A right-click on panel doesn't bring this up and not listed in View/Toolbars or View/Panels ... have a very specific page size so really need to change from default A4.

  • you need make right-click on page and select page properties – Fran Raga May 16 '19 at 18:01
  • I have right-clicked and there is no option for a Composition panel, only Atlas; Guides; Item Properties; Items; Layout; UnDo History, but no Composition. – ClearMappingCo May 16 '19 at 18:24
  • Under Layout/Variables the page size is listed but I can't change it there either. – ClearMappingCo May 16 '19 at 18:32
  • Try right-clicking in the layout, not on the panel. – JoshC May 16 '19 at 18:33
  • Also, could you clarify what version you're running, or include a screenshot what what you do/don't see? – JoshC May 16 '19 at 18:34
