What are the standard sizes for pizza boxes

The corresponding inner dimensions of a square box for a standard round pizza are as follows:

6-inch (15cm) → 18×18cm;
8-inch (20cm) → 23×23cm;
10-inch (25cm) → 28×28cm;
12-inch (30cm) → 33×33cm;
14-inch (35cm) → 38×38cm.

The height is typically 3.5–5.0cm. Larger sizes require additional height to prevent collapse. When customizing, allow a 1–2cm gap for easy handling and consider stacking stability (lid embedding depth ≥10mm). Irregularly shaped pizzas (such as square or heart-shaped) can be custom-made with die-cut boxes, but the mold fee is approximately 2000–5000 RMB, with a minimum order quantity of ≥5000 pieces.
