What's the main difference between a Telegram group and a channel?

Groups are for conversation — all members can chat. Channels are for broadcast — only admins post and subscribers read, with no practical subscriber limit.

How many members can a Telegram group have?

Up to 200,000. If you need more people than that, or you mostly broadcast instead of conversing, a channel is the right tool.

Can subscribers in a channel talk to each other?

Not in the channel itself — but if admins enable comments, Telegram creates a linked discussion group where each post gets its own comment thread.

Do bots work in both groups and channels?

Yes. In groups a bot joins as a participant and can react to messages (e.g. NudgeRemindBot handling /remind in the chat). In channels a bot must be an admin to post to subscribers.

Telegram Group vs Channel: Which One Do You Actually Need?

Telegram has two ways to gather people, and picking the wrong one is the most common setup mistake. A group is a conversation: every member can send messages, reply, react, and see everyone else. A channel is a broadcast: only admins post, subscribers just read, and the subscriber count is effectively unlimited.

The limits tell the story. Telegram groups cap at 200,000 members — enormous for a chat, but finite. Channels have no practical subscriber cap and each post can reach every subscriber with a notification. Conversely, a channel where nobody can talk feels cold for a friends' chat; a 50,000-member group where everyone can post is unusable noise.

Bots work in both, but differently. In a group, a bot is a participant: it can see messages, respond to commands, and manage the chat. In a channel, a bot (added as an admin) can post scheduled content to subscribers. This guide covers when each fits, and where a bot earns its place in each.

Steps

Ask: should members talk to each other?. If yes — a friends' chat, a team, a class discussing homework, a game squad — you want a group. If most people should only receive updates (news, announcements, deals, a class schedule), you want a channel.
Create the right one. In Telegram: New Group for conversation, New Channel for broadcast. Channels get a public @username (a searchable t.me link) and a subscriber list; groups get member chat and admin permissions.
Set permissions to match your intent. In a group, admins can restrict new members to read-only or slow mode — a useful middle ground. In a channel, decide whether to allow public comments (which actually creates a linked discussion group behind the scenes).
Add a bot where it helps. In a group, add a bot as a member: for example NudgeRemindBot can drop reminders into the chat with /remind (free tier: 5 active reminders). In a channel, add the bot as an admin so it can post — a reminder about a live event reaches every subscriber.
Consider using both. The classic pattern is a channel for announcements plus a linked group for discussion — Telegram can link a discussion group to a channel so every post gets a comment thread. Big communities almost always end up here.

Good to know

Groups: up to 200,000 members, everyone can post by default, full admin controls (permissions, slow mode, bans), and message history is a real conversation you can search and reply to.
Channels: effectively unlimited subscribers, only admins post, subscribers' identities are hidden from each other, and posts can have view counts, reactions, and inline buttons.
A channel with comments enabled secretly creates a group — the comments thread IS a linked discussion group. So "channel vs group" is not always either/or.
Bots in groups can read and respond to chat; bots in channels need admin rights to post. A reminder bot like NudgeRemindBot works naturally in a group chat where anyone can set a reminder; Pro (150 Stars, ≈ $3) removes the 5-reminder free cap.
Converting is one-way: you can't turn a group into a channel or vice versa. If you realize you picked wrong, create the other type and share the invite link — the same manual migration as leaving any chat.
Public vs private: both groups and channels can be public (searchable, with a t.me username) or private (invite link only). A private group with a rotatable invite link is the Telegram equivalent of a WhatsApp group.
