# How do I make my closing remarks in a letter one line in LaTex?

My closing remarks appear on two lines.

\documentclass{letter}

\setlength{\voffset}{-0.5in}

\usepackage{indentfirst}
\usepackage[USenglish]{babel}
\usepackage[acronym]{glossaries}
\usepackage{amsmath}
\usepackage{hyperref}
\hypersetup{
allcolors=black,
}

\begin{document}
\begin{letter}{Singapore Botanic Gardens\\ 1 Cluny Road\\ Singapore 259569}
\opening{Dear Dr.~Nura Abdul Karim and Ms.~Serena Lee,}
\vspace{0.25cm}

I am looking forward to this unique opportunity. Please feel free to reach out to me with questions or concerns.

\vspace{0.25cm}
\closing{Thank you for your time and consideration,}

\vspace{0.25cm}
\encl{Curriculum vitae}

\end{letter}
\end{document}

• Welcome to TeX.SX! Please make your code compilable (if possible), or at least complete it with \documentclass{...}, the required \usepackage's, \begin{document}, and \end{document}. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to give you a hand. Help them help you: remove that one hurdle between you and a solution to your problem. – Stefan Pinnow Apr 3 '19 at 13:50

The width of the \closing is set by the length \indentedwidth. You can set this to be the \textwidth:
\setlength{\indentedwidth}{\textwidth}
