Lorem ipsum

Lorem ipsum is dummy text that fills a layout with something that looks like writing but can’t be read. Its even mix of short and long words lets designers judge typefaces, spacing and the overall shape of a page without anyone being distracted by meaning. It turns up in mock-ups, templates and slide decks and, with depressing regularity, on live websites where nobody got round to replacing it.

The words are a mangled passage from Cicero’s De finibus bonorum et malorum (45 BC), a treatise on ethics. “Lorem ipsum” is what remains of “dolorem ipsum”, pain itself, from a sentence observing that nobody pursues pain for its own sake. Typography manuals had used a different passage of Cicero as specimen text since the 18th century, but the version in use today comes from Letraset’s dry-transfer sheets of the 1960s, reportedly supplied by the printing historian James Mosley. Aldus brought it into PageMaker in the 1980s, typed in by hand from one of those sheets, and from there it spread into word processors and content management systems. Even its origin story has been filled in without much care. The claim, repeated across countless websites, that printers have used it since the 1500s began as a guess in a 1994 letter, which its author, the Latin scholar Richard McClintock, has since admitted had no evidence behind it.

Why it matters for content

Real content shapes design. A heading establishes hierarchy, a button enables an action and an error message helps someone recover. Placeholder text reduces all of these to rectangles, encouraging teams to treat content as material poured into a finished container. A design filled with meaningless text can’t show whether its wording helps anyone complete a task. It assumes tidy headings, convenient lengths and content that never needs to explain an error, meet a legal requirement or accommodate a long Welsh place name.

Lorem ipsum also stands for a sequence: design first, words later. Placeholder text does little harm in a process where content and design develop together, and a great deal in one where the words arrive last and must squeeze into whatever space is left. Using representative content early exposes the difficult cases (long names, missing data, translations, warnings, competing priorities) and lets stakeholders judge whether an experience works rather than approving an attractive arrangement of grey bars. When final copy doesn’t exist yet, provisional content clearly labelled as draft is enough to test the proposition and the structure. And lorem ipsum that survives onto a live page is rarely a typo: it’s evidence that nobody was responsible for the words, and readers draw that conclusion quickly.

How AI changes the picture

AI can produce realistic placeholder content in seconds, which is more useful than lorem ipsum when the examples are grounded in the product. It’s particularly good at stress-testing a layout: the longest plausible product name, a heading translated into German, an error message for the worst case rather than the convenient one. Used that way, generated text challenges a design instead of flattering it.

It also removes lorem ipsum’s one safety feature. Nobody mistakes scrambled Latin for finished copy, whereas fluent generated text looks ready to publish. It can be approved in a review as though someone had written it deliberately, set expectations that the real content can’t meet or slip into production without fact-checking or ownership. Draft status and source need to stay visible, whether through labelling, highlighting or a rule that generated placeholders never reach a live environment.

The comparison runs the other way too. Much of what’s now called AI slop does the same job as lorem ipsum, filling space rather than saying anything, except that it can be read. The questions content designers have long asked of placeholder text apply to it directly: what is this for, who is it for and who decided it should be here?
