There is a hard limit of 50 users in a room, unless you are a Spatial+ user. Users in the space can be made up of a mix of any supported device. If a user attempts to join a space after the space is at capacity, they will be notified that the space is full and will be redirected back to their spaces menu.
Spatial supports a wide variety of devices with different computational needs so device will play a role in how many users can comfortably join. Room performance is influenced by the size and quantity of items in a given room. You may experience performance issues as the number of users and uploaded content increases.
If you wish to share the room to more users we recommend screen recording and streaming from a user in the web app to a service like Teams/Zoom.
If you have any questions regarding user limits please reach out to support@spatial.io
