How many people can you add to an iMessages group?

I was curious what the limit was on the number of people you can add to an iMessages group. Assuming everyone was on iMessages (i.e. everyone shows up as blue).

Solution 1:

I read nothing about a limit in the different user guides for iOS devices (e.g. iPhone User Guide [PDF, 17MB]). Because of that I think there is no limit for groups.

Solution 2:

Apple has published on April 03, 2020 a limit of 32 people per group iMessage / Messages / FaceTime. You can have many more groups in the app, just not more than 32 distinct AppleID/iCloud per group.

You can start a Group FaceTime from the FaceTime app or from a group conversation in the Messages app — and you can add up to 32 people.
