Free Live Word, Character, Sentence & Reading-Time Counter

WordToolbox is a live character, word, sentence and reading-time counter. You paste raw text into the box above and it immediately reports word count, character count with and without spaces, sentence count, paragraph count, line count, unique words, average sentence length and estimated reading and speaking time.

It exists for one problem: you need to know how long a piece of text is without opening a heavy word processor, creating an account, or waiting for a page to submit. Everything runs as JavaScript inside your own browser, which is why the numbers appear as fast as you can type.

Who it is for

Built primarily for content writers and copywriters working to word and character budgets, and used daily by students checking assignment limits, editors trimming copy, social media managers fitting posts into platform limits, bloggers tracking SEO article length, and programmers inspecting string lengths.

Searches for a word counter online almost always come from a length target: a 1,500-word essay, an 800-word blog brief, a 250-word abstract, a 60-second script. Searches for a character counter online come from a hard technical ceiling instead: 280 characters on X, 150 for a meta description, 2,200 on an Instagram caption, 30 for a Google Ads headline. WordToolbox reports both at once, so you never have to paste the same draft into two different sites.

Which number should you trust for your task?

Why the two counts disagree

English prose averages roughly 5.1 letters per word plus one space, so about 6 characters per word. A 500-word section lands near 3,000 characters with spaces and near 2,550 without. That estimate breaks down for technical writing, German compounds, URLs and emoji, which is exactly why the counter measures your actual text rather than multiplying an average.

Character counting here is grapheme-based: an emoji or an accented character counts as one character, matching what a reader sees, though some platforms bill emoji as two units in their own limits. If invisible or zero-width characters are inflating a count, the Unicode and hidden character reference explains what to look for.

Hitting a target instead of just measuring it

When you are short or long against a word limit, the fix is editorial rather than mechanical — see how to meet essay word counts without fluff or padding. For platform character ceilings, the character limit checker for social media and ads lists the current limits per network.

More detail lives on the how it works page and in the reading and speaking speed reference.

• Maximum 500,000 characters per pass (roughly 80,000 words). Longer text triggers a warning rather than silent truncation.
• Plain text only. There is no file upload: .docx and .pdf files must be opened and their text pasted in.
• Reading and speaking times are estimates based on fixed averages. Technical or unfamiliar material reads slower.
• Sentence detection is punctuation-based. Abbreviations such as “e.g.” can occasionally split a sentence in two.
• No rate limits and no accounts, because no request is ever sent to a server.
