Just as there are some general, fundamental guidelines that are as applicable to presentation software as they are to billboards and annual reports, there are a few typographical principles that relate directly to PowerPoint alone. Good typography doesn't happen by accident - it is a skill that is developed through practice and experimentation. This includes everything from mixing fonts to choosing colors and point sizes to laying elements on a page in certain relation to other objects. 'Typography' is a medium-independent term used to describe how type is presented. (This not to say good presentation is a substitute for weak content after all, content is king.) Because of this, good typography is as important - if not more so - than any visual element in a presenter's PowerPoint file. Words remain the glue that ties information together. As many charts, videos and illustrations a presentation might have, without text these add up to little more than a collection of disjointed elements pasted between slide transitions. PowerPoint is, fundamentally, a tool for communication, and the heart of that communication is written words.
