A TikTok character counter checks your text against TikTok’s limits. At the time of writing, captions can be up to 4,000 characters, comments 150, bios 80, usernames 24 and display names 30, and hashtags count toward the caption. For video length, the app records and uploads videos up to 10 minutes for most accounts, and only original videos longer than one minute earn from Creator Rewards.

TikTok character limits and video length at a glance
TikTok limits at the time of writing — they change. If the app won’t accept your text, the app is right.
| What | Limit | Good to know |
|---|---|---|
| Caption | 4,000 characters | Hashtags, @mentions, spaces and line breaks all count. Only the first line or two show before “more”. |
| Comment | 150 characters | Split a longer reply into two comments, or answer with a video reply. |
| Bio | 80 characters | Say what you post and who it’s for. Links typed into the bio text aren’t clickable. |
| Username | 24 characters | Letters, numbers, underscores and periods. It can’t end with a period. |
| Display name | 30 characters | The bold name on your profile. It can differ from your @username. |
| Video in the app | Up to 10 minutes for most accounts | The app records and uploads videos up to 10 minutes for most accounts; longer uploads have been rolling out — check your upload screen. |
| Creator Rewards | Longer than 1 minute | Only original videos longer than one minute earn from the Creator Rewards Program. |
How long should a TikTok be?
There’s no single right length. These are common ranges creators use, not TikTok rules. Keep a video only as long as it holds attention, then check watch time in your analytics.
| Video type | Common length | Why it works |
|---|---|---|
| Sales demo | 20–45 seconds | Show the product working fast, then the offer, before attention drops. |
| Tutorial | 1–3 minutes | Enough time for each step without rushing, and over the one-minute Creator Rewards line. |
| Storytime | 1–2 minutes | Room for the setup, the twist and the payoff. |

How long should a TikTok be?
There’s no single right length. Common practice is 20–45 seconds for a sales demo, 1–3 minutes for a tutorial and 1–2 minutes for a storytime. If you want to earn from Creator Rewards, go over one minute. Keep a video only as long as it holds attention, and check watch time in your analytics.
What is TikTok’s caption character limit?
TikTok captions can be up to 4,000 characters at the time of writing. Only the first line or two show before “more”, so put your hook and main keyword first. Limits change, so if a post won’t go through, check the caption box in the app.
What is the TikTok comment character limit?
Comments can be up to 150 characters at the time of writing. Spaces and @mentions count too. Use the Comment tab above to check a reply before you post it, and split a longer reply into two comments.
Do hashtags count toward the caption limit?
Yes. Hashtags are part of the caption text, so every # and letter counts toward the 4,000 characters, and so do @mentions, spaces and line breaks.
Is this TikTok character counter free?
Yes. It’s free and unlimited with no sign-up. Counting happens in your browser, so nothing you type is sent or saved.
