A good YouTube bio tells visitors who your channel is for, what they'll get and when new videos go up. Put that in the first line or two, because that's all the channel header shows before "...more". On YouTube, your "bio" is the channel description: up to 1,000 characters, edited in YouTube Studio under Customization > Profile.
YouTube's settings never say "bio"; they say channel description. Here's where it appears, the limits, a template and 14 examples by niche.
Where your YouTube bio shows up
Channel pages no longer have a separate About tab; your description sits in the header at the top of the page. On YouTube's website, that header shows a two-line preview (at the time of writing) followed by "...more", and clicking the preview opens a panel with the full description, your links and channel details. Treat those two lines as the part every visitor sees, and remember phones fit fewer words in them.
To edit your description on a computer:
- Sign in to YouTube Studio.
- In the left menu, choose Customization, then the Profile tab.
- Change the text in the Description box.
- Click Publish.
In the YouTube app, tap your profile picture, then View channel, then Edit under your channel description, and tap Save when done.
The limits that matter
| Field | Limit or rule | Where to change it |
|---|
| Channel description | 1,000 characters | Customization > Profile |
| Handle | 3 to 30 characters for most scripts; letters, numbers and _ - . · (not at either end) | Customization > Profile |
| Channel profile links | Up to 14; the first one shows near the Subscribe button | Customization > Profile |
| Name and handle changes | Twice each within 14 days | Customization > Profile |
| Channel keywords | A separate field, not part of the description | Settings > Channel |
Video descriptions are separate, with a 5,000-character cap; see our guide to the YouTube description character limit.
A fill-in YouTube bio template
Strong channel descriptions answer three questions in order: who is this for, what do they get, and when is the next video?
[Channel name] helps [audience] [get a result] with [type of videos].
New videos every [day or frequency].
[One true proof point: experience, method, or what makes you different.]
[Series, playlists, or topics worth exploring.]
Business inquiries: use the contact email on this channel.
Keep the first line short; long openers get cut off on phones. Our guide on how to write a bio that converts breaks the same idea into value, proof and action.
14 YouTube bio examples by niche
These examples are original, not copied from real channels. Swap in your details and cut any proof point that isn't true for you.
Gaming
Patient guides for impatient gamers. I break down boss fights, builds and hidden quests in Soulslike and roguelike games, so you spend less time stuck and more time playing. New guides every Tuesday and Friday, plus live co-op nights on Sundays.
Tech reviews
Honest reviews of budget phones, earbuds and laptops for people who don't want to overspend. I use every product for at least two weeks before reviewing it, and I'll tell you when the cheaper option is good enough. New reviews every Thursday.
Cooking
Weeknight dinners in 30 minutes or less, made with ingredients from a regular supermarket. Every recipe is tested in a small apartment kitchen with one pan and no fancy gadgets. New recipes every Monday and Thursday.
Fitness
Home workouts for busy parents: 20 minutes, minimal equipment, no gym needed. Follow-along strength, mobility and low-impact cardio for beginners and anyone getting back into it. New workout every Wednesday. Check with a doctor before starting a new routine.
Education: math lessons
Step-by-step math lessons for high school students, from algebra to calculus. Each video works through exam-style problems slowly, with the reasoning spelled out, so you can follow along with a pencil. New lessons every Sunday during the school year.
Education: coding tutorials
Beginner-friendly Python and web development tutorials. Short lessons, full project builds and plain-English explanations of common error messages. Project code is linked in each video description. New tutorial every other Wednesday.
Music
Indie folk songs written in a converted garage. Original music, acoustic covers and the stories behind the lyrics. A new song on the first Friday of every month, with stripped-back live sessions in between. Listen everywhere through the links below.
Vlogging
Slow travel on a small budget. I move to a new city every few months and show what it really costs to live, eat and get around there, mistakes included. New vlog every Saturday.
Personal finance
Plain-English money basics for people in their 20s and 30s: budgeting, paying off debt and how retirement accounts work. New explainer every Tuesday. Everything here is general education, not personal financial advice.
Skip income screenshots and "get rich" promises. YouTube's spam policy treats promoting get-rich-quick investment schemes as a scam.
Beauty
Makeup and skincare for sensitive, acne-prone skin. Drugstore product tests, simple routines and ingredient breakdowns without the jargon. New videos every Wednesday and Sunday. Sponsored videos are always labeled.
Small business: local shop
We're a family-run sourdough bakery showing how we bake, from starter care to shaping and scoring. Behind-the-scenes Shorts during the week and a full bake-along once a month. Opening hours and online orders are in the links.
Small business: service provider
Bookkeeping explained for freelancers and small business owners. Practical walkthroughs of invoicing, expense tracking and quarterly deadlines, each under 10 minutes. New video every Monday. For client work, use the business email listed on this channel.
Faceless and automation channels
Animated explainers about how everyday things work, from traffic lights to tap water. Every episode is researched and scripted by a small team, and sources are listed in each video description. New explainer every Friday.
Say what's original. YouTube's spam policy targets channels that use automated tools or AI to mass-produce near-identical videos, so don't brag about volume.
Kids-safe and family
Simple craft and kitchen-science activities for families with kids ages 4 to 8, using things you already have at home. Written for the grown-ups who choose what their kids watch. New activity every Saturday morning.
YouTube requires creators to say whether their videos are made for kids, and notes that family-friendly content isn't automatically made for kids. Set your audience by who the videos target, not by your bio's tone.
How to write your own: who, what, when
Lead with the viewer. "Recipes for weeknight cooks" says more than "Hi, I'm Sam and I love food."
Add a schedule you can keep. YouTube's own upload-schedule tips stress a consistent, sustainable pace. Promise the schedule you actually run and update the bio when it changes.
Use the words people search, plainly. YouTube's help center says keywords in video descriptions can help people find videos, and its search explainer lists titles, tags, descriptions and video content as relevance signals. It doesn't say how much the channel description counts. Name your topic plainly ("sourdough," "Python," "budget phones"), which helps visitors either way, and treat any search lift as a bonus. Channel keywords have their own field under Settings > Channel.
Put links in the Links section. Add up to 14 channel profile links under Customization > Profile; the first appears near the Subscribe button. YouTube's clickable-links table marks profile links as clickable and URLs in Shorts descriptions as not. For brand deals, fill in the Contact info email.
What to avoid in a YouTube channel description
- Keyword stuffing. YouTube's tags help page says excessive tags in a video description go against its spam, deceptive practices and scams policies. A bio that reads like a keyword list looks just as spammy.
- Misleading claims. The spam policy covers content, metadata and behavior meant to take advantage of viewers, including misleading them. Don't claim partnerships, credentials or "official" status you don't have.
- Sub-for-sub offers. The policy names coordinated sub-for-sub schemes as engagement manipulation. Asking people to subscribe is fine; trading subscriptions isn't.
- A stale schedule. "New videos daily" on a channel that went quiet months ago looks abandoned.
- Filler up front. Greetings and emoji rows waste the preview.
Should you use bold text in your YouTube bio?
YouTube documents built-in bold, italic and strikethrough for video descriptions (see our guide to bold text in YouTube descriptions). Its channel profile help page mentions no formatting for the channel description, and there's no font setting, since YouTube picks the typeface.
You can still paste Unicode "bold" letters, such as those from our YouTube text formatter. They look bold because they're different characters, and that has costs:
- Screen readers. Scope, the UK disability charity, warns that screen readers may skip these characters or announce them one by one, reading a styled letter as "mathematical sans-serif script t".
- Search. Unicode's own chart says these characters are meant for math and that general text should use standard letters. YouTube doesn't say whether its search matches a bold-styled word to the plain word, so keep the words you want to be found for plain.
- Display. Rarer styles can show as empty boxes on older devices.
If you use it, limit it to one short, non-essential phrase, never your handle, email or anything a viewer might copy.
What can go wrong
- The preview cuts you off. Where two lines end depends on screen width, so check your channel on a phone after publishing.
- Name changes have side effects. You can change your channel name and your handle only twice each within 14 days, and a name change removes your verification badge.
- Edits won't save. If a name change fails, YouTube's help page says to delete any channel name translations first. Translated descriptions are separate fields, so update those too.
- AI drafts guess. A generator can't know your schedule or what's true about you.
Draft one with BoldlyType
- Open the YouTube bio generator, describe your channel in a sentence, pick one of eight tones and add an optional call to action. You get five options, and your text is sent to our server to generate them.
- Pick one, then add your real schedule and a true proof point.
- Paste it into Customization > Profile, publish, and check the preview on your phone.
- Need a handle? The YouTube username generator suggests ideas; YouTube tells you if one is taken and offers a similar one.
