Frequently asked questions
How does X (Twitter) count URLs?
X shortens all URLs to 23 characters regardless of original length. The counter shows your raw character count — factor in URL shortening manually when your post contains links.
What is Instagram's visible caption length?
Instagram shows the first 125 characters before a 'more' link. The full caption can be up to 2,200 characters. The card highlights when you exceed the preview threshold.
Does LinkedIn have different limits for posts vs. articles?
This tool counts characters for LinkedIn Posts (3,000 char limit). LinkedIn Articles have a much higher limit and are managed in a separate editor.
