Because you can t count on a particular font being available  a good approach is to derive a new font from the current font   This gives you the same family  weight  etc  just larger     Font currentFont   g getFont    Font newFont   currentFont deriveFont currentFont getSize     1 4F   g setFont newFont     You can also use TextAttribute     Map lt TextAttribute  Object gt  attributes   new HashMap lt  gt      attributes put TextAttribute FAMILY  currentFont getFamily     attributes put TextAttribute WEIGHT  TextAttribute WEIGHT SEMIBOLD   attributes put TextAttribute SIZE   int   currentFont getSize     1 4    myFont   Font getFont attributes    g setFont myFont     The TextAttribute method often gives one even greater flexibility   For example  you can set the weight to semi-bold  as in the example above   One last suggestion    Because the resolution of monitors can be different and continues to increase with technology  avoid adding a specific amount  such as getSize   2 or getSize   4  and consider multiplying instead   This way  your new font is consistently proportional to the  current  font  getSize     1 4   and you won t be editing your code when you get one of those nice 4K monitors
