Five panel folder boxes are great for many purposes. The width of two of the panels are equal to the depth of the box and the width of three panels are equal to the width of the box. The length of the end flaps can be half the width and depth of the box respectively, or they can be equal to the width and depth and therefore overlap each other. If you chose to overlap them, be sure to allow a little extra where you crush-fold so they will be able to overlap easily.
These boxes are made with four crush-folds along the length of the box to define the five panels, and two crush-folds to define the end flaps. One end flap can also be configured so it inserts inside — up against a sidewall.
