Frequently asked questions
Common questions about character limits, SMS sizing, and how this free text character counter works.
What does this message character counter measure?
This tool measures total characters, words, sentences, paragraphs, reading time, and SMS segments for the text you enter. It also compares your text against common platform limits so you can see whether your draft fits before you send or post it.
Why can SMS drop from 160 characters to 70 characters?
SMS uses a compact GSM-7 encoding for basic Latin characters, which allows up to 160 characters in a single segment. If your text includes Unicode characters such as emoji, smart quotes, or many non-Latin symbols, the limit drops to 70 characters per segment.
Do spaces, punctuation, and line breaks count as characters?
Yes. Spaces, punctuation marks, and line breaks are counted as characters because platforms and SMS systems count them too. Some GSM-7 extended characters also consume two SMS units even though they appear as one visible character.
Which platform limits can I check with this tool?
The live limit bars compare your draft against Twitter/X, SMS, WhatsApp status, Instagram bio, LinkedIn post, and Facebook post limits. These comparisons are useful for social captions, support replies, and short marketing copy.
