When you’re designing a website, a data sheet or anything else that needs text, you can use filler text to give your client an idea of what it will look like. Lorem Ipsum is the traditional dummy text for graphic designers. It’s not only used to generate text to check layout of the website. Sampling fonts and typography is another of Lorem Ipsum’s uses.
Obviously, you can use other nonsense text but this one is the standard which means you can put more thought and energy into your design and let Lorem Ipsum be your extremely non-sensical copywriter. Use a Lorem Ipsum generator to make sure you get enough words, pages or bytes worth of text, such as http://www.lipsum.com/
