The limits you are actually counting against
You open a counter for one of three reasons: a ceiling, a floor, or a bill. Ceilings are almost always characters. Floors are almost always words. Bills are words, and they are the least forgiving of the three.
Mixing the units up is the fastest way to miss. A 280-character post on X runs about 45 to 55 words, while a 900-word article is roughly 5,400 to 5,800 characters with spaces. Those figures are not interchangeable, and a counter that shows only one of them is half a tool.
| Constraint | Typical limit | What to watch |
|---|---|---|
| Google meta title | 55 to 60 chars | Truncation is by pixel width, about 580 to 600px |
| Meta description | 155 to 160 chars | Google rewrites these often, but long ones still get cut |
| X (Twitter) post | 280 chars | Links count as 23 characters |
| LinkedIn post | 3,000 chars | Mobile shows about 140 to 210 before "see more" |
| Instagram caption | 2,200 chars | Hashtags count toward the total |
| YouTube title | 100 chars | Search results show about 60 |
| YouTube description | 5,000 chars | Only the first 100 to 150 appear above the fold |
| Email subject line | 30 to 45 chars | Mobile clients cut earlier than desktop |
| Common App essay | 650 words | The form will not accept more |
| Standard blog post | 1,200 to 1,500 words | A floor for depth, not a rule |
Check the number your platform actually enforces. Our walkthrough of word and character counting covers the cases where the two diverge, and that gap is where most last-minute cuts go wrong.
How we compared them
Every tool below processed the same four texts. We checked whether the totals agreed with each other, whether the tool surfaced the limit that mattered without a hunt through menus, and whether it asked for anything in return, meaning an account, an email address, or an upload.
Two behaviours disqualified tools. Anything gating a number behind a signup was dropped, because counting text does not require an identity. Anything loading display ads against the text area was dropped too, since a tool you open twenty times a day should not compete with you for clicks.

1. Glint AI Word & Character Counter
The Glint word counter is one box that updates as you type: words, characters with spaces, characters without spaces, sentences, paragraphs and an estimated reading time.
The useful part is the limit layer. Instead of making you remember that an Instagram caption stops at 2,200 characters or a YouTube description at 5,000, it flags those budgets as you approach them. If you write across several formats in a day, that removes a lot of bookkeeping, which is why it leads this list.
It is honest about its limits. There is no keyword density table, no history, no saved drafts and no goal tracking. Everything runs in the browser, so there is no upload and no account, but the tool also forgets your text the moment you close the tab. The reasoning behind that tradeoff is set out in why a no-signup counter matters.
2. WordCounter.net
WordCounter.net is what most people find first, and it earns that spot by being thorough. Alongside the usual counts it builds a keyword density table showing how often each word appears and its share of the total. For SEO work that is genuinely handy: you can see at a glance whether a phrase appears four times or forty.
The tradeoff is noise. The page is busy, the density table is long even for short text, and there is no awareness of platform limits, so you still need to know a meta title should land near 60 characters. Counting is accurate and matched the other tools here.
3. Character Count Online
Character Count Online does one job cleanly. Paste text and it reports characters with spaces, characters without spaces, words and sentences. The distinguishing feature is a target field: you set the number your platform allows and watch the remaining allowance as you edit.
That small thing matters when the budget is tight. Writing 155 characters is a different exercise from writing 1,500 words, and seeing the room left changes how you approach every sentence. What is missing is everything beyond counting: no reading time, no sentence feedback, no keyword data.
4. Hemingway Editor
Hemingway is a readability tool that happens to count. Paste text and it returns a grade level, highlights hard sentences, adverbs and passive constructions, with word, sentence and paragraph totals in a sidebar.
The value is the highlighting rather than the numbers. A counter tells you that you wrote 1,400 words; Hemingway tells you which of them are buried in a 48-word sentence. The web version is free with no account and the desktop app is a one-time purchase. The honest caveat is that its grade level is a rough proxy, not a verdict, and it will flag sentences that are correct for academic or legal writing. Pair it with a readability analyzer when the score matters, and read how to improve a reading ease score before cutting sentences to chase a number.
5. Google Docs and Microsoft Word
Both editors have counted words for years, and for long documents they stay the most convenient option because the count is already there. Docs shows a live count under the Tools menu and can pin it to the screen; Word puts words, pages, characters, paragraphs and lines in a clickable status bar.
Neither handles characters well for social or SEO work. Word can produce a character count, but the dialog is buried and neither tool knows anything about platform limits. Both are also tied to accounts and, for Docs, to cloud storage, which is more commitment than a task this simple requires.
6. Grammarly
Grammarly counts words and characters inside its editor, but you use it for the suggestions. Paste a draft and it returns a correctness score plus flags for grammar, spelling, tone and clarity.
The free tier is useful and the counter is accurate. The catches are that you need an account, the editor is heavier than a plain counter, and you will field suggestions when all you wanted was a number. If a grammar pass is the real job, our grammar checker does the same thing in the browser with no upload; if you only need a count, open a counter.
How to choose
Start with the unit your constraint uses. If the limit is characters, pick something with a target field, meaning Character Count Online or the Glint counter with its limit warnings. If the limit is words, any of them will do and you can choose on extras.
Then ask what else you need from the same paste. Keyword frequency points to WordCounter.net. Sentence-level clarity points to Hemingway or a free readability checker. Grammar points to a checker rather than a counter. If you need two of those, use two tools; they are free, and switching tabs beats compromising on one.
Finally, decide whether the text is sensitive. Client copy, unpublished work and anything under contract should go through a browser-based tool that does not upload. That one filter removes most of the field.
A quick scenario
A writer has 90 minutes to deliver a 1,200-word post with a meta title and description. She drafts in Google Docs, watches the built-in count, and finishes at 1,410 words.
She cuts in three passes: a redundant example section (-160 words), an introduction trimmed to two sentences (-35), and a closing paragraph that restated the opening (-40). That lands at 1,175, inside a sensible range for a 1,200 target.
For the title she drafts four options, checks each against the 60-character budget and keeps the two that fit. The description takes three attempts to reach 154 characters. Counting time: about six minutes. Without a limit-aware counter, that step usually means publishing, seeing the truncation in search results, and editing twice.
Had the draft landed at 900 words instead, the process runs in reverse: check structure with an AI text summarizer to see whether the argument survives compression, then add depth rather than padding. Students working to an essay cap should read the AI essay writer guide, which covers the same discipline for graded work.
Common mistakes
- Counting only at the end, then hacking the text to fit. Count as you draft.
- Confusing characters with spaces and characters without. Nearly every platform limit is with spaces.
- Treating word count as quality. A 2,000-word post of filler loses to 900 dense words.
- Assuming every counter splits words identically. Hyphenated words and contractions vary, so test once.
- Counting Markdown source instead of rendered output. Headers, asterisks and links add characters that never appear on the page, so convert with the Markdown to HTML converter first.
- Ignoring reading time. A 4,000-word article is a 16 to 20 minute commitment at the usual 200 to 250 words per minute.
- Trusting remembered limits. Social character budgets have changed more than once, so verify before you rely on one.
Frequently asked questions
Which free word counter is the most accurate? For plain English prose the major counters agree within a word or two, so accuracy is rarely the real difference; choose on extras such as character limits, reading time or keyword density.
Do word counters count hyphenated words as one word or two? Most treat a hyphenated word as one, but a few split it and behaviour with contractions varies, so run a short test phrase through your tool before trusting a strict limit.
How is reading time calculated? Most tools divide your word count by an assumed 200 to 250 words per minute, which suits general web reading; technical or academic text usually reads slower.
Does Google require a minimum word count to rank? No, Google has no word count requirement, but longer pages often cover a topic more completely, so treat length as a signal of depth rather than a target to hit.
Can I check meta title and description lengths for free? Yes, any counter showing characters with spaces works, and a target field is easier since you can watch the remaining allowance as you write toward 60 and 155 characters.
