    Can you specify what aspects should be different to \sqrt{x}? – user36296 May 9 '17 at 20:09

    I need the square root to look curly and bold like the one in the picture. I don't know what package I have to use, but inside the square root is also Times (New) Roman font. – Furfurr May 9 '17 at 20:16

    Maybe the answer could be updated. As the 'random guesses' by @samcarter show, no one really has a clear idea what you want. Maybe describe the look that you are rooting for (pun intended), or say what's bad about the standard $sqrt{x}$. – Narusan May 9 '17 at 20:39

    Please explain what you mean by "curly". To be honest, one doesn't come across this adjective very often when discussing the shape of square-root symbols. – Mico May 9 '17 at 20:40

    Has the image that you have posted been produced with (some variant of) TeX, or by some other means? – GuM May 9 '17 at 21:02

I guess you are looking for the services of the newtxmath math font package. Note that if you use it, you should probably also use the companion newtxtext text font package. Do check, though, if you want to (or are allowed to) use a Times Roman clone for your document.

enter image description here

\documentclass{article}
\usepackage{newtxtext,newtxmath}
\begin{document}
$\sqrt{x}$
\end{document}
  • I've already tried newpxmath, but it's still not curly enough. Thanks anyway. – Furfurr May 9 '17 at 20:30
  • @Furfurr - OK, I switched the answer to newtxmath. Any better? Maybe you should explain what you mean by "curly". – Mico May 9 '17 at 20:31

    @GustavoMezzetti - Thanks. I wish I understood better what "curly" is supposed to mean in the context of square root symbols. – Mico May 9 '17 at 20:53

    @GustavoMezzetti - Ah, I just noticed that the OP edited the query. I guess he/she means "curved" or "curvy" rather than "curly". – Mico May 9 '17 at 20:55

    Yes, the bar of the root is rounded at the edge: I guess this means that the radical has not been produced by TeX’s “Rule 11”, which uses a horizontal rule… – GuM May 9 '17 at 20:59

A root sign with round corners:

\documentclass{article}
\usepackage{mathptmx}

\begin{document}

\begin{equation}
\sqrt{x}
\end{equation}

\end{document}

  • I vote this to be the curliest! – beldaz May 10 '17 at 4:49

If you want more vertical distance between the $x$ and the $\sqrt$ sign then try

\documentclass{article}


\begin{document}
    \[
    \sqrt{x\vphantom{^2}}
    \]
\end{document}

  • I don't need more space in the square root, I need the square root to look curly and bold like the one in the picture. I don't know what package I have to use, but inside the square root is also Times (New) Roman font. – Furfurr May 9 '17 at 20:15

I have used, for times, \usepackage[lite]{mtpro2} and \usepackage{letltxmacro}(do you want in this mode?).

enter image description here

\documentclass[border=1pt]{standalone}
\usepackage{letltxmacro}
\usepackage[lite]{mtpro2}
\makeatletter
\let\oldr@@t\r@@t
\def\r@@t#1#2{%
\setbox0=\hbox{$\oldr@@t#1{#2\,}$}\dimen0=\ht0
\advance\dimen0-0.2\ht0
\setbox2=\hbox{\vrule height\ht0 depth -\dimen0}%
{\box0\lower0.4pt\box2}}
\LetLtxMacro{\oldsqrt}{\sqrt}
\renewcommand*{\sqrt}[2][\ ]{\oldsqrt[#1]{#2} }
\makeatother



\begin{document}
$\sqrt{x} \quad \oldsqrt{x}$
\end{document}
  • Do you have a package that makes the square root curly? – Furfurr May 9 '17 at 20:35
  • For my opinion, there are package that makes the square root curly. Sorry. – Sebastiano May 10 '17 at 19:51
