Choosing the right takeaway paper bag size is one of the most common — and most avoidable — problems faced by Australian cafes and takeaway businesses. A bag that is too narrow for a burger box creates a fumbling, awkward handover. An oversized bag makes a single coffee and muffin look lost inside. A bag that is too short for a stack of containers tips at the handle. Every one of these problems adds friction at the counter and costs money through damaged stock and wasted packaging.
Matching container dimensions to the correct bag size solves all of these issues. This guide covers how to measure bags correctly, which dimensions matter most for takeaway use, and which takeaway paper bag sizes best fit the most common food containers used in Australian cafes, restaurants, and takeaway businesses.
Why Takeaway Bag Sizing Matters
The right bag size is not just a logistical detail — it directly affects the customer experience, staff efficiency, and your packaging costs.
Food presentation and container stability. A bag sized correctly for its contents keeps containers upright, reduces the chance of lids popping during transport, and prevents soup, sauces, and hot drinks from spilling inside the bag. A standard takeaway bag should be selected based on container width, depth, and height rather than volume alone.
Carrying convenience. A bag that is significantly oversized creates a floppy, difficult-to-carry package. A well-fitted bag is easier for customers and drivers to handle — handles sit at the right height, the base supports the weight, and the bag does not swing or collapse.
Packaging efficiency and cost control. Stocking the wrong sizes means your team reaches for the largest bag available when the right one is not in reach. Oversized bags cost more per unit and consume more storage space. Using the correct bag size helps reduce packaging waste and improve operational efficiency.
Customer satisfaction. A neatly packed bag is a small but genuine signal of care. In a competitive café market, presentation details accumulate into the overall experience customers remember and repeat.
Understanding Takeaway Bag Dimensions
Before selecting a bag, it helps to understand what the three measurements on a product listing actually mean — because confusing them is the most common source of sizing mistakes.
Width is the horizontal measurement across the front face of the bag. It determines how wide an item can sit inside the bag without pressing against the sides.
Gusset (Depth) is the side-to-side measurement of the base — how deep the bag is from front panel to back panel when open. This is often the most important measurement when fitting takeaway containers. A container that is wider than the bag's gusset will tip sideways inside the bag. Standard takeaway bags should have a gusset of at least 14cm to 18cm to accommodate clamshell containers and burger boxes without tipping.
Height is the vertical measurement from the base to the top of the bag opening. It needs to be tall enough for the container — plus any stacking — to sit below the top of the bag without pressing against the handles or tipping out.
How Smartbag lists dimensions: Product listings display dimensions as Height × Width × Depth (HxWxD). Always check all three before ordering — a bag can look large enough by height but have a gusset too narrow for your containers.
The practical rule: measure your most common container at its widest point, add at least 2–3cm of clearance, and match that to the bag's width and gusset. Stack-height should sit at least 3–4cm below the top of the bag.
Common Takeaway Containers Used in Australian Cafes
Understanding the dimensions of standard containers helps match them to the right bag. The following are the most common container formats found in Australian cafes, restaurants, and takeaway operations.
Burger boxes. Standard single burger boxes are typically 12–15cm wide × 12–15cm deep × 8–10cm tall. Gourmet burger boxes can be slightly larger. A combo meal with a burger box and chips cup adds both width and height requirements.
Bio and kraft lunch boxes. The most common sizes are 500ml (approximately 16cm × 11cm × 6cm), 750ml (approximately 19cm × 13cm × 6cm), and 1000ml (approximately 22cm × 15cm × 7cm). These are the standard format for café lunch offerings, meal prep services, and takeaway counters.
Salad bowls and noodle containers. Round containers range from 500ml to 1000ml, with diameters typically between 12cm and 18cm. The circular footprint requires a gusset wide enough that the bowl base can sit flat without rocking.
Clamshell containers. Popular for sandwiches, wraps, and light meals. Typically 18–23cm wide × 13–16cm deep × 5–8cm tall. The wide base of a clamshell is the measurement that most often catches businesses out — the gusset needs to match.
Coffee cups with lids. A standard 8oz takeaway cup with lid stands approximately 10–11cm tall and 7–8cm in diameter. A 16oz cup is approximately 14–15cm tall and 9–10cm in diameter. Cup carriers with two or four drinks require significantly more gusset width.
Pastry and bakery items. Individual pastries, slices, and scrolls can often be wrapped or boxed. A standard café slice box is typically 12–14cm wide × 8–10cm deep × 5–6cm tall.
Bakery boxes. Larger bakery boxes for cakes or multiple items vary widely but commonly sit in the 25–35cm wide × 20–28cm deep range — requiring a large bag with a substantial gusset.
Smartbag Takeaway Paper Bag Size Guide
Smartbag stocks two distinct takeaway bag formats. Understanding which is appropriate for your operation matters before selecting a size.
Twisted handle takeaway bags (Small, Medium, Large) are the most common format for over-the-counter café and restaurant service. These are made from 100–120gsm recycled kraft paper with reinforced twisted paper handles. Available in brown and white kraft. Suitable for in-store pickup and counter service where presentation matters.
Flat handle SOS takeaway bags feature an extra-wide block bottom, reinforced flat handles, and are specifically engineered for delivery platforms (Uber Eats, Menulog, DoorDash) where the flat handle can be stapled shut for tamper-evident sealing. These carry containers flat and are the standard choice for delivery operations.
Both formats are available in custom printed versions with full-colour printing in 7–10 working days from artwork approval.
Size Reference Table
| Bag Size | Approx. Dimensions (H × W × D) | Best Container Types |
| Small | ~28–30cm × 22–24cm × 14cm | Single burger box, one bio lunch box (500–750ml), 2 x coffee cups, pastry bag orders |
| Medium | ~32–34cm × 26–28cm × 16cm | Burger + chips combo, 1–2 x 1000ml lunch boxes, single clamshell + extras, salad bowl orders |
| Large | ~38–42cm × 32–36cm × 20–22cm | Multiple meal containers, large clamshell or noodle bowl + drinks, family-size orders |
Note: Always verify exact dimensions on the product listing before ordering. Dimensions can vary slightly between product runs. Use the gusset (depth) measurement as your first filter — it is the dimension most likely to cause fit issues.
Which Bag Fits a Standard Burger Box?
A standard single burger box (approximately 12–15cm wide × 12–15cm deep × 8–10cm tall) fits comfortably in the Small takeaway bag. The gusset on a Small takeaway bag (approximately 14cm) is wide enough for the box to sit flat, and the bag height keeps the box well below the handles.
Single burger only: Small bag. The box fits cleanly with room for a folded serviette and a sauce portion cup beside it.
Burger and chips (separate cup): Medium bag. The combined footprint of a burger box plus a tall chips cup requires both the additional width and height of the Medium. A Small bag will hold both items but may be tight across the gusset depending on the chips cup diameter.
Combo meal with two containers: Medium bag. Two standard containers side by side require a gusset of at least 14–16cm to keep them flat. Medium bags comfortably accommodate this.
Double burger order or large gourmet burger box: Medium or Large. Premium burger boxes from specialty burger restaurants are often 18–20cm wide — a dimension that exceeds the Small bag's gusset. Always measure your specific box before assuming a size fits.
The gusset dimension is often the most important measurement when fitting takeaway containers into bags — and burger boxes are the most common example where businesses get this wrong by ordering based on height alone.
Which Bag Fits Standard Bio Lunch Containers?
Bio and kraft lunch boxes are the staple container for café lunch menus, meal prep services, and quick-service restaurants. The correct bag size depends on the container volume.
500ml bio lunch box (approx. 16cm × 11cm × 6cm): Fits in a Small bag with room for a sauce, napkin, and cutlery bundle. The Small bag's gusset comfortably clears the 11cm container depth.
750ml bio lunch box (approx. 19cm × 13cm × 6cm): Fits in a Small bag. The 13cm depth sits inside the Small gusset with adequate clearance. If including cutlery and a sauce portion, the Small remains appropriate.
1000ml bio lunch box (approx. 22cm × 15cm × 7cm): Sits at the upper limit of a Small bag in terms of gusset fit. A Medium bag is the safer choice for 1000ml containers, particularly if any additional items (napkin, sauces, cutlery pouch) are included in the order.
Two 750ml or 1000ml containers stacked or side by side:Medium bag. Two full-size lunch boxes need the Medium's additional gusset width to sit properly without tipping or pressing against the bag walls.
Three or more containers:Large bag. Multiple containers for family orders or group catering require the Large format's combination of width, gusset depth, and height.
Which Bag Fits Coffee and Pastry Orders?
The coffee and pastry combination is the highest-volume order type in Australian cafes — and it is also one of the most commonly under-bagged, because the individual item dimensions look small but the combined order does not fit neatly in the bag.
Single pastry or slice (unwrapped): A Small bag handles individual café pastries comfortably. Croissants, scrolls, and slice portions all fit within the width and gusset of the Small without bending or crushing.
Two or three pastry items:Small bag for flat items (slices, brownies, biscuits). Medium for a mix of upright items (croissants, muffins, scrolls) where height and gusset space is needed to avoid crushing.
Coffee and pastry combo (2 x cups + pastry):Medium bag. Two takeaway cups side by side, even in a cardboard carrier, require a gusset of at least 16cm to sit flat and stable. Add a pastry item and the Medium is the correct fit.
Café bakery box (6–12 assorted pastries): Large bag. A standard bakery box for six or more items is typically 25–30cm wide and requires the Large bag's gusset and width to accommodate it without squashing the contents.
Morning tea or event catering order:Large bag, or multiple Medium bags if the order spans multiple boxes. For catering-quantity orders, using correctly sized bags for each separate container is better than trying to combine everything in one oversized bag.
Which Bag Fits Family Meal Orders?
High-value family and group orders require careful bag selection. Under-bagging causes structural failure under load; over-bagging causes contents to shift and tip.
Family meal for 2 (2 x main containers + sides):Large bag. Two 1000ml lunch boxes plus two side containers sit across the Large bag's gusset without tipping. The height allows the full container stack to clear the handles.
Family meal for 4 (multiple containers, drinks, extras): Multiple Large bags, divided by container type. Attempting to combine four main containers into a single bag — even a Large — creates instability. Two Large bags, each carrying two mains plus sides, handles the weight and keeps containers flat.
Large catering orders: Multiple Large bags or flat-handle SOS bags in Large format. SOS bags with a 220mm gusset are specifically designed for wide plastic delivery containers and are the preferred format for high-volume delivery operations. Many cafes achieve better efficiency by stocking multiple takeaway bag sizes rather than relying on a single universal option — and for family-order businesses, the Large bag is a non-negotiable part of that range.
Common Sizing Mistakes Cafes Make
Choosing bags based on height only. The most common error. A bag can be tall enough for a container but have a gusset too narrow for it to sit flat. Always check gusset first, then height.
Ignoring gusset dimensions entirely. Many operators look only at width × height on the product listing and overlook the depth (gusset) column. For most takeaway containers — particularly clamshells, burger boxes, and bio lunch boxes — the gusset is the critical measurement.
Using one bag size for all products. A single bag size creates two problems simultaneously: it is too large for small orders (poor presentation, wasted material) and too small for large orders (containers wedged, handles under stress). Stocking Small, Medium, and Large allows staff to match the bag to the order every time.
Overestimating container sizes from memory. Container dimensions vary between suppliers. When a new container format is introduced, measure the actual box before reordering bags. A 2cm difference in a container's base width can mean the difference between a bag that works and one that tips.
Not accounting for extras. Sauce portions, napkins, cutlery pouches, and condiment sachets add width and height to an order. If the bag fits the container exactly with no clearance, it will not fit the container plus extras. Build 2–3cm of clearance into your size selection for every order type.
Ordering a single size in bulk to avoid stocking multiple SKUs. Simplifying to one bag size feels efficient but creates operational problems across the board. The correct approach is to audit your most common container combinations, identify the two or three bag sizes that cover them, and stock each size in appropriate quantities.
How to Build an Efficient Bag Size Range
Most Australian cafes and takeaway operations can cover their full menu with two or three bag sizes. Here is a framework for working out which sizes you need.
Step 1 — Audit your containers. List every container your business uses: burger boxes, bio boxes, clamshells, cups, bakery boxes, side containers. Measure each one at its widest point (width and depth/gusset) and note the height.
Step 2 — Group products by size. Sort your containers into clusters: small (single items, under 500ml), medium (standard single meals, 500–1000ml), and large (multi-container orders, family meals, catering). This gives you your size range.
Step 3 — Match containers to bag sizes. Using the size guide above, identify which Smartbag takeaway size fits each cluster. Test the fit physically before ordering — place the container inside a sample bag and check that it sits flat, that the handles clear the top, and that there is room for extras.
Step 4 — Minimise unnecessary SKUs. You rarely need more than three sizes. A Small for café counter orders, a Medium for standard meal orders, and a Large for multi-container orders covers the majority of Australian café and restaurant menus. Resist the temptation to add extra sizes unless a specific product genuinely requires it.
Step 5 — Test real-world fit under service conditions. Pack a bag as it would leave your counter: container, sauce, napkin, cutlery. Check whether it fits cleanly, whether the handles carry the weight without stress, and whether the bag maintains its shape in a delivery bag or customer's hands.
Why Correct Sizing Reduces Packaging Costs
Over-ordering on large bags to avoid running out of the right size is one of the most common hidden packaging costs in the hospitality sector. The financial case for correct sizing is straightforward.
Fewer damaged bags. A bag overfilled with a container that does not fit properly creates pressure on the gusset seams and handle attachment points. Bags that tear at the counter or during delivery are a direct cost — and an embarrassment.
Reduced per-order packaging spend. A Large bag used for a single-container order that should have gone in a Small costs more per unit and conveys less professional presentation. Right-sizing eliminates this waste.
Better storage efficiency. Bags of one size packed flat take up the same space as bags of two or three sizes stocked in appropriate proportions — but the mixed range means staff are not improvising with the wrong size.
Improved ordering efficiency. When you know exactly which bag you need for each menu section, reordering becomes predictable. You stop running short on the popular size because you have been unconsciously compensating for it with the large.

FAQ
What size takeaway paper bag do I need? Select your takeaway bag size based on the width and gusset (depth) of your largest container, not just the height. The bag's gusset must be wide enough for the container to sit flat without tipping. A Small bag suits single meal containers up to approximately 750ml. A Medium suits standard single-meal orders with extras. A Large suits multi-container family and group orders. See Smartbag's full takeaway paper bag range for dimensions.
Which bag fits a burger box? A standard single burger box (12–15cm wide × 12–15cm deep) fits comfortably in a Small takeaway bag. A burger-and-chips combo requires a Medium. Large gourmet burger boxes (18–20cm wide) also need a Medium to ensure the box sits flat inside the bag without wedging against the sides.
Which bag fits a bio lunch container? A 500ml bio lunch box fits in a Small bag. A 750ml container fits in a Small with room for extras. A 1000ml container is best suited to a Medium bag, particularly when including sauce, napkin, and cutlery. Two or more containers of any size require a Medium or Large.
How do I measure a takeaway paper bag? Takeaway bags are listed by Height × Width × Depth (HxWxD). Height is the vertical measurement from base to opening. Width is the horizontal measurement across the front face. Depth (gusset) is the side-to-side base measurement — how deep the bag is when fully open. Always check the gusset measurement first when fitting containers.
Should cafes stock multiple bag sizes? Yes. Most cafes achieve better efficiency by stocking two or three sizes rather than relying on a single universal option. A Small for café pastry and single-item counter orders, a Medium for standard meal orders, and a Large for multi-container family or delivery orders covers the majority of menu combinations without excessive SKU complexity.
What is the most popular takeaway bag size for Australian cafes? The Medium takeaway bag is the most versatile size for Australian cafes and covers the widest range of standard menu combinations — a single main container with extras, burger-and-chips combos, and two-cup coffee orders. Most businesses that stock only one size choose Medium, but adding Small and Large significantly reduces packing friction across the full menu range.
