Pizza Box Sizes, Cake Boxes and Bakery Boxes: A Buyer's Guide

Standard pizza boxes come in 7, 9, 10, 12, 14 and 16 inches, which is about 180 × 180 mm up to 406 × 406 mm, usually 45 to 50 mm deep. Most are made of E-flute corrugated board in brown kraft or white. Cake, pastry and baklava boxes are a different product: folding boxboard, often with a window, handle or insert, built around the product they carry.

This guide gives the size chart for pizza boxes, explains flute and board in plain terms, covers cake, bakery and baklava boxes, and lists what to check before you order printed boxes.

What Are the Standard Pizza Box Sizes?

A pizza box is named after the pizza, not the box. The inside of the box is the pizza’s diameter plus a little clearance, so the crust does not press against the walls. The table shows the standard range.

How to use it:

• Measure the baked pizza, not the dough ball. A pizza spreads in the oven. Measure five finished pizzas and take the largest.
• Depth follows the topping. 45 mm suits a thin Neapolitan or Turkish-style pide pizza; 50 mm or more suits thick crust and heavy toppings, so the lid does not touch the cheese.
• Keep the range short. Three sizes, for example 10, 12 and 16 inches, cover most menus and keep stock and print plates simple.
• Calzone, pide and lahmacun do not need round-pizza boxes: rectangular boxes or flat sleeves fit them better and use less board.

What Is the Difference Between E-Flute and B-Flute?

Corrugated board is three layers: an outer liner, a wavy middle layer called the fluting, and an inner liner. The size of the waves is the flute type. It decides how thick, strong and printable the board is.

Thickness values are typical industry figures; the exact value depends on the board mill.

For most pizzerias, E-flute is the right choice: it is light, folds cleanly, keeps the pizza warm for normal delivery times and gives a good surface for your logo. Move to B-flute if your pizzas are heavier than usual, if boxes stand in tall stacks for a long time, or if you print only a simple one-color logo and want maximum stiffness.

What do board grades like “80 / 112 / 100” mean?

Suppliers describe the board as the weight of each layer in grams per square meter. A brown pizza box might be 80 g testliner outside, 112 g fluting and 100 g kraftliner inside; a white box might use 110 g white-top liner on both sides. Heavier liners make the box stiffer and more resistant to moisture from the pizza. When you compare quotes, compare these numbers and the flute type. The color alone tells you nothing about strength.

Kraft or white?

• Kraft (brown) looks natural, hides grease marks and suits one- or two-color logos.
• White shows colors truer and suits full-color designs and photos.

Both can be printed. The choice is about how the brand should look.

How Do Cake, Pastry and Baklava Boxes Differ?

Bakery boxes carry products that are fragile, sticky or sold by weight, and they are often gifts. They are usually made of folding boxboard (a single, stiff board) rather than corrugated board, because it is smoother, prints better and folds into neat shapes.

What are the standard cake box sizes?

Cake boxes are sized by the cake’s diameter: the base is about 5 cm (2”) wider than the cake, so it can be lifted out without touching the sides, and the height leaves room for cream and decoration.

What are the standard pastry, cupcake and baklava box sizes?

These are typical market sizes, not fixed standards: cake heights, cupcake diameters and baklava cuts differ from shop to shop. Measure your largest product and confirm the inside size of the box before you print.

Three details matter most:

• Window. A window sells the product from the counter. It is a film glued behind a cut-out. Agree the film material with the supplier, since it affects how the box is sorted after use.
• Barrier. Baklava, syrupy desserts and butter pastry need a barrier inside the box so oil and syrup do not soak through. Ask for the barrier type in writing (water-based, PE or PLA) and the food-contact declaration of the finished box.
• Size by product, not by catalog. Bakery products vary more than pizzas. Send the supplier the outer size and weight of your largest product and let them propose the box.

What Should You Check Before Ordering Printed Boxes?

1. Size chart from your own products. Measured pizzas or cakes, with the deepest topping or tallest decoration.
2. Board specification in writing. Flute type, liner and fluting grades, kraft or white.
3. Barrier and food contact. Whether there is a barrier, what it is made of, and a declaration of compliance for the finished box under Regulation (EC) No 1935/2004.
4. Print method and colors. Flexo for simple one- to two-color logos on corrugated board, offset or full color for photographic designs on bakery boxes.
5. Sample before production. Fold the box, fill it, close it, stack it and carry it. A box that cracks at the corner or opens in the bag fails in the street, not in the office.
6. Claims on the print. Since 27 September 2026, Directive (EU) 2024/825 limits generic environmental claims such as “eco-friendly” on products sold to consumers in the EU. Print only claims you can document.
7. Packing and delivery. How boxes are packed (flat, in shrink-wrapped bundles), the carton or pallet quantity and the delivery terms.

Pizza boxes stained with grease are a known problem for paper recycling, and the rules on what goes into the paper bin differ between countries and municipalities. If you sell into the EU, the PPWR (Regulation (EU) 2025/40) will add recyclability requirements for all packaging in the coming years; keep the design simple, with no unnecessary plastic parts, so the box stays easy to recycle.
