Tri-fold brochures are made out from a sheet of paper that is folded two times. Looking at the brochure inside, you fold the right panel inwards first, and then you fold the left panel, inwards as well, so that it sits on top of the right panel. Tri-folds have 6 panels to place information on – 3 “outside” panels and 3 “inside” panels. The 6 panels are almost* the same size. Overall, tri-fold brochures are versatile and great for most marketing campaigns.
