What each statistic means

Characters counts every character including spaces and punctuation. Chars (no spaces) subtracts whitespace, useful for platforms with non-space character limits. Words counts sequences of non-whitespace characters. Sentences counts terminal punctuation marks (.!?). Paragraphs counts non-empty blocks of text separated by blank lines. Reading time is estimated at 200 words per minute, a typical reading speed for adults.
