The generator draws words at random from a pool of 93 Latin-looking words, using your browser's secure random number source, so no two runs match and a result cannot be reproduced later. It then builds the text in layers:
| Unit | What you get | Length |
|---|
| Words | One run of words with a capital first letter and a final full stop | Exactly the number you ask for |
| Sentences | Sentences of random length, some with a comma inside | 7 to 15 words each |
| Paragraphs | Blocks of sentences separated by a blank line | 4 to 7 sentences, so 28 to 105 words |
A worked example: three paragraphs of about 60 words each give roughly 180 words, though any single run can fall anywhere between 84 and 315. With the opening option ticked, the first paragraph starts with the 19-word line Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. followed by its normal sentences. In Sentences mode that line replaces the first sentence, and in Words mode the first words follow it and are cut off at your count.
Because the words are drawn independently, the same word can appear twice in a row, and nothing after the opening line is grammatical Latin. That is fine for judging layout, and it is also why the text should never be treated as copy.
Keep the opening line when you show a design to a client, because it signals placeholder at a glance. Untick it when you generate several blocks for one page, otherwise each block starts with the same sentence and the repetition shows up in a grid of cards. For a quick wrapping test the Words unit is enough: about 3 words for a button, 8 for a heading and 25 for an excerpt are realistic starting points.
