See your character count against the limits that matter: posts on X, Instagram captions, LinkedIn posts, YouTube titles, text messages, and Google title and description lengths.
SMS segments explained
A single text message holds 160 characters when it only uses the basic GSM-7 alphabet. One emoji or other special character switches the message to Unicode, which holds only 70 characters per segment. Long messages are split into segments of 153 (GSM-7) or 67 (Unicode) characters. The counter detects this automatically.
Characters, bytes and emoji
Some emoji are made of several Unicode code points. This counter counts each code point once. Bytes are counted in UTF-8, which matters for databases and APIs with byte limits.
Frequently asked questions
How many characters can a tweet have?
Standard accounts on X can post up to 280 characters. Links and some characters are counted differently by X, so treat the counter as a close guide.
Do spaces count as characters?
Yes. Most platforms count spaces. The counter shows both totals.
