Frequently Asked Questions
What is an online character counter?
An online character counter is a free web tool that instantly counts the number of characters in any text you type or paste. CharCounter.online counts characters with spaces, characters without spaces, words, sentences, paragraphs, and lines — all in real time, with no sign-up required.
How do I count characters online for free?
Simply paste or type your text into the box above. Our free char counter automatically displays your character count, word count, and social media limits instantly. No download, no sign-up, no cost — completely free.
How do I count characters without spaces?
The "Characters (no spaces)" counter automatically strips all whitespace and shows the raw character count. This is useful for platforms that ignore spaces in their limits.
What is a word checker tool?
A word checker counts the total number of words in a text. Our tool works as both a char counter and word checker simultaneously — you see both counts update live as you type.
How is reading time calculated?
Reading time is estimated at 200 words per minute — the average adult reading speed for online content. The result is always rounded up to the nearest minute.
What is the Flesch Reading Ease score?
The Flesch Reading Ease score rates text on a scale from 0 to 100. Higher scores mean easier reading. A score of 60–70 is considered standard for general audiences. Academic and technical content typically scores below 30, while simple conversational text scores above 80.
Does this char counter store my text?
No. All processing happens entirely in your browser. Your text is never sent to any server and is not stored or logged anywhere.
What is the Twitter/X character limit?
Standard X (Twitter) accounts have a 280-character limit per tweet. Twitter Blue / X Premium subscribers can post longer content — up to 25,000 characters.
What is char length and why does it matter?
Char length refers to the total number of characters in a string of text, including letters, numbers, spaces, punctuation, and symbols. It matters for social media posts, SEO meta descriptions, SMS messages, and any platform with a character limit.
What is keyword density and how is it calculated?
Keyword density is the percentage of times a word appears in your text relative to the total word count. Our tool shows the top 8 most frequent meaningful words, helping you avoid keyword stuffing and maintain natural writing flow.
Can I set a custom character limit?
Yes. Use the "Custom Limit" field to enter any number and get a live progress bar for that exact limit. This is useful for form fields, database columns, or any platform not listed in the social media section.
Are there keyboard shortcuts?
Yes — Ctrl+Shift+C copies your text, Ctrl+Shift+X clears the textarea, and Ctrl+Shift+S copies your stats to the clipboard. All shortcuts work on Windows and Linux (use Cmd on Mac).
