If the target demographic you’re designing for is female, there’s something you should know: make it round.
No joke. Molly has a great article and some insight into what attracts male and female users to particular designs. Men prefer straight and more angular things while women often opt for designs characterized by the use of circles. Here’s an excerpt.
Molly: “That women like circles and men prefer straight lines is no accident. If we look to known archetypes, the circle signifies the feminine and attributes considered to be feminine: curves, community and cooperative communication. The straight line signifies the male not only physically, but in terms of representing focus and linear thought and communication.”
Be sure to read the rest of Molly’s commentary. Very interesting.
