Hashtag and Character Counter
Each platform sets its own maximum length, and the same post can fit on one and fail on another. Counting by hand also misses details: an emoji can take more than one character in some counts, and X counts every link as 23 characters regardless of its real length.
Everything above runs in your browser and saves to this device only. Paste or write a post, and the counts and the platform chart update as you type.
How it works
Characters are counted as the reader sees them, so an emoji or an accented letter counts once. X’s count replaces each link with 23 characters.
Hashtags are listed, with repeats flagged. Capitalising each word in a multi-word hashtag makes it readable by screen readers.
Frequently Asked Questions
What is the character limit on X?
The character limit on X is 280 characters for a standard post, and every link counts as 23 characters whatever its real length. Paid accounts can post longer.
How many characters can an Instagram caption have?
An Instagram caption can have up to 2,200 characters. Only the first lines show before the caption is cut off, so the key message belongs at the start.
What are the character limits for LinkedIn, TikTok, and Facebook?
LinkedIn posts allow 3,000 characters, TikTok captions 4,000, and Facebook posts 63,206. Limits change, so check each platform's help page before a large campaign.
How many hashtags should I use?
Two to five relevant hashtags usually work better than a long block. Capitalising each word in a multi-word hashtag, such as #BookDirect, makes it readable for screen readers.
Is this Hashtag and Character Counter free?
Yes. The Hashtag and Character Counter is free and opens straight away in any modern browser, including on a phone. Everything you enter is processed in your browser and stays on your device.
