I've seen a lot of questions about, separately and together, landscap-ing one page and really wide tables. These I see usually involve packages changepage and/or geometry, and lscape or pdflscape. I've also seen where people ask about centering these things vertically and horizontally.
What I would like to see (not for printing) is to take one page in a amsart class document, rotate it to landscape (I don't care about the header/footer stuff), and put a really wide table on it - so wide the page would have to be say 30 inches wide.
I've managed to put in a single landscaped page with a wide table on it, but cannot seem to change the page dimensions, even with newgeometry.
Attached is the MWE.
Sorry if I overlooked an answer to this question.
\documentclass{amsart} %{standalone}
\usepackage{graphicx}
\usepackage{tabu}
\usepackage{booktabs}
\usepackage{rotating}
\usepackage{tabularx}
\usepackage{multirow}
\usepackage{lipsum}
\usepackage{geometry}
\usepackage{float,pdflscape}
\usepackage{breqn}
\begin{document}
\lipsum[5-14]
which shows errors only up to close to $TSM$.

I also usually use lualatex and bibtex (which I left out)...


\newgeometry. You have to do it in the preamble. Are you sure that you have only a one page document? – Oct 20 '15 at 22:44\geometry{paperwidth=16in,paperheight=30in}in the preamble. And this will be effective for all pages. paper size can't be changed midway. – Oct 20 '15 at 22:47geometry. – cfr Oct 20 '15 at 23:15typeareasolution would be my first choice. – cfr Oct 20 '15 at 23:20typeareaoption. The nice thing about this is that everything else will be automatically reconfigured. If you are using the accepted solution, read through the comments there for Some Caveats and Things You Should Know ;). – cfr Oct 20 '15 at 23:44
