 From the documentation of ImageSize...

If you like the default size, you can specify ImageSize->Medium in your plots.  
The reason for this behavior is that since, in v6, graphics are now first class 
output objects rather than mere side effects, changing the automatic size based 
upon context can make it easier to work with them.  Imagine, for example, 
outputting a list or a grid of default-sized graphics and trying to get an idea 
for the totality of the output while each graphic is still big enough to compete 
for a standalone-sized portion of the screen.
