Size a burger box from your own burgers, not from a supplier's size list: measure the widest point and settled height of burgers built during a real service, add clearance, then group items into as few box sizes as the measurements allow. Skipping this produces two opposite complaints: lids that will not close on the double, and singles sliding around a box built for something bigger. Below are indicative internal dimensions for common builds and the method for setting your own. For materials, print and ordering, see our main page on custom printed burger boxes.
Is there a standard burger box size?
No. Burger boxes are sized to the bun and the build, and every chain's builds differ. Suppliers' "small, medium, large" or 4-inch, 4.5-inch, 5-inch labels are internal naming conventions, not industry standards, so always compare internal dimensions in millimetres.
The bun is the most consistent reference point. Many standard burger buns are around 10-11 cm across, slider buns are smaller, and brioche or gourmet buns often run larger. The box footprint follows the widest point of the assembled burger, which is not always the bun.
Standard burger box sizes in inches and cm
The working ranges below cover most burger builds, in centimetres and inches. Treat them as starting points for your own measurements, not finished specifications. Footprint is the internal base dimension (boxes are usually square or near-square); height is the internal height of the closed box, base plus lid. The same ranges apply whether the buyer asks for burger boxes, Burgerboxen or, in the Netherlands, hamburgerbakjes.
| Format | Typical bun / build | Internal footprint, cm (in) | Closed internal height, cm (in) |
|---|---|---|---|
| Slider / mini | Small bun, single thin patty | 8-10 cm square (3.1-3.9 in) | 5.5-7.5 cm (2.2-3.0 in) |
| Regular single | Standard bun, one patty, light toppings | 10.5-12 cm square (4.1-4.7 in) | 7-8.5 cm (2.8-3.3 in) |
| Chicken burger / fillet | Standard bun, fillet may overhang | 11-12.5 cm square (4.3-4.9 in) | 7.5-9 cm (3.0-3.5 in) |
| Double / large | Standard or large bun, two patties | 11.5-13.5 cm square (4.5-5.3 in) | 8.5-10 cm (3.3-3.9 in) |
| Smash burger | Thin, wide patties with crisp edges | 12-14 cm square (4.7-5.5 in) | 6.5-8.5 cm (2.6-3.3 in) |
| Gourmet / stacked | Large brioche bun, tall build, skewered | 12.5-16 cm square (4.9-6.3 in) | 9.5-12 cm (3.7-4.7 in) |
US suppliers often quote clamshells in inches (for example 4, 5 or 6 inches); 4 inches is about 102 mm, 5 inches about 127 mm and 6 inches about 152 mm. Check whether a quoted dimension is internal or external, and whether it describes the base or the whole closed box.
How do you measure a burger for a box?
Build the burger exactly as it is served at peak, measure its widest point and its height after it has settled, then add clearance on each side and above. Measure burgers made by different staff: real builds vary more than the recipe card suggests.
A practical method:
- Assemble five to ten burgers of the same item during a normal service, not a test kitchen session
- Measure the widest diameter, including any patty, cheese or lettuce overhang
- Measure height one to two minutes after assembly, when the bun has compressed slightly
- If the burger is wrapped or sits on a liner before boxing, measure with the wrap on
- Take the largest typical measurement, not the average, as the design basis
Then add clearance. As a rule of thumb, allow a few millimetres up to around 10 mm on each side of the footprint and a similar margin above the top of the bun. Too little clearance squashes the bun and stresses the lock; too much lets the burger slide and come apart in transit.
Why do smash burgers need a different box?
Smash burgers are wide and flat. The patty is pressed thin and often extends beyond the bun with crisp, lacy edges, so the footprint is driven by the patty rather than the bun, while height is lower than a classic double. A standard double box tends to be too tall and sometimes too narrow.
For smash burgers, size the footprint to the patty overhang and keep internal height modest so the burger does not move. Many smash builds are wrapped tightly in paper before boxing to hold the stack together; in that case measure the wrapped burger. If the brand serves smash burgers mainly wrapped without a box, the wrap format matters more than the box (see burger wrap and basket liner sizes).
How much bigger is the box on the outside?
It depends on the material. Internal dimensions describe the space the burger occupies; external dimensions add the material thickness and any flaps or locks. The difference is small for board and noticeably larger for corrugated, so two boxes with the same internal size can fit differently in a bag.
| Construction | Approximate wall thickness | Effect on external size |
|---|---|---|
| Folding boxboard, 250-400 gsm | about 0.35-0.6 mm | Minimal; external footprint grows by around 1-2 mm overall |
| F or N flute micro-flute | about 0.5-1.0 mm | Small increase |
| E flute micro-flute | about 1.1-1.8 mm | External footprint grows by several millimetres; check bag and shelf fit |
The front locking tab and rear hinge also add to the closed external depth. If your takeaway bags are sized to hold two or three boxes side by side, check the external dimensions of the closed boxes against the bag base. Bag sizing is covered in takeaway bag sizes, and the board versus corrugated choice in folding board vs corrugated burger boxes.
How does box structure affect usable space?
Two boxes with the same nominal dimensions can hold different burgers, because the structure shapes the cavity. A clamshell with a domed or angled lid gives more height at the centre than at the edges, which suits rounded buns. A clamshell with folded internal corner webs loses a little space at each corner. A tuck-end carton gives a rectangular cavity suited to burgers served flat or in a tray.
When comparing quotes, ask each supplier for a dieline with internal dimensions marked, and request plain samples to test with real burgers. Structural options are covered in burger box structural designs, and dielines generally in packaging artwork preparation.
Which sizing mistakes cause the most problems?
- Sizing to the recipe card rather than to burgers built during a real service
- Comparing external dimensions from one supplier with internal dimensions from another
- Forgetting the wrap or liner thickness when the burger is wrapped before boxing
- Choosing one large box "to fit everything", which lets singles slide and costs more material per order
- Ignoring the bag: boxes that fit the burger but not two-abreast in the standard takeaway bag
- Adding a new printed size for every limited-time burger instead of reusing an existing size
What to send for a sizing review
To size burger boxes accurately, a supplier needs measured burger dimensions, the service mode for each item, and the bags the boxes must fit. Send:
- Each burger with widest diameter and settled height, and whether it is wrapped
- Your current box sizes (internal dimensions) and what goes wrong with each
- Takeaway bag internal base dimensions
- Expected share of each item in total burger sales
- Preferred material and structure, if decided
With that information, proposed sizes can be checked against plain samples at quotation stage. See custom printed burger boxes for the full specification checklist, or send your measurements to 9 Packaging.
