Why character limits matter
Every platform trims your words to fit its format. A post that is one character over the X limit will not publish; a meta description that runs long gets cut off mid-sentence in search results; an Instagram caption hides everything after the first couple of lines. Checking the count while you write is far easier than fixing it at the publish button.
The bars above use typical platform limits: 280 characters for an X post, about 155 for a meta description, 2,200 for an Instagram caption and 3,000 for a LinkedIn post. The bar turns amber as you approach a limit and red when you pass it, with the exact remaining characters shown on the right.
Limits change, and some accounts have different allowances — treat these as typical platform limits and check the platform itself before an important campaign.
Frequently asked questions
What is the character limit for X (Twitter)?
A standard X post is typically limited to 280 characters. This counter shows a live bar against that typical limit so you can trim your post before publishing.
How many characters can an Instagram caption have?
Instagram captions can typically run up to 2,200 characters, although only the first line or two is visible before the “more” cut-off, so shorter is usually better.
How long should a meta description be?
Meta descriptions are typically kept to about 150–160 characters so they display in full on search results pages. This tool uses 155 as a typical working limit.
Do spaces count as characters?
On almost every platform, yes — spaces and line breaks count toward the character limit. This page also shows a count without spaces if you need it.
Are these limits guaranteed?
No. Platforms change their limits from time to time and some account types have different allowances, so treat the bars on this page as typical platform limits and check the platform itself before an important post.
Is my text uploaded anywhere?
No. The counting runs entirely in your browser, and nothing you type is sent to a server or stored. The only thing saved on your device is your light or dark theme choice, so the site reopens the way you left it.
