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. Today, we will address Telegram channels and how to use them for maximum benefit. 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. Your posting frequency depends on the topic of your channel. If you have a news channel, it’s OK to publish new content every day (or even every hour). For other industries, stick with 2-3 large posts a week. But a Telegram statement also said: "Any requests related to political censorship or limiting human rights such as the rights to free speech or assembly are not and will not be considered."
