Java: g.drawString() width and height in pixels?

Question

I used fontmetrics to determine the length and height of the String drawn to a jpanel but it gave me incorrect measurements.

The String I used was: "Hello World this is fantastic"

For example: a drew a string with the default font; according to the font metrics the dimensions were: height: 24; width: 224.

when I measured it, it was in fact 148 pixels long and 10 pixels in height. (basically by trial and error)

FontMetrics fm = g.getFontMetrics(this.f);
int Ilength = fm.stringWidth("Hello World this is fantastic");
int Iheight = fm.getHeight();
System.out.println("height: " + Iheight + "; width: " + Ilength);

I am wondering if there is a formula or method in java that can provide the actual height and width of the string in pixels. Thanks!

Did you set the font for the graphics before you drew the string? `g.setFont(f)`. — Paul Samsotha, Oct 11 '14 at 06:44
no. right now i havent set the font. im just using the default. — nathannn, Oct 11 '14 at 07:23
ah I changed it to Times New Roman and it seems to be working now. — nathannn, Oct 11 '14 at 07:26
Get the bounds of the `GlyphVector` instead, as shown in [this answer](http://stackoverflow.com/a/6296381/418556).. — Andrew Thompson, Oct 11 '14 at 08:16
Also consider [`TextLayout`](http://stackoverflow.com/search?tab=votes&q=user%3a230513%20textlayout). — trashgod, Oct 11 '14 at 11:39

I also had this problem. Try to use the method getStringBounds(String,Graphics) of your FontMetrics object.

public Rectangle2D bounds = fm.getStringBounds("Hello World this is fantastic", g);
int Ilength = (int)bounds.getWidth();
int Iheight = (int)bounds.getHeight();
