# How to get nodes equal size in tikz?

Everything I see says to use minimum size, but no matter what I do, the nodes with one digit and two digits are different sizes. Here is my code for reference.

    \begin{tikzpicture}[transform shape]
\foreach \x in {1,...,16}{%
\pgfmathparse{(\x-1)*360/16}
\node[draw,circle,inner sep=0.09em,font=\scriptsize] (N-\x) at (\pgfmathresult:1cm) {$\x$};
}
\foreach \x [count=\xi from 1] in {1,...,15}{%
\foreach \y in {\x,...,16}{%
\path (N-\x) edge[ultra thin,-] (N-\y);
}
}
\end{tikzpicture}


You can set minimum width to be something that contains the numbers:

\node[draw,
circle,
inner sep = 0.09em,
font = \scriptsize,
minimum width = 15pt
] (N-\x) at (\pgfmathresult:2cm) {$\x$};


Or, you can calculate the width automatically by using \eqmakebox from the eqparbox package:

\node[draw,
circle,
inner sep = 0.09em,
font = \scriptsize
] (N-\x) at (\pgfmathresult:2cm) {\eqmakebox[circlenode]{$\x$}};


The latter option requires at least two compilations in order to figure out what the maximum width is for all nodes tagged circlenode.
