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. Choose quality over quantity. Remember that one high-quality post is better than five short publications of questionable value. Concise 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. 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.
