Nowadays, differences between men and women in computer science have become a concern in the scientific society. But few studies focus on possible gender differences in web design. We have thus tackled the problem and conducted a statistical analysis in the field. We have selected male and female sites and analyzed them according to a list of graphic variables including the number of colours in the site, the type of these, the type of background, the presence of graphics and their types etc. We have also questionned male and female students about their preferences in web design.
