You run pizza shop or thinking to open one. You know the pizza size but do you know the box size. Many owners forget this part. They just grab whatever box they find. But wrong size box means floppy pizza or wasted cardboard. Pizza box size in cm and inches and mm all matter for your business.

In this post I will explain sizes simple. No big words. Just real numbers you can use. We will go over small medium large sizes, conversion between units, and chart to help you pick right one. Lets start.

Why Pizza Box Size in cm Inches and mm All Matter

Different countries use different units. USA uses inches. Europe and Asia use cm and mm. If you order boxes from overseas you must know both. Pizza box size in cm helps you match metric suppliers. Pizza box size in inches works for American made boxes. Pizza box size in mm is useful for precise cutting and printing specs.

When you talk to printer or supplier always confirm which unit they use. Mixing up cm and inches can give you box that is too big or too small. That wastes money and annoys customers.

Small Pizza Box Size for Personal and Kid Pizzas

Small pizza box size is for pizzas around 8 inches or 20 cm. Some shops do 7 inch or 9 inch also. Small box usually measures about 8.5 inches by 8.5 inches or 21.5 cm by 21.5 cm. In mm that is about 215 mm square.

Small boxes are good for personal pizzas, kid meals, or lunch specials. They use less cardboard so cost less. But make sure box is little bigger than pizza so crust does not get squished. Gap of half inch or 1 cm is good.

Medium Pizza Box Size for Family Sharing

Medium pizza box size fits 12 inch pizzas mostly. Some shops call this regular size. What size is a 12 inch pizza box then. Answer is usually 12.5 inches by 12.5 inches or 32 cm by 32 cm. In mm that is about 320 mm square.

Medium box is most popular for takeout and delivery. It fits one big pizza or two small ones side by side if box is bit wider. Many restaurants use medium as their main box. If you need sturdy option for delivery custom corrugated boxes work better than thin paperboard for medium size.

Large Pizza Box Size for Parties and Groups

Large pizza box size is for 14 inch to 16 inch pizzas. Some shops go up to 18 inch for party size. Large box for 14 inch pizza is about 14.5 inches by 14.5 inches or 37 cm by 37 cm. For 16 inch pizza box is about 16.5 inches or 42 cm square. In mm that is 370 mm or 420 mm.

Large boxes need stronger material because pizza is heavy. Thin board bends during delivery. Corrugated is better for large size. Also ventilation holes help steam escape so crust stays crispy.

Extra Large and Square Sizes for Special Pizzas

Some shops make square pizzas or extra large round ones. Square pizza needs square box same size plus half inch gap. Extra large round pizza over 18 inch needs box of 19 inches or 48 cm minimum.

Deep dish pizza needs taller box. Height can be 2 inches or 5 cm instead of normal 1.5 inch or 4 cm. Pan pizza also needs extra height. Always measure your pizza height not just width when ordering boxes.

Also measure pizza height if it is thick style. Add half inch to height for headspace. Box should not press down on toppings. Steam needs room to escape.
