A guide, not a rule
Characters are counted as you see them (an emoji with skin tone is one). Your text stays in this tab and is cleared when you close it.
How to use it

Details
- 文字数
- Characters excluding line breaks; full-width and half-width characters each count as one, spaces included
- 空白除く
- Excluding all spaces, full-width (全角) and half-width (半角)
- 原稿用紙
- Characters ÷ 400. A rough guide: real manuscript paper also counts blank squares at paragraph starts and line ends
- X
- Japanese characters count as 2 of the 280 limit, so about 140 Japanese characters fit in one post
Questions
Is anything I type sent anywhere?
No. The calculation runs in this page with JavaScript; dates, text and numbers are never uploaded or stored on a server.
文字数に改行やスペースは含まれますか? Are line breaks and spaces counted?
最初の数字は改行を除き、スペースは含みます。スペースも除く数は「空白除く」に表示されます。The main count excludes line breaks but includes spaces; 'without spaces' removes both.
Why can I only write about 140 characters on X?
X counts each Japanese, Chinese or Korean character as 2 toward its 280 limit, so 140 full-width characters fill a post. Half-width letters and numbers count as 1.
Is the 原稿用紙 figure exact?
No. On real genkō yōshi, a new paragraph starts with an empty square and lines end early, so the page count is usually a little higher than characters ÷ 400.
Why is the word count different?
Japanese has no spaces between words, so the word count uses a dictionary-based split from the browser. Japanese writing is normally measured in characters, which is why that is shown first.
