Hi Glenn,
Thank you for using syncfusion products,
It is possible to “Extend the number of pages to fit the
content”, for this you need to set PdfLayout type as Paginate, this will extend
the pages until your content is fit. I have attached a simple sample regarding
this in the below link, please check it.

For your another query about “Need
to detect when the content doesn’t fit available area”, I have attached a
simple sample, here we can get the bounds of the text after drawn in
the page by using PdfTextElement class. By comparing the bounds of the text with page
bounds we can able to detect whether the content will be fit into it. Can you
please check with this and let me know if these helps.
