With a Word Counter the number of words in a text can be counted. Many of these tools also include the number of characters, number of sentences and number of breaks. The numbers are often calculated and displayed in real time as soon as text is entered in the input field.
Word Counters are handy tools when it comes to maintaining an exact text length. This is useful for example when writing Twitter tweets (maximum 140 characters long) or snippets for Google (maximum 160 characters). But also for authors of scientific papers, online articles or blog postings Word Counters can be essential, because often a minimum length has to be reached.
