A 400-character caption on YouTube
YouTube shows about the first 157 characters before "…more", so 243 of the 400 are hidden until someone taps. Put the hook in those first 157.
YouTube bio generator
This YouTube bio generator turns a role or niche and a value-proposition keyword into a set of ready-to-edit YouTube bio suggestions — built from YouTube-specific templates, not AI-written. YouTube channel About descriptions allow up to 1,000 characters, though only roughly the first 150 show in search results and channel previews. The suggestions are written keyword-first since it doubles as search copy, and can run to a few sentences rather than a short tagline. Pick one, tweak the wording to sound like you, and paste it into your profile.
Fill in both fields above to see bio suggestions.
How do you use the YouTube bio generator?
- Type your role or niche. Enter a short phrase for what you do — a job title, a niche or a business type all work.
- Type your value proposition. Enter the one thing you want a reader to know you help with or focus on.
- Review the suggested bios. Each suggestion applies your role and value proposition to a different YouTube-style bio template.
- Copy one you like. Click a suggestion to copy it, then edit it to sound like you before you publish it.
- Paste it into your YouTube profile. Open your YouTube profile’s edit view and paste the bio into the field it belongs in.
What are the YouTube rules to know?

|---|---|
| How length is counted | As you see it: one emoji or accented letter counts as one character |
| Hashtags | Up to 60 per post; extras are flagged before publishing |
| Where the caption is cut off in the feed | About 157 characters before "…more", so lead with the point |
| Text-only posts | Not allowed: every post needs an image or video |
| Links in the text | No link-preview card |
| First comment | Supported: SkedCast can post a first comment right after publishing |
| Feed crop | 16:9 in the feed preview |
| Images | Not published by SkedCast to this platform |

YouTube bio generator FAQ
- What is YouTube’s bio character limit?
- YouTube channel About descriptions allow up to 1,000 characters, though only roughly the first 150 show in search results and channel previews. It is worth checking your own profile editor too, since platforms adjust these numbers occasionally.
- Is this a separate generator built just for YouTube?
- Yes — the templates here are written specifically for how YouTube bios read (written keyword-first since it doubles as search copy, and can run to a few sentences rather than a short tagline.), unlike our general bio generator, which is platform-agnostic.
- Can I post text only on YouTube?
- No. Every YouTube post needs at least one image or video; the caption rides along with the media.
- Will YouTube cut off a long caption?
- In the feed, yes: YouTube shows roughly the first 157 characters and hides the rest behind "…more", so put the hook and any call to action first.
- How many hashtags can a YouTube post have?
- SkedCast flags anything over 60 hashtags on a YouTube post before it publishes, so a post never goes out with tags YouTube would drop.
- What happens to a link in a YouTube post?
- The link counts at its real length, and YouTube shows no link-preview card for it.
