How to set up a Telegram channel from scratch: Avatars, bios, pinned posts, and your first 10 uploads
A hands-on guide for founders and marketers to build a high-converting Telegram channel, backed by our experience running a Telegram channel network.
When you launch on Telegram, you are playing by different rules. There is no algorithmic feed deciding who sees your content; every single post lands directly in your subscribers' chat list. In our practice, we have seen that a new visitor decides whether to hit 'Join' or leave within just five seconds. If your channel looks messy, empty, or confusing, you are wasting your marketing budget from day one.
- Start with a public channel. You need a clean t.me link and deep analytics tracking via tools like TGStat or Telemetr.
- Keep your bio under 150 characters. On mobile screens, long paragraphs get cut off, hiding your pitch and contact links.
- Treat your pinned post as a landing page. Use it to introduce yourself, explain the problems you solve, and link your best foundational guides.
- Never drive traffic to an empty channel. Publish your first 10 posts beforehand so visitors can immediately see the value of staying.
The absolute technical essentials
Before you write a single word, you need to understand the platform's hard limits. We always start with a Public Channel. Private channels might seem exclusive, but they prevent you from securing a custom t.me link and make it much harder to track performance on TGStat. Your channel bio maxes out at 255 characters, but we recommend keeping it under 150 characters so it fits perfectly on mobile screens without getting truncated. A standard text post can hold up to 4,096 characters, while images with captions are capped at 1,024 characters unless you have Premium formatting.
- Type: Public Channel (essential for custom t.me links and open search)
- Avatar size: At least 512 x 512 px, optimized for a circular crop
- Images: 1280 x 720 px (16:9) or 1280 x 1280 px (1:1 square)
- Post limits: 4,096 characters for text-only, 1,024 for standard image captions
Designing an avatar that stands out in a crowded chat list
Your avatar is competing with personal chats, news channels, and family group chats in a user's inbox. Avoid complex, text-heavy logos because they shrink into an unreadable blur on mobile screens. We suggest using a high-contrast logo or a professional, friendly headshot of the founder. When naming the channel, combine your brand name with your main topic (for example, 'Slaboda | AI for Business'). This simple trick makes your channel searchable when users look up keywords inside Telegram.
- Stick to clean, high-contrast images that look sharp at 40 x 40 px
- Skip small text inside the avatar; nobody can read it on mobile
- Add your core keyword to your title to capture organic in-app search traffic
| Post Range | Content Focus | Objective |
|---|---|---|
| Posts 1-3 | Core frameworks & deep dives | Establish expertise and set the tone |
| Posts 4-6 | Real-world case studies & metrics | Build trust with tangible proof of work |
| Posts 7-8 | Interactive polls & industry debates | Get readers talking and voting |
| Posts 9-10 | Tool stacks & checklists | Drive forwards to other chats and saves |
Writing a bio that converts visitors into subscribers
Your bio has one job: answer 'Why should I care?' in under five seconds. You have 255 characters to explain who you are, what value you offer, and how to contact you. In our experience, the best bios use simple line breaks to separate ideas. Do not forget to include a clear call-to-action (CTA) pointing to your website or a direct Telegram username for business inquiries.
- Define your exact audience and what they will learn here
- Keep it short and use line breaks instead of walls of text
- Add a direct contact handle (@username) for partnerships or leads
Using your pinned post as a landing page
Since Telegram doesn't have a website-style menu, your pinned post is your ultimate navigation hub. When a new user arrives, they should click your pinned post and instantly understand your expertise. We use pinned posts to introduce ourselves, explain the core promise, establish credibility, and link to foundational guides. Use Telegram's internal message links (t.me/channel/123) to build an easy table of contents. Remember to remind readers to unmute your channel so they don't miss your next update.
- Introduce yourself and explain the specific problems you solve
- Link your best foundational guides using internal Telegram message links
- Add a clear call to action to turn on notifications
- Remind readers to unmute notifications so they see your posts
The first 10 posts: Building instant authority
If you invite people to an empty room, they will leave immediately. Before you buy a single ad or share your link, publish exactly 10 high-quality posts. This gives new arrivals enough content to scroll through, proving that you know what you are talking about. We recommend mixing up your formats: break down a framework, share a real-world case study with actual numbers, run a poll, and offer a practical checklist that readers can save or share.
- Posts 1 to 3: Practical breakdowns of your main frameworks or business methods
- Posts 4 to 6: Case studies showing real workflows, tools used, and results
- Posts 7 and 8: Interactive polls to engage your readers right away
- Posts 9 and 10: Highly shareable resource lists, templates, or tool stacks
Realistic benchmarks to measure your progress
Do not let vanity metrics fool you. In our experience running channels, a healthy channel usually sees a 20% to 40% view rate (ERR or Engagement Rate by Views on TGStat) within the first 24 hours. Keep in mind that only 10% to 25% of your subscribers will keep notifications unmuted—that is completely normal for the platform. If you start running Telegram Ads or buying promotions in other channels, keep an eye on subscriber acquisition costs. In our practice, B2B tech and finance niches often see costs ranging from $1.50 to over $5.00 per subscriber, depending on your targeting and country. Note that ad laws and platform rules are constantly shifting, so check current guidelines before launching campaigns.
- Aim for a 20% to 40% ERR (view rate) in the first 24 hours
- Expect 10% to 25% of your audience to keep your channel unmuted
- Prepare for B2B subscriber costs of $1.50 to $5.00+ when running paid ads
Step by step
Choose 'Public' during setup so you can secure your custom t.me link. Upload a high-contrast, circular 512 x 512 px avatar.
Write a description under 150 characters. Clearly state who you are, what value you provide, and add a direct contact handle.
Draft a welcoming pinned post. Introduce your background, link to your best content, and prompt new users to unmute notifications.
Upload exactly 10 posts covering methods, case studies, polls, and tools before inviting anyone to join.
Common mistakes
Buying cheap bots will ruin your channel. It tanks your engagement rate (ERR), alerts real users that your numbers are fake, and can get your channel flagged or banned by Telegram. Build your audience organically.
Most of your readers are on mobile. If you publish massive, unbroken blocks of text, people will just scroll past. Keep paragraphs short, use bold headers, and leave plenty of empty space.
If you do not link a discussion group or allow comments, you miss out on building a community. Create a feedback loop so readers can ask questions and discuss your posts.

Should I make my new Telegram channel public or private?
We always recommend starting with a public channel. This is the only way to claim a custom t.me link and track your performance properly using third-party analytics tools like TGStat and Telemetr.
How long should my channel description be?
While Telegram allows up to 255 characters, try to keep your bio under 150 characters. This prevents mobile devices from cutting off your contact links or call-to-action.
What is a healthy view rate for a Telegram channel?
In our experience, a healthy and active channel generally maintains a 24-hour view rate (ERR) between 20% and 40%.
How many posts should I prepare before launching?
We suggest publishing exactly 10 high-quality posts before you start promoting your channel. This ensures that new visitors have enough valuable content to read and share.
What is the recommended avatar size for Telegram?
Upload a square image that is at least 512 by 512 pixels. Keep your face or brand logo centered, because Telegram will crop it into a circle.
