Why Do Character Limits Matter?
Every platform has different character limits for posts, captions and bios. Text over the limit is cut off or cannot be posted, while falling far short weakens the message. Enter your text and this tool shows how many characters you have used and how many remain against the major platforms — all on one screen. Any overflow is flagged in red.
Limits Covered
- X (Twitter): 280-character post.
- Instagram: 2,200-character caption, 150-character bio.
- TikTok: 2,200-character caption.
- LinkedIn: 3,000-character post.
- YouTube: 100-character title, 5,000-character description.
- SEO: ~60-character meta title, ~160-character meta description.
Practical Tips
The first 125 characters are what show before the "…more" cutoff on Instagram; put your most striking message there. In X posts, links count as a fixed length. If your SEO meta title exceeds 60 characters, Google truncates it; lead with the most important keyword. This tool counts spaces because the platforms do too.
