# How to reduce the render of tikzpicture

How to reduce the size of the brace and to customize its color to red ? I'm just trying to reduce the render of the tikzpicture.

\documentclass[]{scrartcl}
\usepackage{tikz}
\usetikzlibrary{fit,calc,positioning,decorations.pathreplacing,matrix}

\begin{document}

\begin{tikzpicture}[decoration={brace},scale=2]
\node [rotate=90] (A) {A};
\node [fit=(A)] (fit) {};
\draw [decorate,line width=1pt]
([yshift=-5pt]fit.south west) -- ([yshift=5pt]fit.north west);
\end{tikzpicture}

\end{document}

Like this?

\documentclass[]{scrartcl}
\usepackage{tikz}
\usetikzlibrary{fit,calc,positioning,decorations.pathreplacing,matrix}

\begin{document}

\begin{tikzpicture}
\node [rotate=90,inner sep=0pt,text=red] (A) {A};
\draw [red,line cap=round,decoration={brace,amplitude=0.25ex},decorate,line width=1pt]
(A.north west) -- (A.north east);
\end{tikzpicture}

\end{document}


I have reduced the inner sep to 0pt, removed the fit and added the scale option directly to the node as it seems appropriate. I have also set the line cap=round (thanks to Heiko for noting) as it looks better.

Thanks, I've updated my post about the color choosen. How to make it red? (color of all of the render) – dgs May 18 '14 at 1:30
line cap=round? – Heiko Oberdiek May 18 '14 at 1:31
But that way the font is very big. I'm just trying to reduce all of the render. – dgs May 18 '14 at 1:31
And to set the color of all of the render to red. – dgs May 18 '14 at 1:32
@HeikoOberdiek Yes and thank you. It looks better with that option. – Harish Kumar May 18 '14 at 1:38
