Hello Matt,
We can change the width by CSS.
It is possible to add CSS code using SharePoint Designer or Content Editor Web Part.
Here is a link that shows how to add CSS to a page

This is a CSS code for your reference that sets width to 700px for elements have .ms-formbody class:
<style type="text/css"> .ms-formbody{ width:700px; } </style>
Thank you
