Contador de palavras

Sobre a contagem de palavras

A word counter is a tool that measures the length of a piece of text by counting its words, characters, sentences, and paragraphs. Writers, students, editors, marketers, and translators use word counts every day because so many publishing platforms, academic institutions, and advertising systems set limits or expectations in terms of words or characters rather than pages. This word counter runs entirely in your browser: the text you paste is never uploaded to a server, which makes it safe for confidential drafts, client work, or unpublished research.

Counting words sounds trivial, but different tools can disagree because "word" is not defined identically everywhere. Most counters, including this one, treat any sequence of characters separated by whitespace as one word, so "state-of-the-art" counts as a single word while "state of the art" counts as four. Hyphenation, numbers, URLs, and emoji can all shift the total, so when a limit really matters — an academic abstract, a contest entry, a legal filing — always check which counting rule the recipient applies.

Como este contador de palavras funciona

The tool splits your text on whitespace, discards empty fragments, and reports the number of remaining fragments as the word count. It also reports total characters, characters excluding spaces, the number of sentences (text separated by ".", "!", or "?"), and the number of paragraphs (blocks separated by blank lines). Reading time is estimated at 225 words per minute, a figure in the middle of the commonly cited 200–250 words per minute range for adult silent reading of English prose reported in reading-speed research such as Brysbaert (2019, Journal of Memory and Language), which found an average of about 238 words per minute for non-fiction.

Limites típicos de palavras e caracteres

The table below collects widely published limits for common formats. Platform limits change over time, so treat these as typical values and verify with the platform before submitting final work. College essay lengths come from the Common Application, which sets a 650-word ceiling for its personal essay; the meta description figure reflects Google's guidance that it typically truncates snippets after roughly 155–160 characters.

Contagem de palavras e qualidade de escrita

A word count is a diagnostic, not a goal. A focused paragraph that makes one point well usually beats a padded one that hits a number. That said, length expectations do correlate with content performance in publishing: long-form guides of roughly 1,500–2,500 words are a common target for blog articles because they can cover a topic thoroughly, while product descriptions, captions, and subject lines reward brevity. Use the counter to check that you are inside the constraints that matter for your format, then edit for clarity.

Word counts also anchor professional rates. Freelance writing is commonly quoted per word, and translation is priced per source word in most of the industry, so an accurate count directly affects invoices. Editing and proofreading estimates likewise scale with length, which is why agencies ask for the document before quoting.

For students, assignment briefs usually state limits in words because pages depend on font and spacing choices that vary between submissions. The Common Application caps its personal essay at 650 words, and many university honors theses set word ranges rather than page counts for the same reason. Checking the count before submitting avoids penalties that some institutions apply mechanically.

Reading time estimates have practical uses beyond blog posts: speech writers plan talks at roughly 130–150 spoken words per minute for a measured delivery, a range long used in public-speaking guidance and congressional floor-time estimates. A 10-minute talk therefore needs roughly 1,300–1,500 words of script — considerably slower than silent reading, because speaking forces pronunciation, pauses, and breaths.

Character counts matter most where systems enforce truncation. A single SMS segment holds 160 characters in the GSM-7 encoding; beyond that the message is split or re-encoded. Search snippets, ad headlines, and notification titles all truncate, so front-loading key information within the first characters is standard practice among copywriters.

Perguntas frequentes

Como este contador de palavras define uma palavra?

Qualquer sequência de caracteres separada por espaços em branco conta como uma palavra, então compostos com hífen como "state-of-the-art" contam como uma única palavra e números contam como palavras.

Meu texto é enviado para algum lugar?

Não. Toda a contagem acontece no seu navegador com JavaScript. Nada é enviado a um servidor, armazenado ou registrado.

Como o tempo de leitura é calculado?

O tempo de leitura é estimado em 225 palavras por minuto, dentro da faixa de 200–250 ppm comumente citada para leitura silenciosa de adultos; a pesquisa de Brysbaert (2019) aponta uma média próxima de 238 ppm em não ficção.

Por que outros contadores mostram um total diferente?

As ferramentas diferem em palavras com hífen, emojis, números isolados e se uma URL isolada é uma palavra ou várias. Pequenas diferenças de algumas palavras são normais e raramente importam, a menos que haja um limite rígido.

Caracteres com ou sem espaços importam mais?

Depende da plataforma. Redes sociais e SMS normalmente impõem limites de caracteres incluindo espaços, enquanto alguns fluxos de tradução e publicação cotam contagens por caractere excluindo espaços.
