Are appendices included in the maximum page count for conference papers? I am writing research paper following the ACM 2-column format in Latex. The conference is limiting the number of pages by only 6-8 pages. So far, my paper has a lot of figures and tables and would be impossible to fit them all in 8 pages. 

So what I want to do, is to include an extra page as an Appendix at the end. will it be considered as 8 pages or 9 pages? Will it be considered that I am following the conference regulation?
Are appendices included in the maximum page count for conference publications?


In my experience from CS, typically yes. That is because the page limit has (at least) three purposes:


To ensure everyone gets the same space to make their point (whether that increases fairness or actually decreases it - different topics may require different amounts of space - is a different question).
To limit the amount of information/contributions per publication, lest the conference talk be just an exemplary excerpt that fails to encompass the entirety of the paper.
To actually limit page size in printed proceedings. I base this on the observation that I have come across conferences that would charge authors for extra pages, and even a few that would charge authors or put a (lower-than-total-pages) limit on pages with coloured content.


It is for the latter point that "bonus material" such as appendices also counts towards the maximum paper length.
