How to use the Social Media Character Counter
Type or paste your caption, post, title or bio.
Pick a field type tab, such as Post or caption, Title or Bio, to see the right limits.
Check each platform row: the bar shows the hard limit and the marker shows the "See more" cut-off.
Trim the text until the platforms you need are green, then copy it.
Examples
A caption of 160 characters
Fits everywhere, but is cut off with "more" after about 125 characters on Instagram
Character limits by platform
| Platform | Field | Limit | Shown before "more" |
|---|---|---|---|
| Caption | 2,200 | ~125 | |
| Bio | 150 | – | |
| Post | 3,000 | ~210 | |
| Headline | 220 | – | |
| YouTube | Video title | 100 | ~70 in search |
| YouTube | Description | 5,000 | ~150 |
| TikTok | Caption | 4,000 | ~100 |
| Post | 63,206 | ~480 | |

| Threads | Post | 500 | – |
| Pin title | 100 | ~40 | |
| Pin description | 500 | ~50 |
Platforms change limits and truncation points regularly and they vary by device, so treat the "Shown before more" column as a guide.
Why the visible length matters more than the limit
Most limits are generous, but very few people tap "See more". On Instagram, LinkedIn and TikTok, the first one or two lines do almost all the work: they need to hook the reader, state the point and, if you are using one, include the call to action. Write the full post, then make sure the opening line would still make sense if it were all anyone read.
For YouTube titles and Pinterest pins, the visible part in search results is what drives clicks, so put the most important words first.
How characters are counted
Each emoji, accented letter or symbol counts as one character here, which matches how most platforms count. Line breaks and spaces count too. X is the exception: it counts emoji as two and every link as 23, so the X row uses those rules. For a detailed X breakdown, use the Twitter Character Counter.
Hashtags and mentions count towards the total on every platform.
Tips for multi-platform posts
- Write for the shortest platform first, then add detail for the longer ones.
- Put hashtags at the end or in a first comment so they do not crowd the opening line.
- Avoid long URLs on Instagram and TikTok captions, where links are not clickable.
- Use line breaks for scannable LinkedIn and Facebook posts.

Bios, titles and descriptions
Character limits apply to more than posts. Profile bios are short everywhere: 150 characters on Instagram and 80 on TikTok, so every word should say who you are and why people should follow. YouTube titles allow 100 characters, but the first 60 or so do the work in search. Pinterest pin titles show only about 40 characters in the feed. Switch the field type at the top of the tool to see the limits that apply to what you are writing.
