Anything less than 1.5 miles is walkable in a reasonable amount of time, at least to me - that comes out to about a 30-45 minute "commute." The problem is that everything is so spread out (there's not that much to walk _to_), and walking paths are not guaranteed to all destinations within that distance (walking isn't even safe). I wish American towns and cities were built in the traditional 4-over-1 style of places like Amsterdam, so that even in densely populated areas there was room for shops and restaurants that could survive off of foot traffic. When visiting old European cities not built around automotive infrastructure, it was so easy to get 5+ miles of walking in every day because everything is so close together.
