When it comes to good slide management, advice on how many bullets you should have on each PowerPoint slide is all over the place: anywhere from ZERO to 7. Different authorities have 6X6 or 7X7 rules governing the number of bullets, lines or words on a slide. Each to his or her own.
For me, three is the magic number for business presentations. There’re many “Rules of Three” that can be applied to content and performance.
