Telegram channels enable users to broadcast messages to multiple users simultaneously. Like on social media, users need to subscribe to your channel to get access to your content published by one or more administrators. Done! Now youโre 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 itโs recommended to use PNG format to deliver an unpixelated avatar. To edit your name or bio, click the Menu icon and select โManage Channel.โ
