How to control font sizes in pgf tikz graphics in latex

Question

I m creating graphs in pgf tikz  When I use these in my document they are scaled  several are in minipage subfig like environments  When this happens the font sizes are scaled with the graphics making them very small or unreadable  I ve been through the manual but have so far been unsuccessful in my attempts to control this   Is there a way to set the font size directly  What options are there   One aswer given below shows how to how to use the  tikzstyle font option to specify the font size within the tikzpicture environment   Right now I am using    beginppgfgraphicnamed graph   input graph tex   endpgfgraphicnamed   The tikzpicture environment is used in the input file  Are there anyways to specify font size in the setup I m using  Is this perhaps the issue  The graph tex file is generated automatically via another program   In addition to setting font size for individual graphics it would be ideal to have a parameter to globally set font size for all tikz graphics  I guess the issue is the scaling in minipage or subfig   Many thanks   Jay

begin tikzpicture        tikzstyle every node   font  small    end tikzpicture    will give you font size control on every node

You can also use    usepackage anyfontsize    The huge advantage of the anyfontsize package over scalefnt is that one does not need to enclose the entire  tikzpicture  with a  scalefont environment    Just adding  usepackage anyfontsize  to the preamble is all that is required for the font scaling magic to happen

I found the better control would be using scalefnt package    usepackage scalefnt        scalefont 0 5   begin tikzpicture       end tikzpicture
