How to Count Characters, Words, Sentences, and Lines Online

TL;DR: Need to count characters, words, or sentences, or analyze your text for repeated words? The Count Characters, Words, Sentences, Lines tool gives you all metrics instantly in real time, with word frequency analysis, custom counts, and stop-word filtering. Everything runs in your browser.

You're writing a meta description and need to stay under 155 characters. Or finishing a 2,000-word essay and want an exact count. Or reviewing a document and wondering which words you overuse. Each of these requires a different tool, unless you have one that does all of them.

TextModifier's Count Characters, Words, Sentences, Lines tool gives you every text metric at once, updates in real time as you type, and runs entirely in your browser.

What the Tool Counts

Paste or type any text and the Total table updates instantly with five metrics:

• Characters: total character count, excluding line breaks
• Words: total word count (supports all languages)
• Sentences: total sentences, detected by terminal punctuation (. ! ?)
• Lines: total line count based on line breaks
• Paragraphs: text blocks separated by blank lines

No buttons to press. The numbers update as you type or paste.

Adjusting How Characters Are Counted

The default character count excludes line break characters but includes spaces. The Count Text options let you change this:

• Do not count spaces: excludes all whitespace
• Do not count HTML tags: strips HTML markup before counting
• Count line breaks as spaces: treats each line break as a single space character

These options affect the character count in the Total table. The word, sentence, line, and paragraph counts adjust for HTML stripping when that option is enabled.

Finding a Specific Word or Phrase

The Custom Count section searches your text for any word or phrase and returns the number of occurrences.

1. Type a word or phrase into the search field
2. The match count appears immediately below
3. Enable Case sensitive to distinguish between uppercase and lowercase matches
4. Enable Match whole word to count only exact word matches, not partial matches within other words

This works for any string: a word, a phrase, a punctuation mark, even an HTML tag. The search matches exact text, not patterns or regex.

Analyzing Word Frequency

Open the Word Frequency section to see every unique word in your text ranked by how often it appears. Each entry shows:

• The word itself
• How many times it occurs
• Its percentage of total words

Use the search field to filter the list to words containing a specific string.

Excluding Stop Words

Enable Exclude stop words to hide common words like "the", "a", "is", and "and" from the frequency table. This surfaces the meaningful, content-carrying words in your text.

The stop word list covers multiple languages, so the filter works regardless of which language your text uses.

Full Unicode Support

Every metric in the tool supports all languages and scripts. Word counting and word frequency use Unicode-aware matching, so text in any language is counted correctly and appears in the frequency table.

The stop word list covers multiple languages to ensure the filter works regardless of which language your text uses.

Real-World Use Cases

Staying Within Character Limits

Social media posts, meta descriptions, SMS messages, and ad copy all have strict character limits. Paste your text and check the character count instantly, with or without spaces, depending on the platform's counting method.

Hitting Word Count Targets

Essays, articles, and reports often require a specific word count. The tool gives you an exact number that updates as you edit, so you know the moment you hit your target.

Improving Writing Quality

The word frequency table reveals overused words at a glance. If "very" appears 47 times in your article, you'll see it immediately. Enable stop word exclusion to focus on content words and spot repetition in your vocabulary.

Analyzing Competitor Content

Paste a competitor's blog post to see their word count, sentence count, and most-used terms. Use this to benchmark your own content length and keyword density.

Counting Code or Data Occurrences

Use Custom Count to find how many times a variable name, function call, or data value appears in a block of text. Case-sensitive mode ensures exact matches.

Privacy and Speed

TextModifier processes everything in your browser. No text is uploaded to a server. No accounts, no tracking, no data storage. Every count updates instantly on your device.
