— title: Automatic sizing of `minipage` category: misc permalink: /FAQ-varwidth —

The `minipage` environment requires you to specify the width of the “page” you're going to create. This is sometimes inconvenient: you would like to occupy less space, if possible, but `minipage` sets a box that is exactly the width you specified.

The [`pbox`](https://ctan.org/pkg/pbox) package defines a `\pbox` whose width is exactly that of the longest enclosed line, subject to a maximum width that you give it. So while `\parbox{2cm}{Hello world!}` produces a box of width exactly `2cm`, `\pbox{2cm}{Hello world!}` produces one whose width is `1.79cm` (if one's using the default `cmr` font for the text, at least). The package also provides a `\settominwidth[min]{length}{text}` (which looks (almost) like the standard `\settowidth` command), and a `\widthofpbox` function analogous to the `\widthof` command for use with the [`calc`](https://ctan.org/pkg/calc) package.

The [`eqparbox`](https://ctan.org/pkg/eqparbox) package extends [`pbox`](https://ctan.org/pkg/pbox)'s idea, by allowing you to set a series of boxes, all with the same (minimised) width. (Note that it doesn't accept a limiting maximum width parameter.) The package documentation shows the following example drawn from a joke _curriculum vitae_: ```latex \noindent% \eqparbox{place}{\textbf{Widgets, Inc.}} \hfill \eqparbox{title}{\textbf{Senior Widget Designer}} \hfill \eqparbox{dates}{\textbf{1/95–present}}

\noindent% \eqparbox{place}{\textbf{Thingamabobs, Ltd.}} \hfill \eqparbox{title}{\textbf{Lead Engineer}} \hfill \eqparbox{dates}{\textbf{9/92–12/94}} ``` The code makes the three items on each of the heading lines have exactly the same width, so that the lines as a whole produce a regular pattern down the page. A command `\eqboxwidth` allows you to use the measured width of a group: the documentation shows how the command may be used to produce sensible-looking columns that mix `c`-, `r`- or `l`-rows, with the equivalent of a `p{…}` entry, by making the fixed-width rows an [`eqparbox`](https://ctan.org/pkg/eqparbox) group, and making the last from a `\parbox` using the width that's been measured for the group.

The [`varwidth`](https://ctan.org/pkg/varwidth) package defines a `varwidth` environment which sets the content of the box to match a “narrower natural width” if it finds one. (You give it the same parameters as you would give `minipage`: in effect, it is a “drop-in” replacement.) [`Varwidth`](https://ctan.org/pkg/Varwidth) provides its own ragged text command: `\narrowragged`, which aims to make narrower lines and to put more text in the last line of the paragraph (thus producing lines with more nearly equal lengths than typically happens with `\raggedright` itself).

The documentation (in the package file) lists various restrictions and things still to be done, but the package is already proving useful for a variety of jobs.
