The information in your affidavit should only include the evidence on which you intend to rely on to support your application (orders you are seeking). If you are only seeking for example a few Interim orders then your affidavit will be much shorter than if, for instance, you are seeking both Interim and Final orders in your application.
At times judges will make directions specifying maximum length.

this judgement < < < relating to an “extreme-sized” affidavit, of retired former FM/Judge David Halligan (whom I have been told was a straight shooter with a lot of tolerance for litigants in person but zero tolerance for laziness, incompetence, dishonesty and waisting time/resources) would likely sum up the general attitude of many judges to lengthy affidavits.
Note at paragraph 5, Halligan mentions how little of the affidavit will likely be relied on... “
That is a totally unacceptable approach with a document comprising five volumes and 733 pages, less than one sixth of which will ultimately be relied on.”
