change the fontsize of text and space between columns in a table

I try to make a table to a two columns text but the space between columns and the fontsize in the table is big and extend more than the space I would like to fill. How could I reduce the space between columns a bit and change the fontsize of the text in the table ?

\begin{document}
\begin{table}
\centering
\begin{tabular}{@{}*4c@{}}
  \toprule[1.5pt]
 & BIAS &  $\sigma$& OUT.[$\%$] \\
\hline
Five (17$\leq$ R $<$ 21) &-0.0099$\pm$0.0001&0.0004$\pm$0.05&0.003$\pm$0.0001 \\

Seventeen&0.0008$\pm$0.007&0.07$\pm$0.0004&0.0002$\pm$0.073\\
Five (21$\leq$ R $<$ 23)&-0.053$\pm$0.0015&0.0002$\pm$0.04&1.002$\pm$0.006\\
Seventeen&0.0001$\pm$0.01&0.007$\pm$0.004&0.0011$\pm$0.04\\
\bottomrule[1.5pt]
\end{tabular}
\end{table}
