In the figure form, how to adjust the whole size of "text" and "math" format "as a combined figure" at once?

If this is a usual pdf figure, we can do includegraphics[width=4.4in], such as below, the size is tuned by [width=4.4in]

begin{figure}[htbp]

  centering

  includegraphics[width=4.4in]{.pdf}

  caption{}label{}

end{figure}

Can we adjust the whole overall size of the figure (including the "text" and "math" format) at once by the similar function, like "size"?

I hope to have a 3-times-larger figure overall.

usepackage{mathtools,amssymb}

begin{figure}[!h]

begin{center}

begin{gather*}

overbrace{underbrace{A times B}_Etimes

           underbrace{Ctimes {D}}_{EFG}}^{text{ABCDEFG}} \[-normalbaselineskip]

underbrace{kern5em}_{text{family}}

end{gather*}

end{center}

caption{}

end{figure}

end{document}

documentclass[fleqn]{article}

usepackage{mathtools,amssymb,varwidth}

usepackage{showframe}

begin{document}



begin{figure}[!htb]

resizebox{linewidth}{!}{%

  begin{varwidth}{linewidth}

  mathindent=0pt

  begin{gather*}

    overbrace{underbrace{A times B}_Etimes

               underbrace{Ctimes {D}}_{EFG}}^{text{ABCDEFG}}\[-normalbaselineskip]

    underbrace{hphantom{Atimes Btimes Ctimes D}}_{text{family}}

    end{gather*}

  end{varwidth}}

  caption{foo}

end{figure}

end{document}

Instead of resizebox you can also use scalebox:

[...]

begin{figure}[!htb]

centering

scalebox{3}{%

  begin{varwidth}{linewidth}

[...]

If you want to resize content using a specific width/height, then you can use resizebox{<width>}{<height>} (using ! to maintain the aspect ratio if you only specify one or the other). If you want to scale content using a number, you can use scalebox{<num>}:

documentclass{article}



usepackage{graphicx,amsmath}



begin{document}



begin{figure}

  centering

  scalebox{3}{$displaystyle % If needed...

    underbrace{

      overbrace{

        underbrace{

          A times B

        }_E times underbrace{

          C times D

        }_{EFG}

      }^{text{ABCDEFG}}

    }_{text{family}}

  $}

  caption{A caption}

end{figure}



end{document}

I've nested the family underbrace as part of the bigger expression, so there's no need to manually place it based on the location. Also note the use of centering rather than the center environment, and there's no need for using gather.
