Pizza boxes are available in various sizes and structural styles to fit different pizza sizes, from personal servings to extra-large pies. Primarily, the box size depends on the pizza's diameter. However, other factors can influence the required box height and construction, including:
-
Pizza thickness
-
Crust style and thickness
-
Topping quantity and height
-
Required ventilation
-
Stacking and delivery requirements
A box that is too small would be restrictive to the pizza, whereas a box that is too large would result in empty space inside the box. Box size is typically measured in length x width x height, while the pizza size is measured using diameter.
This guide explains common pizza box sizes, dimensions, heights, materials, shapes, and selection factors.
Pizza Box Dimension Chart
| Pizza Diameter | Common Box Dimensions | Approx. Box Dimensions in cm |
|---|---|---|
| 6-8 in | 7 × 7 × 2 or 8 × 8 × 2 in | 17.78 × 17.78 × 5.08 or 20.32 × 20.32 × 5.08 cm |
| 8-10 in | 10 × 10 × 2 in | 25.4 × 25.4 × 5.08 cm |
| 10-12 in | 12 × 12 × 2 in | 30.48 × 30.48 × 5.08 cm |
| 12-14 in | 14 × 14 × 2 in | 35.56 × 35.56 × 5.08 cm |
| 14-16 in | 16 × 16 × 2 in | 40.64 × 40.64 × 5.08 cm |
| 16-18 in | 18 × 18 × 2 in | 45.72 × 45.72 × 5.08 cm |
| 18-20 in | 20 × 20 × 2 in | 50.8 × 50.8 × 5.08 cm |
| 20+ in | 24 × 24 × 2 in. or custom | 60.96 × 60.96 × 5.08 cm or custom |
These are common reference sizes rather than universal standards. Actual box selection should be based on the pizza's diameter and the box's usable internal dimensions.
How are Pizza Box Dimensions Measured?
Measuring the pizza and the pizza box are two different things. To measure the pizza, you have to measure the diameter of the pizza, while to measure the pizza box, you need to measure its length, width, and height.
Measuring the Pizza
To measure a round pizza, you simply have to place a ruler across the center of the pizza from one edge to the other edge. The distance between two edges is the pizza's diameter.
Pizza diameter = the distance across the pizza through its center
Measuring the Pizza Box
To determine the inside of the box, you have to measure its usable length, width, and height. Box dimensions are normally written as
Box dimensions = Length × Width × Height

For example:
Pizza: 16 inches (40.64 cm) in diameter
Box: 16 × 16 × 2 inches (40.64 × 40.64 × 5.08 cm)
Note: Before ordering custom pizza boxes, firstly, brands and restaurants need to check the internal dimensions instead of relying only on the nominal box size. Keep in mind that the internal space needs to accommodate the pizza without unnecessary pressure on the crust, toppings, or lid.
Measuring a Pizza Slice
If you are selling pizza slices, pizza slice boxes are the best choice, but their measurements are different from other box styles. Measuring the slice from the crust to the tip, then measuring its widest point and height, determines the appropriate box size for an individual slice.
You need to measure the length from the crust to the tip of the slice. Also, you need to measure the width and height of the slice. For some pizzas, you will need special packaging. You need to make sure that the packaging matches your product.
Personal Pizza Box Dimensions
Personal sized pizzas normally have a diameter of 6 to 8 inches. In centimeters, this translates into a diameter of 15.24 to 20.32 cm. Personal pizzas are meant to be consumed by a single person; hence, they can do well with small portions.
For pizzas that have a diameter of 6 to 8 inches, 7 x 7 x 2 or 8 x 8 x 2 inches are suitable dimensions, based on the box construction and available space.
| Pizza Size | Box Dimensions (Inches) | Box Dimensions (Centimeters) | Best For |
|---|---|---|---|
| 6" - 8" (15.24 to 20.32 cm) | 8" × 8" × 2" | 20.32 × 20.32 × 5.08 cm | Personal pan pizzas, mini-sized pizzas, or individual slices |
Personal pizza boxes are used for small specialty pizzas too. Always remember to measure the pizza first.
Small Size Pizza Box Dimensions
Small size pizzas have diameters ranging from 8 to 10 inches. This means that their diameters range from 20.32 to 25.4 cm. To package this size of pizza, brands have to choose a 10" x 10" x 2" or 12" x 12" x 2" square pizza box. These box dimensions ensure that there is enough room for the pizza while keeping the box size relatively small.
| Pizza Size | Box Dimensions (Inches) | Box Dimensions (Centimeters) | Best For |
|---|---|---|---|
| 8" - 10" (20.32 - 25.4 cm) | 10" x 10" x 2" (or 12" × 12" × 2") | 25.4 × 25.4 × 5.08 cm (or 30.48 × 30.48 × 5.08 cm) | Small pizzas with fewer toppings |
There are differences among food brands in what to call a particular pizza size. While one brand calls it small, another can refer to it using some other term.
Medium Size Pizza Box Dimensions
Medium-sized pizzas range from 12 to 14 inches (30.48 - 35.56 cm) in diameter, depending on the restaurant and supplier. A 12 × 12 or 14 × 14 inch box can be used depending on the pizza diameter and packaging requirements.
| Pizza Size | Box Dimensions (Inches) | Box Dimensions (Centimeters) | Best For |
|---|---|---|---|
| 12" (30.48 cm) | 12" × 12" × 2" | 30.48 × 30.48 × 5.08 cm | Medium-sized pizzas for sharing |
| 14" (35.56 cm) | 14" × 14" × 2" | 35.56 × 35.56 × 5.08 cm | Large pizzas for family or group sharing |
Large Size Pizza Box Dimensions
Boxes for large pizzas must be spacious enough to fit the crust and toppings. It is necessary that such boxes can be easily closed because it is important to prevent any pressure on the pizza.
When choosing large pizza boxes, you should pay attention to the internal dimensions of the boxes, but not to the names provided by suppliers.
| Pizza Size | Box Dimensions (Inches) | Box Dimensions (Centimeters) | Best For |
|---|---|---|---|
| 14" - 16" (35.56 - 40.64 cm) | 16" x 16" x 2" | 40.64 x 40.64 x 5.08 cm | Large-sized pizzas for sharing |
| 16" - 18" (40.64 - 45.72 cm) | 18" x 18" x 2" | 45.72 x 45.72 x 5.08 cm | Extra-large pizzas for parties and gatherings |
Extra Large and Family Size Pizza Box Dimensions
Extra large pizzas and family-sized pizzas need larger boxes than other sizes. It is very important that there should be enough space left in the box. This ensures that there will be no contact between the pizza’s crust and toppings and the box walls.
For extra-large pizzas, it is necessary that the dimensions of the inner side of the box be checked.
| Pizza Size | Box Dimensions (Inches) | Box Dimensions (Centimeters) | Best For |
|---|---|---|---|
| 18" (45.72 cm) | 18” x 18” x 2” | 45.72 x 45.72 x 5.08 cm | Family-sized pizzas or sharing among a group |
| 20" (50.8 cm) | 20” x 20” x 2” | 50.8 x 50.8 x 5.08 cm | Extra-large pizzas for parties and gatherings |
The packaging for oversized pizzas must be durable enough to safely contain the pizzas during packaging, stacking, and delivery. Customized sizing can prove helpful in some situations.
Materials Used in Pizza Boxes
The choice of material for pizza box construction is usually made using corrugated paperboard due to its lightweight and sufficient rigidity for transport and delivery of pizza products. The external layer can be either kraft brown or white in color according to customers' preferences and needs for printing.
-
Corrugated Paperboard: Main material used for pizza box construction.
-
Kraft-Lined Corrugated Board: Natural brown appearance that works well for plain or branded packaging.
-
White-Lined Corrugated Board: Provides a lighter printable surface suited to logos, graphics, and detailed branding.
The type and quality of the material depend on the size of the pizza.
Pizza Box Shapes
Pizza boxes are available in different shapes to suit the pizza type, serving format, and packaging requirements.

-
Square pizza boxes: Square boxes are easy to manufacture, stack, store, and transport round-shaped pizzas. They also provide practical space around a round pizza.
-
Round pizza boxes: Round boxes can provide a more specialized presentation and follow the pizza shape. But they require a different manufacturing process than standard square boxes.
-
Slice pizza boxes: For packaging individual pizza slices, triangular boxes are designed to be smaller than whole pizza boxes. They are best for takeout orders, food counters, and single-serving sales.
How to Choose the Right Pizza Box Size
The process involves considering the size of the pizza first, after which the comparison is done with the size of the box.
Below are some of the things that are considered:

-
Pizza diameter: Measure the pizza across its center.
-
Internal box dimensions: Confirm that the usable length and width accommodate the pizza.
-
Box height: Choose sufficient depth for thick crusts and generous toppings.
-
Crust style: Deep-dish and thicker crusts may require additional height.
-
Toppings: Tall or heavily loaded pizzas may need more clearance.
-
Board construction: Larger or heavier pizzas may require a stronger corrugated construction.
-
Delivery and stacking: Consider how boxes will be handled, stacked, and transported.
-
Slice packaging: Use a dedicated slice box for individual portions.
-
Custom sizing: Choose a custom box when the pizza does not fit common dimensions.
In terms of packaging choices, one can consider pizza boxes. Other packaging options include customized pizza boxes.
Are Pizza Boxes Recyclable?
Yes, they are recyclable, as they are empty and free of major food waste according to local recycling programs. The EPA says pizza boxes can be recycled even if they contain some grease.
Firstly, you have to remove food scraps, then flatten the box into a sheet, and check your local recycling guidelines. Tear off heavily soaked or cheesy bottoms and throw them away for decomposition. But keep in mind that materials and preparation requirements can vary by community.
