Increase the size of the circle in the following list of references

Question

 \documentclass{article}
    \makeatletter
    \def\@biblabel#1{\textcircled{\scriptsize #1}}
    \makeatother
    \begin{document}
    \begin{thebibliography}{99}
\bibitem{Naj} H. Najafi, Some numerical radius inequality for several operators, Linear Algebra Appl. 588 (2020) 489-496.

\bibitem{Naj} H. Najafi, Some numerical radius inequality for several operators, Linear Algebra Appl. 588 (2020) 489-496.

    \end{thebibliography}
    \end{document}

If the list of references exceeds 10, it may not appear aesthetically pleasing. How can I increase the size of the circle?

It looks like this:

Take a look at https://tex.stackexchange.com/questions/7032/good-way-to-make-textcircled-numbers — Kenneth Odle, Aug 06 '23 at 16:51
@KennethOdle I used this \usepackage{tikz} \newcommand*\circled[1]{\tikz[baseline=(char.base)]{ \node[shape=circle,draw,inner sep=2pt] (char) {#1};}} but the same problem happens — Student, Aug 07 '23 at 07:47
Change inner sep to have a bigger padding between number and circle. Use text width=width("00"), align=right to have a circle that fits a two-digit number even if the content is only one-digit. Use the rounded rectangle to achieve something similar to Sam's answer with TikZ. Though, circledsteps is the preferred solution because it's a lighter approach. — Qrrbrbirlbel, Aug 07 '23 at 09:31

You could use the circledsteps package:

\documentclass{article}
\usepackage{circledsteps}
\makeatletter
\def@biblabel#1{{\scriptsize\CircledText{#1}}}
\makeatother
\begin{document}
\begin{thebibliography}{99}
\bibitem{Naj} H. Najafi, Some numerical radius inequality for several operators, Linear Algebra Appl. 588 (2020) 489-496.

Thanks. I'm happy to see you. I sended you some emails but I don't receive your response. — Student, Aug 07 '23 at 13:17
@Student You're welcome! I did not receive any emails. When did you sent them? — samcarter_is_at_topanswers.xyz, Aug 07 '23 at 13:19
@Student Thanks! Finally found it and replied. Very sorry for the technical problems! — samcarter_is_at_topanswers.xyz, Aug 07 '23 at 14:40
