What is counted
Words are runs of characters separated by whitespace, so "well-known" is one word and "e-mail" is one word. Characters are counted as visible symbols, which means an emoji or an accented letter counts once. Sentences end at a period, question mark, exclamation mark or ellipsis; paragraphs are blocks separated by a blank line.
Reading and speaking time
Reading time assumes 238 words per minute, a commonly cited average for silent reading of non-fiction by adults. Speaking time assumes 150 words per minute, a comfortable pace for a presentation or voice-over. Treat both as estimates: technical text reads slower, and everyone speaks at their own speed.
Typical limits to check against
Meta descriptions work best under about 155 characters, X (Twitter) posts allow 280, SMS segments hold 160 and many application forms cap essays by words or characters with spaces. Use the character counts here to check before you submit; different sites may count line breaks differently, so leave a small margin.
Example
Counting a two-sentence text.
