I think a better way to do this is to change the base size argument  It will increase the text sizes consistently   g   theme grey base size   22    As seen here

To change the size of  almost  all text elements  in one place  and synchronously  rel   is quite efficient     g theme text   element text size rel 3 5    You might want to tweak the number a bit  to get the optimum result  It sets both the horizontal and vertical axis labels and titles  and other text elements  on the same scale  One exception is faceted grids  titles which must be manually set to the same value  for example if both x and y facets are used in a graph  theme text   element text size rel 3 5              strip text x   element text size rel 3 5              strip text y   element text size rel 3 5

You can change axis text and label size with arguments axis text  and axis title  in function theme    If you need  for example  change only x axis title size  then use axis title x   g theme axis text element text size 12           axis title element text size 14 face  quot bold quot     There is good examples about setting of different theme   parameters in ggplot2 page

If you are creating many graphs  you could be tired of typing for each graph the lines of code controlling for the size of the titles and texts  What I typically do is creating an object  of class  quot theme quot   quot gg quot   that defines the desired theme characteristics  You can do that at the beginning of your code  My Theme   theme    axis title x   element text size   16     axis text x   element text size   14     axis title y   element text size   16    Next  all you will have to do is adding My Theme to your graphs  g   My Theme  if you have another graph  g1  just write  g1   My Theme   and so on
