You can use Mentimeter with any audience size, regardless of which plan type you have. This is also true for Free users.
Quiz type slides have a limit of 2,000 participants, but there is no limit for other slide types. For performance reasons, we do have some requirements for presenting with large audiences.
If you're planning to host a presentation with more than 10,000 participants, please email us at email@example.com at least 2 days in advance with the following information:
Date and time of your presentation (start and end time, including time zone)
Max estimated audience size
Link to your presentation (how to share presentation link)
Approximate location of your audience (if known, just the continent is enough)
The quiz question type has a capacity of 2,000 participants. All other question types work perfectly up to several thousand participants so we recommend using other slide types for larger audiences (such as Multiple Choice or Open Ended slides).

Some pro tips when you are using Mentimeter with a large audience:
If the audience is in one location, such as a large venue, try not to give all participants access to the WiFi network. The mobile network is often better dimensioned than the venue WiFi hotspot. Also check with the venue's technical agent to see if the WiFi can handle that many connections simultaneously.
If you are relying on the venue WiFi, connect the laptop that is used to present Mentimeter to a wired connection, so as to avoid any issues due to potential overload on the WiFi. If there is no wired connection available, we recommend that you use a USB-dongle and connect to the 4G network.
