Frequently Asked Questions
Do emojis count toward the character limit?
Yes, emojis count on most platforms. Twitter counts each emoji as 2 characters due to Unicode encoding, so you may reach the 280-character limit faster than expected.
How are links counted?
Twitter automatically shortens any URL to 23 characters regardless of the original length. Instagram does not support clickable links in captions. This tool counts the raw text as typed.
What does the orange warning mean?
When you use more than 85% of a platform's character limit, the progress bar turns orange as a heads-up. Red means you have already exceeded the limit for that platform.
