<title>UK TeX FAQ -- question label findwidth</title>
</head><body>
<h3>Finding the width of a letter, word, or phrase</h3>
<p>Put the word in a box, and measure the width of the box. For example,
<blockquote>
<pre>
\newdimen\stringwidth
\setbox0=\hbox{hi}
\stringwidth=\wd0
</pre>
</blockquote><p>
Note that if the quantity in the <code>\</code><code>hbox</code> is a phrase, the actual
measurement only approximates the width that the phrase will occupy in
running text, since the inter-word glue can be adjusted in paragraph
mode.
<p>The same sort of thing is expressed in LaTeX by:
<blockquote>
<pre>
\newlength{\gnat}
\settowidth{\gnat}{\textbf{small}}
</pre>
</blockquote><p>
This sets the value of the length command <code>\gnat</code> to the width of “small”
in bold-face text.
