I assume that you are using Windows 8.1, like me. Some 8.1 combinations, high DPI monitors, and Swing don't seem to play well together. My fix was to edit the squirrel-sql.bat file and add the following java options right after the existing java option
-Dswing.plaf.metal.controlFont=Tahoma-18 -Dswing.plaf.metal.userFont=Tahoma-18
For reference, the full line is as follows:
start "SQuirreL SQL Client" /B "%LOCAL_JAVA%" -Xmx256m -Dsun.java2d.noddraw=true -Dswing.plaf.metal.controlFont=Tahoma-18 -Dswing.plaf.metal.userFont=Tahoma-18 -cp %SQUIRREL_CP% -splash:"%SQUIRREL_SQL_HOME%/icons/splash.jpg" net.sourceforge.squirrel_sql.client.Main %TMP_PARMS%
EDIT: The above will increase the size for everything except the SQL input field. To do this, go to File-> New Session Properties-> SQL-> SQL Entry Area
