Counting Characters Against Platform Limits
概要
Many platforms enforce strict character limits — tweets, meta descriptions, SMS, bios, and form fields. This counter shows the exact character count as you type so you never get cut off. It runs live in your browser with nothing uploaded.
使い方（ステップ）
- 1
Type or paste text
The character count updates with every keystroke.
- 2
Watch the limit
Compare the count against your platform's maximum.
- 3
Trim to fit
Edit until you are within the allowed length.
仕組み
The tool counts every character you enter, including spaces, punctuation, and line breaks, updating instantly. It can show counts both with and without spaces, since different platforms measure differently. Knowing the precise count lets you trim text to fit a hard limit without guesswork or surprise truncation.
こんなときに使う
Writing a tweet, bio, or caption with a character cap. Fitting a meta description within 160 characters. Keeping an SMS under the single-message limit.
