I find the arm length percentage text odd.

How about:

The physical size of the screen in combination with the size of the
reference pixel as defined in [css-values-ref-here] results in a
considerably smaller initial containing block than for which most
sites were designed.

wider -> larger

remove "actual" since it could be confused with the term introduced
later in this spec.

How about:

As a result, many mobile browser vendors use a fixed initial
containing block size that is larger than the viewport. In addition to
scrolling or panning, zooming is often used to change between an
overview of the document and zoom in on particular areas of the
document to read and interact with.

OK.

Drop "things such as"?

Drop "universally"?
