Pizza slice box dieline

About this dieline

A pizza slice box is a one-piece triangular box for a single slice of pizza, cake or pie, with a lid hinged on the crust side. Its walls stand up round a triangle and lock into each other with tabs, and the lid closes over them, its two rounded flaps tucked inside the side walls. The slice can be any shape: a wide one from a small pizza or a narrow one from a large pizza or a round cake.

Enter the length from the crust to the tip, the width across the crust, the wall height and the board thickness, and download a print-ready PDF with cut and crease lines. Pizzerias, bakeries and cafés use it for a slice to go; it ships flat and needs no glue.

What size do I need for one slice?

Measure the slice: from the crust to the tip is the length, across the crust is the width, the thickest point with its toppings is the height, each plus 5–10 mm. Slice box templates start at about 240 × 175 × 42 mm for pizza and 130 × 100 × 75 mm for a slice of cake.

Does it need glue?

No. The crust wall locks into the side walls with two tabs, the tip locks with a third, and the lid tucks its flaps inside the side walls. It ships flat and folds by hand.
