Instantly count characters, words, sentences, lines, and paragraphs. Check your text against platform limits for Instagram, Twitter, TikTok, and more.
Platform Limits
Why Character Count Matters on Every Platform
Every social media platform has character limits — but the real limit isn't the technical one. It's the attention limit. Instagram captions get cut off after 125 characters. Twitter shows 280. YouTube titles display about 60 characters before truncation. Knowing your exact count helps you optimize for both the algorithm and human readers.
Platform Character Limits in Detail
Instagram Caption
2200 max
~125 visible before 'more'
Hook in the first 125 chars. Use line breaks after the hook.
TikTok Caption
2200 max
~50 visible by default
Keep captions under 150 characters. Most viewers never expand captions.
Twitter/X Post
280 max
Full post
URLs count as 23 chars. Use 1-2 hashtags max for best engagement.
YouTube Title
100 max
~60 before truncation
Front-load keywords. Keep titles under 60 characters to avoid ellipsis.
YouTube Description
5000 max
First 2 lines (~157 chars)
Keywords in first 2 sentences. Add timestamps after paragraph 2.
LinkedIn Post
3000 max
~140 before 'see more'
Bold first line + line break. Longer posts (1300-2000 chars) perform best.
Word Count vs Character Count
Word count matters for readability and SEO. Character count matters for platform limits. This text counter tracks both, plus sentences, paragraphs, and lines — so you have all the data you need before posting. Use it to trim captions that are too long, or to verify that your YouTube title fits within the visible limit.
Pro workflow: Write your caption in this tool first. Check the character count against the platform limit. Use the caption formatter next to add line breaks, then paste into your post. Planning your text length before posting saves time and prevents awkward truncation.
