| TikTok caption | 2,200 | — | |
| Facebook post | 63,206 | — | Practically unlimited, but engagement drops past ~80 characters |
| Threads post | 500 | — | |

How it works
Paste or type your post
Drop your draft into the box — nothing needs to be formatted a specific way first.
See your count update live
Character and word counts update instantly as you type, no button to press.
Check every platform at once
A table shows whether your post fits X, LinkedIn, Instagram, TikTok, Facebook, Threads, and YouTube — all at the same time.
Why use this tool
Every major platform in one table
No more checking one platform's limit, switching tabs, then checking the next — see all seven at once.
Shows exactly how far over you are
Instead of just "too long," it tells you the exact number of characters to cut.
Includes truncation notes, not just hard limits
Some platforms technically allow more than what actually displays — the notes column flags where visual truncation kicks in earlier than the real limit.
Free, no signup, no limit
Check as many drafts as you want with no account and nothing to install.
Nothing you type is stored
The count happens entirely in your browser — no draft is ever sent to a server.
Word count included too
Character limits aren't the only thing that matters for readability — word count is shown alongside for a fuller picture.
When you'd actually use this
Writing a cross-posted announcement
Draft once and check it fits every platform you're posting to before splitting it into platform-specific versions.
Trimming an X (Twitter) post
See exactly how many characters over 280 you are so you know how much to cut, not just that it's too long.
Writing an SEO meta description
Check against Google's ~160 character truncation point before publishing a blog post or landing page.
Planning a LinkedIn post's opening line
LinkedIn truncates with "see more" around 210 characters — check your hook fits before that cutoff.
Writing an Instagram caption
See how much of a long caption will show before "more" truncates it in the feed.
Tips for best results
- 1Front-load your strongest line — most platforms truncate before the full post is visible, so the first sentence matters more than the last.
- 2Don't just aim to stay under the hard limit — check the truncation note, since several platforms visually cut off posts well before the actual character cap.
- 3If a post is close to a limit, try cutting filler words first ("really," "very," "just") before cutting actual content.
- 4Re-check after adding hashtags or a link — both count toward the character limit on most platforms.
Frequently asked questions
What is the X (Twitter) character limit?
280 characters for most accounts; X Premium subscribers get up to 25,000 characters for long-form posts.
How long can a LinkedIn post be before it gets truncated?
LinkedIn allows up to 3,000 characters, but the post is visually truncated with a "see more" link after roughly the first 210 characters in feed, so the opening line matters most.
Does going over Instagram's caption limit break the post?
No — Instagram allows up to 2,200 characters and simply won't accept more; the practical concern is that only about the first 125 characters show before "more," not a hard cutoff.
Is this tool free and does it save what I type?
Yes, it's free with no signup, and nothing you type is stored or sent anywhere — the count happens entirely in your browser.
What's the character limit for a YouTube title?
100 characters, though titles display fully only up to roughly 60-70 characters in search results and suggested video lists before truncating.
Do emojis count as one character or more?
It varies by platform's counting method — many platforms count certain emojis as two characters, and this tool counts by raw character length, so treat the count as a close estimate for posts using many emojis.
Is there a minimum length I should aim for, not just a maximum?
There's no universal minimum, but very short posts often get less algorithmic reach on platforms like LinkedIn and Instagram, which tend to favor posts substantial enough to hold a reader's attention for a few seconds.
Does a link count against my character limit?
On most platforms, yes — a full URL counts toward the limit, though some platforms (like X) internally shorten links to a fixed character count regardless of the original URL's length.
