Why Character Limits Matter
Posting content that exceeds platform character limits either prevents submission entirely or causes the platform to truncate your text — cutting off your call to action, your hashtags, or the most important part of your message. Knowing limits in advance lets you craft posts that fit perfectly.

Count Characters Before Posting
Use our Character Counter to count characters and words in real time before posting. The tool shows both character count and word count, and you can set a custom limit to match your target platform. It also counts emojis correctly (some emojis count as 2 characters on Twitter).
