The main design elements of your Telegram channel include a name, bio (brief description), and avatar. Your bio should be: Done! Now you’re the proud owner of a Telegram channel. The next step is to set up and customize your channel. 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. To view your bio, click the Menu icon and select “View channel info.” 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.
