In choosing the size and format of the leaflet printing, bear in mind the budget that you have and the amount of content that needs to be inputted. The fold of the leaflet also varies so you must be keen in choosing. Leaflets may either be in a) "letter fold" - this is an A4 sheet folded down to DL size (210x297mm folded to 210x99mm) and is very common; or b) "single fold" - this is an A4 sheet folded down to A5 size (210x297mm folded to 210x148mm. If you have a lot to say, choose the former.
