+/// Measure the layouted size of content.
+///
+/// The `measure` function lets you determine the layouted size of content.
+/// The same content can have a different size depending on the styles that
+/// are active when it is layouted. For example, in the example below
+/// `[#content]` is of course bigger when we increase the font size.
+///
+/// ```example
+/// #let content = [Hello!]
+/// #content
+/// #set text(14pt)
+/// #content
+/// ```
+///
+/// To do a meaningful measurement, you therefore first need to retrieve the
+/// active styles with the [`style`]($func/style) function. You can then pass
+/// them to the `measure` function.
+///
+/// ```example
+/// #let thing(body) = style(styles => {
+///   let size = measure(body, styles)
+///   [Width of "#body" is #size.width]
+/// })
+///
+/// #thing[Hey] \
+/// #thing[Welcome]
+/// ```
+///
+/// The measure function returns a dictionary with the entries `width` and
+/// `height`, both of type [`length`]($type/length).
