The Myth of "Seven, Plus or Minus 2"

In Webreview, James Kalbach talks about the breadth versus depth issue and how George Miller's Magical number 7 should not be applied to web navigation.

    A closer reading shows that Miller makes no conclusions that can be directly applied to web navigation.


    Clearly, the optimal number of menu items cannot be reduced to one generalized rule applicable in all situations. Instead, when planning the information architecture of a site, the two most important considerations are breadth versus depth and the display of information.

This seems to be on a lot of our minds lately. Kalbach suggests that well-conceived display of navigation and striking a balance between breadth and depth are better practices than following any one rule. The article offers some suggestions in practice based on example sites.
