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 itβs recommended to use PNG format to deliver an unpixelated avatar. Your posting frequency depends on the topic of your channel. If you have a news channel, itβs OK to publish new content every day (or even every hour). For other industries, stick with 2-3 large posts a week. 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).
