Council work is specified rather than designed on the day: a size that fits A4, a print that survives a wet weekend, and a quantity fixed to an event.

Most council bags carry paper: programmes, forms, information packs. That makes A4 the shape to design around, and a 320 x 100 x 420mm bag takes an A4 folder flat with room beside it.
Because these are tied to a date, the deadline matters more than usual. Tell us the event date with the enquiry and we will say plainly whether it is achievable rather than find out later.
