A Telegram group can hold up to two hundred thousand people. Nothing about the interface changes as it grows, which is the good news and also the problem: the same chat that worked for eleven friends is still there at eleven thousand, and it stops working long before the limit.
What scales is the infrastructure. What does not scale is everybody being able to say anything at any time, and Telegram gives you four controls for exactly that.
What you will be able to do
- check_circle Say what changes when a basic group becomes a supergroup.
- check_circle Use permissions, slow mode and the join gate before you need them.
- check_circle Delegate to admins without handing over everything.
- check_circle Decide what new members should be able to see.
Permissions, slow mode and administrators all live in the same settings screen, one tap from the group header.
groups The conversion nobody notices
A small group starts as a basic group. When it grows past a couple of hundred members, or when you turn on something a basic group cannot do — a public link, slow mode, detailed permissions — it converts to a supergroup. The conversion is automatic, permanent and mostly invisible.
One thing does change visibly: in a supergroup the history lives in the cloud rather than being distributed to members as they join, so somebody arriving today can read everything from the beginning. Whether that is a welcome or an exposure depends on the group, and it is a setting you should look at deliberately rather than discover.
Everything else that arrives with a supergroup is a control you do not have to use. The useful discipline is turning them on before the group needs them, because every one of them is harder to introduce after a bad week than before it.
Four things that break, and the control for each
In roughly the order a growing group meets them.
speed Slow mode
how_to_reg The join gate
rule Default permissions
switch_account Admins with narrow rights
A large group is not a big chat. It is a small chat plus four rules, and the rules should be there before the crowd is.
settings Setting a group up to grow
- Open the group, edit, then permissions Everything below is on this screen or one tap from it.
- Decide on history for new members Before anybody new arrives, not after.
- Set slow mode to something short Thirty seconds is invisible to a normal member and fatal to a flooder.
- Turn on join approval Especially if the link is anywhere public.
- Restrict links for ordinary members The single most effective default in a public group.
- Appoint two admins with narrow rights Two, so the group is never waiting for one person.
This page is the controls a growing group needs. The curriculum step goes deeper into the one that matters most: what each admin right actually allows, how to give the least that works, and what the audit log shows you afterwards.
At a glance
