Centering ornaments from `pgfornaments` around a theorem environment?

Here is my minimal code:

usepackage{lmodern}

usepackage[T1]{fontenc}

usepackage{amsmath}

usepackage{amsthm}

usepackage{pgfornament}



newtheorem{thm}{Theorem}

 end{theorem}



end{document}

It produces the following as output:

enter image description here

The black portions mark the width of the page. See how the ornaments are shifted to the right, rather than actually being "centered" on the page width? How can I fix this?

You should add option [width=13cm] to your used command pgfornament like

pgfornament[width=13cm]{88}

Without this width the ornament is to long to fit into the textwidth of your text.

You can use

usepackage{showframe}

to visualize the typing area and margins.

Your ornaments are actually stretching beyond the margins, as the overfull vbox warnings your code issues, tell you.

enter image description here

So, you could set things up better with a makebox also taking care of indent with:

newcommand*{centeredornament}{noindentmakebox[textwidth][c]{pgfornament[width=1.1textwidth]{88}}}

The [width=1.1textwidth] for the ornament is there to deliberately have it a little larger than textwidth (but centered), as it seems to be your intent. But you can set this value as you please, of course.

Your ornaments are actually stretching beyond the margins, as the overfull vbox warnings your code issues, tell you.

enter image description here

So, you could set things up better with a makebox also taking care of indent with:

newcommand*{centeredornament}{noindentmakebox[textwidth][c]{pgfornament[width=1.1textwidth]{88}}}

In full:

documentclass[12pt,letterpaper]{article}



usepackage{lmodern}

usepackage[T1]{fontenc}

usepackage{amsmath}

usepackage{amsthm}

usepackage{pgfornament}

usepackage{showframe}



newtheorem{thm}{Theorem}



newcommand*{centeredornament}{noindentmakebox[textwidth][c]{pgfornament[width=1.1textwidth]{88}}}



newenvironment{theorem}[1]{centeredornamentbegin{thm}[#1]upshape}{end{thm}vspace{-1ex}centeredornament}



begin{document}
