How to Change Font Size in drawString Java
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<TextAttribute, Object> attributes = new HashMap<>();
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.
g.setFont(new Font("TimesRoman", Font.PLAIN, fontSize));
Where fontSize is a int. The API for drawString states that the x and y parameters are coordinates, and have nothing to do with the size of the text.
Font myFont = new Font ("Courier New", 1, 17);
The 17 represents the font size. Once you have that, you can put:
g.setFont (myFont);
g.drawString ("Hello World", 10, 10);
