How counting works
A word is any run of non-space characters, so words are counted by splitting the text on whitespace and ignoring empty pieces. Characters are counted two ways — with and without spaces — because publishers and forms differ on which they mean. Sentences are estimated from terminal punctuation (. ! ?) and paragraphs from blank-line breaks.
These counts update instantly as you type, so you can write to an exact limit — a tweet, a meta description, an essay or an abstract — without guessing.

Reading and speaking time
Reading time is estimated at about 200–250 words per minute for silent reading; this tool uses 225. Speaking time, useful for talks and scripts, runs slower — around 130 words per minute. These are averages: dense or technical text reads slower, and a confident presenter may speak faster. The estimates give a reliable ballpark for planning content length, captions or a speech.
