


The default criteria for a large network is either more than 10,000 users or more than 10,000 sites. Plugins can alter this criteria using the ‘wp_is_large_network’ filter.



(string) (Optional) 'sites or 'users'. Default is 'sites'.

Default value: 'sites'


(int|null) (Optional) ID of the network. Default is the current network.

Default value: null


(bool) True if the network meets the criteria for large. False otherwise.
