Garr Reynolds chooses ten easy to understand rules of design from the 20 presented in the book linked below.
10 design rules to keep in mind
- Communicate — don’t decorate.
- Speak with a visual voice.
- Use two typeface families maximum. OK, maybe three.
- Pick colors on purpose.
- If you can do it with less, then do it.
- Negative space is magical — create it, don’t just fill it up
- Treat the type as image, as though it’s just as important.
- Be universal; remember that it’s not about you.
- Be decisive. Do it on purpose — or don’t do it at all.
- Symmetry is the ultimate evil.
