Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum
Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source.
Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.
It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English.
Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
On the other hand, we denounce with righteous indignation and dislike men who are so beguiled and demoralized by the charms of pleasure of the moment, so blinded by desire, that they cannot foresee the pain and trouble that are bound to ensue; and equal blame belongs to those who fail in their duty through weakness of will, which is the same as saying through shrinking from toil and pain. These cases are perfectly simple and easy to distinguish. In a free hour, when our power of choice is untrammeled and when nothing prevents our being able to do what we like best, every pleasure is to be welcomed and every pain avoided.
There was that time artists at Sequence opted to hand-Sharpie the lorem ipsum passage on a line of paper bags they designed for Chipotle—the result being a mixture of avant-garde, inside joke, and Sharpie-stained tables. Those with an eye for detail may have caught a tribute to the classic text in an episode of Mad Men (S6E1 around 1:18:55 for anyone that didn't). And here is a lorem ipsum tattoo.
The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham.
One brave soul did take a stab at translating the almost-not-quite-Latin. According to The Guardian, Jaspreet Singh Boparai undertook the challenge with the goal of making the text “precisely as incoherent in English as it is in Latin - and to make it incoherent in the same way”. As a result, “the Greek 'eu' in Latin became the French 'bien' [...] and the '-ing' ending in 'lorem ipsum' seemed best rendered by an '-iendum' in English.”
Second, use lorem ipsum if you think the placeholder text will be too distracting. For specific projects, collaboration between copywriters and designers may be best, however, like Karen McGrane said, draft copy has a way of turning any meeting about layout decisions into a discussion about word choice. So don't be afraid to use lorem ipsum to keep everyone focused.
