I am writing my own latex beamer style. I want to use different background graphics depending on the aspect ratio chosen in the documentclass in the main file, like \documentclass[12pt, aspectratio=169]{beamer}

So how can I access the value of aspectratio in my .sty file?

One way could be to use the \ifdimcomp{⟨dimen expression⟩}{⟨relation⟩}{⟨dimen expression⟩}{⟨true⟩}{⟨false⟩} macro to test for different paperwidths (and height in case of 169 and 1610):

\documentclass[
    aspectratio=169
%   aspectratio=43
    ]{beamer}

\begin{document}

\makeatletter
\ifdimcomp{\beamer@paperwidth}{=}{12.80cm}{43}{}
\ifdimcomp{\beamer@paperwidth}{=}{14.85cm}{141}{}
\ifdimcomp{\beamer@paperwidth}{=}{13.50cm}{32}{}
\ifdimcomp{\beamer@paperwidth}{=}{12.50cm}{54}{}
\ifdimcomp{\beamer@paperwidth}{=}{14.00cm}{149}{}
\ifdimcomp{\beamer@paperwidth}{=}{16.00cm}{
    \ifdimcomp{\beamer@paperheight}{=}{10.00cm}{1610}{}
    \ifdimcomp{\beamer@paperheight}{=}{9.00cm}{169}{}
}{}
\makeatother

\end{document}
