The most important thing in typography is legibility. To ensure this, we (future) designers follow the rules of typography. The project Wicked Type explores these rules in order to develop more awareness in dealing with them. The following rules were analysed in more detail: the rules for good block and flutter type, how to set hyphenation correctly, what constitutes good spacing, and how to set word spacing correctly. The question arose as to whether good design could be achieved by deliberately breaking these rules. So the topic rules of typography became irregular typography.
