Wizards of LaTeX, hear my pray! How can I format equations so their length becomes proportional to textwidth?

Why would you want to do that? That would render them rather ugly and
difficult to read, most of the time.

Well, I would do it because I want to change the paper size of the document and that seems to affect only the text, not the lenght of equations.

Maybe it would be easier to understand your problem if you gave a
minimal example -- two short LaTeX file with te same text before and
after the same equation, but two different page sizes defined in the
preambles.

O.K. here it is:
\documentclass[12pt,a4paper]{article}

\begin{document}
Lorem ipsum dolor sit amet,
consectetur adipiscing elit,
sed do eiusmod tempor incididunt ut labore et dolore magna aliqua:
\begin{equation}
a = b = c = d = e = f = g = h = i = j = k = l = m = n = o = p = q
\end{equation}
\end{document
Thie equation fits the margins of the text, but
\documentclass[12pt,a5paper]{article}
\usepackage[pass]{geometry}
\begin{document}
Lorem ipsum dolor sit amet,
consectetur adipiscing elit,
sed do eiusmod tempor incididunt ut labore et dolore magna aliqua:
\begin{equation}
a = b = c = d = e = f = g = h = i = j = k = l = m = n = o = p = q
\end{equation}
\end{document}
doesn't.
My ignorance smashes me, but still hope for knowledge...

Yes of course. With text TeX can freely break lines whereever needed. An
equation is usually shorter than the avalilable line space. If not, it
is quite difficult to break equations in a sensible way and you
certainly want to do it manually. There is no way to do this
automatically and sensibly TeX does not even try.

Have you tried the `breqn' package? It's not perfect, but appears
to do what you're asking for:

----------------------
\documentclass[12pt,a5paper]{article}
\usepackage[pass]{geometry}
\usepackage{breqn}
\begin{document}
Lorem ipsum dolor sit amet,
consectetur adipiscing elit,
sed do eiusmod tempor incididunt ut labore et dolore magna aliqua:
\begin{dmath}[compact]
a = b = c = d = e = f = g = h = i = j = k = l = m = n = o = p = q
\end{dmath}
\end{document}
----------------------
