What is Lorem Ipsum?
Lorem Ipsum is placeholder text used in the design and typesetting industry to fill layouts before final copy is available. The text begins with the familiar words "Lorem ipsum dolor sit amet, consectetur adipiscing elit" and continues with a block of Latin-looking prose that has been the industry's standard dummy text since the 1500s. Typesetters and printers used it to demonstrate the visual form of a document without the distraction of meaningful content. When you look at a page filled with Lorem Ipsum, your eye evaluates the font, spacing, line height, and overall layout rather than getting pulled into reading the words. That is the entire point -- it separates design evaluation from content evaluation.
The text traces its origin to De Finibus Bonorum et Malorum (On the Ends of Good and Evil), a treatise on ethics written by the Roman statesman and philosopher Marcus Tullius Cicero in 45 BC. Specifically, Lorem Ipsum is a scrambled excerpt from sections 1.10.32 and 1.10.33 of that work. The original Latin discusses the theory of pleasure and pain -- hedonism as a philosophical doctrine. A typesetter sometime in the 1500s took the passage, altered words, added and removed fragments, and produced the nonsensical but Latin-flavored text that has survived for over five centuries. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, traced the text back to Cicero in the 1980s by recognizing the unusual word "consectetur" and searching classical literature databases.
A Lorem Ipsum generator automates what typesetters once did by hand. Instead of copying and pasting a fixed block of placeholder text and trimming it to fit, you specify how much text you need -- a certain number of paragraphs, sentences, or words -- and the generator produces it instantly. The generated text maintains the statistical distribution of Latin letter frequencies and word lengths that make it visually resemble natural prose. This is important for realistic layout testing. A block of repeated "text text text" or "asdf asdf asdf" does not look like real content and gives designers a distorted sense of how the final page will appear.
