Why Word and Character Counts Differ
Published
A “word” depends on a counting rule
A word counter needs a rule for separating text. Here, a run of letters or digits forms a word, and an apostrophe or hyphen inside that run stays attached. “Can't” counts as one word, as does “well-known.”
Another application may split those examples. Different totals do not necessarily mean that either count is wrong. For a competition, submission form, or school assignment, follow the recipient's stated counting rules.
With and without whitespace
The character count with spaces includes letters, punctuation, spaces, and line breaks. The second count removes whitespace, including spaces, tabs, and line breaks.
Windows line endings are normalized to one line break. This prevents the same text from receiving a different count merely because it came from another operating system.
One visible symbol can have several components
The counter measures Unicode code points. Some emoji contain multiple code points: skin-tone modifiers, joining characters, and several symbols can combine into one visible image.
An accented letter can also be encoded in more than one way. The reported count may therefore differ from the number of symbols you would count by eye.
Sentences and paragraphs
Sentence endings are estimated from periods, question marks, and exclamation marks. Abbreviations can produce extra counts. This is a practical indicator, not a complete grammar analysis.
Paragraphs are separated by a blank line. A single line break within a block of text remains in the same paragraph. The counters update locally as you type.
