# \LARGE{\textbf{…}} vs \textbf{\LARGE{…}} [duplicate]

I am currently writing a project report, and have come across a strange thing.

While making the title page, when I insert the title, if I wrote \textbf{\LARGE{Multi-Server Authentication Scheme Using Biometrics}} the output came as this:

But if I change the code to \LARGE{\textbf{Multi-Server Authentication Scheme Using Biometrics}}, the output looks like this:

Although the above solved my problem, I am curious to know why this happens. The rest of the code needed to fully reproduce this is:

\documentclass[12pt,a4paper]{report}
\begin{document}
\begin{center}
{here goes the above codes for the title}
\end{center}
\end{document}

Compare:

\documentclass[12pt,a4paper]{report}
\begin{document}
\begin{center}
{\bfseries\LARGE Multi-Server Authentication Scheme Using Biometrics}

{\bfseries\LARGE Multi-Server Authentication Scheme Using Biometrics\par}
\end{center}
\end{document}


For the linespacing the current font size at the end of a paragraph is important! And, of course, \Large is a switch and has no arguments!

• I tried this code, but it's not compiling. The error says Paragraph ended before \text@command was complete. <to be read again>  – Abhisek Chaudhuri May 11 at 7:46
• @AbhisekChaudhuri: \LARGE \textbf{Multi-Server Authentication Scheme Using Biometrics} or {\bfseries \LARGE Multi-Server Authentication Scheme Using Biometrics \par} will give you the desired output.
