The list of methods to do FontMetrics are organized into topic(s).

Method

intgetMaxFontHeight(final java.awt.Font font)
Gets the maximum font height used by of ALL characters, as recorded by the font. 
BufferedImage image = new BufferedImage(1, 1, BufferedImage.TYPE_INT_ARGB);
Graphics2D g = image.createGraphics();
FontMetrics metrics = g.getFontMetrics(font);
int height = metrics.getMaxAscent() + metrics.getMaxDescent();
g.dispose();
return height;
ListgetMonospacedFontNames()
get Monospaced Font Names 
List<String> monospaceFontFamilyNames = new ArrayList<String>();
GraphicsEnvironment graphicsEnvironment = GraphicsEnvironment.getLocalGraphicsEnvironment();
String[] fontFamilyNames = graphicsEnvironment.getAvailableFontFamilyNames();
BufferedImage bufferedImage = new BufferedImage(1, 1, BufferedImage.TYPE_INT_ARGB);
Graphics graphics = bufferedImage.createGraphics();
for (String fontFamilyName : fontFamilyNames) {
    boolean isMonospaced = true;
    int fontStyle = Font.PLAIN;
...
String[][]getMonospacedFontsFamillyName()
get Monospaced Fonts Familly Name 
String[] fontFamilly = GraphicsEnvironment.getLocalGraphicsEnvironment().getAvailableFontFamilyNames();
List<String> mono = new ArrayList();
List<String> notMono = new ArrayList();
for (int i = 0; i < fontFamilly.length; i++) {
    if (isMonospaced(fontFamilly[i])) {
        mono.add(fontFamilly[i]);
    } else {
        notMono.add(fontFamilly[i]);
...
DimensiongetPrefSize(FontMetrics fm, String keyTip)
get Pref Size 
int prefWidth = fm.stringWidth(keyTip) + 2 * INSETS + 1;
int prefHeight = fm.getHeight() + INSETS - 1;
return new Dimension(prefWidth, prefHeight);
StringgetStringForMaxWidth(FontMetrics fm, String s, int maxWidth)
Returns a string that fit into the maximum width based on the parameter string. 
boolean changed = false;
for (int nameWidth = fm.stringWidth(s); nameWidth > maxWidth; nameWidth = fm.stringWidth(s.concat("..."))) {
    s = s.substring(0, s.length() - 1);
    changed = true;
if (changed) {
    return s.concat("...");
return s;
BufferedImagegetStringImage(Font font, String... strs)
get String Image 
BufferedImage image = new BufferedImage(1, 1, 6);
Graphics graphics = image.getGraphics();
graphics.setFont(font);
FontRenderContext fontRenderContext = graphics.getFontMetrics().getFontRenderContext();
Rectangle2D rectangle2D = font.getStringBounds(getStringArrayMaxLengthString(strs), fontRenderContext);
graphics.dispose();
int width = (int) Math.ceil(rectangle2D.getWidth());

...
intgetStringLengthInPixels(String s, Graphics g)
get String Length In Pixels 
return Toolkit.getDefaultToolkit().getFontMetrics(g.getFont()).stringWidth(s);
RectanglegetStringRect(Font f, String s)
get String Rect 
Graphics g = image.createGraphics();
Rectangle r = g.getFontMetrics(f).getStringBounds(s, g).getBounds();
g.dispose();
return r;
PointgetTextCenterShear(final FontMetrics fm, final String text)
Returns shear to center text 
return new Point(getTextCenterShearX(fm, text), getTextCenterShearY(fm));
intgetTextCenterShearX(final FontMetrics fm, final String text)
get Text Center Shear X 
return -fm.stringWidth(text) / 2;
