How to use & tips
Essays, application forms, blog posts and social updates all come with limits, and "how many characters do I have left?" is a common question. This tool counts your text in real time and shows characters with and without spaces, words, lines, paragraphs and UTF-8 bytes at a glance.
How to use it
Just type or paste text into the box above; the counts update as you type. Uncheck "Include line breaks in the count" to exclude line breaks. Because tools count differently, match the count you show (for example, with or without spaces) to your destination's requirement.
Common limits
An X (Twitter) post allows 280 characters, and Japanese manuscript paper uses 400 characters per sheet. For form limits such as "within 400 characters," this tool lets you check both the with-spaces and no-spaces values. Full-width, half-width and emoji each count as one code point.
When it helps
Use it to check submission limits, trim social posts, or measure the size of a translation or transcript. Since nothing is uploaded, you can safely paste unpublished drafts.
Frequently asked questions
How are characters counted?+
Full-width and half-width characters are treated the same, and each kanji, letter, symbol or emoji counts as one character. Spaces and line breaks can be toggled.
Are spaces and line breaks included in the count?+
Whether line breaks are counted is controlled by the "Include line breaks in the count" checkbox.
How is the manuscript page count calculated?+
Real manuscript paper varies with how the grid is used, so treat it as an approximation.
Is the text I enter sent anywhere?+
You can safely use it for unpublished drafts or text containing personal information.
Why does the count differ from Microsoft Word?+
This tool counts by code point, so it can differ from word-based counts or tools that handle spaces differently. Always confirm against your destination's rule.
・Characters = number of Unicode code points in the input (equivalent to
Array.from(str).length). Full-width, half-width and emoji each count as one.・Words = tokens separated by whitespace (Latin-style word counting).
・Bytes = length of the UTF-8 encoding (equivalent to
TextEncoder).・Based on the Unicode standard (The Unicode Consortium) and the Japanese 400-character manuscript convention.
