Administrators The visual aspect of channels is very critical. In fact, design is the first thing that a potential subscriber pays attention to, even though unconsciously. The optimal dimension of the avatar on Telegram is 512px by 512px, and it’s recommended to use PNG format to deliver an unpixelated avatar. Public channels are public to the internet, regardless of whether or not they are subscribed. A public channel is displayed in search results and has a short address (link). Telegram desktop app: In the upper left corner, click the Menu icon (the one with three lines). Select “New Channel” from the drop-down menu.
