How many people can I invite to an event?
We don't put a limit on the number of guests for events. To help make a positive experience for hosts and guests, you should only invite people you know or people you know are interested in the event. If people you invite aren't responding or are choosing not to join your event, you may be temporarily blocked from inviting more guests. You'll be able to send invitations again once more people join your event.
There are other ways to let people know about your event in addition to sending invitations, like sharing the event on your Timeline or your Page's Timeline. You can also ask your guests to invite people that they know would be interested if you've allowed that in your event's privacy settings.
