40–104 L moving box sizes in Australia: dims and what to pack

Small, medium (standard carton), large (tea chest) and extra-large cover almost every household move, and the rule that separates a smooth day from a sore back is simple: heavy items go in small boxes, light bulky items go in large ones. Get that pairing wrong and you end up with cartons you can’t lift or boxes so empty they crush under their own weight. The exact dimensions, litres and what to actually pack in each size are below.

TL;DR:

• Heavy items like books and tools must go in small boxes to ensure they are safely liftable, while light, bulky objects should be packed in large or extra-large boxes.
• Measuring for the right box size requires adding padding allowance, checking internal dimensions, and respecting weight limits, or you risk damaging items or prolonging the move.
• Most households need between 15 and 70 boxes depending on room count, with a suggested extra 10 to 15 percent to avoid shortages on moving day.
• Specialist boxes for crockery, wine, and wardrobe items improve safety, but proper internal protection is crucial for fragile, expensive, or awkwardly shaped goods.
• Proper stacking and load distribution on the truck relies on consistent, appropriately sized boxes, with heavy items on the floor and voids filled with soft materials for stability.

Quick moving box sizes reference: dimensions and what to pack

Before you order anything, it helps to see the four standard sizes side by side. Suppliers describe boxes slightly differently, some by external measurements, some by internal, so treat these as a working guide rather than gospel and always check the product page before buying in bulk.

These figures come from Find a Mover’s dimension guide, which is a solid baseline for what most Australian box suppliers stock. Kennards Self Storage frames the same sizes by litre range rather than millimetre, pegging small boxes at 20 to 30 litres for heavy items, medium at 40 to 50 litres for general household goods, and large at 100 to 110 litres for bulky but light contents. The two ways of describing the same boxes are worth knowing, because you’ll see both when you’re comparing suppliers.

What actually goes in each size matters more than the number on the box. Here’s how it breaks down in practice:

• Small boxes: books, canned pantry items, tools, small appliances like toasters or blenders, wine bottles with dividers, anything dense that adds up in weight fast.
• Medium boxes: kitchenware, crockery with padding, toys, folders and files, shoes, small ornaments, general odds and ends from a spare room.
• Large (tea chest) boxes: linen, doonas, pillows, lampshades, soft toys, cushions, anything that’s bulky in shape but light on the scale.
• Extra-large boxes: only for the lightest of bulky goods, such as large soft furnishings or bedding sets, because anything with real weight in a box this size becomes unmanageable to carry.

On carrying advice, the standard used across the industry is straightforward. A packed small box shouldn’t feel like a gym session, and if you’re struggling to lift a medium box off the floor with your knees bent and back straight, it’s overloaded regardless of what the label says it holds. There’s no universally agreed maximum weight figure for household cartons the way there is for postal parcels, but the practical test removalists use is: if one person can’t comfortably lift and carry it for 20 metres, split the contents across two boxes.

Specialised moving boxes: crockery, wine, wardrobes and more

Standard cartons handle most of a house, but certain items need purpose-built packaging or they’ll arrive damaged. Specialised boxes cost more per unit, but the alternative is often a broken television or a chipped dinner set, which costs a lot more than the box.

• Crockery boxes: shorter and squarer than a standard carton, usually fitted with cardboard cell dividers so plates, bowls and glasses don’t touch each other in transit.
• Wine cartons: divided into 12 or 15 individual cells, sized specifically for bottles standing upright, which stops them rolling and clinking against each other.
• Port-a-robe (wardrobe) boxes: tall boxes, often close to a metre high, with a built-in metal or cardboard hanging rail so clothes travel on their hangers instead of being folded and creased.
• Flat TV boxes: slim, wide format boxes designed to hold a television upright and rigid, usually paired with foam corner protectors and a layer of bubble wrap.
• Picture and mirror boxes: adjustable telescoping cartons that extend to fit different frame sizes, used with cardboard sheets on both faces of the glass.
• Archive boxes: smaller, reinforced boxes built for paperwork and lever arch files, sized to stay liftable even when packed with dense paper.
• Cube boxes: oversized square cartons for awkward, bulky items like lampshades, that don’t suit the length of a standard carton.

The insert or cushioning matters as much as the box itself. Crockery and wine boxes are close to useless without their dividers, picture boxes need rigid board on both sides of the glass, and TV boxes need foam corners, not just bubble wrap alone. If you’d rather build your own protection for smaller fragile pieces, our guide to packing fragile items safely walks through the DIY approach step by step. For higher-value pieces such as jewellery or watches, specialist advice on secure packaging for luxury items is worth a read before you improvise with towels and tape.

The general rule: buy the specialist box when the item is fragile, expensive, or an awkward shape that a rectangular carton can’t handle safely. For anything else, a well-packed standard box with decent packing materials does the job just as well.

How do you pick the right box size?

Choosing correctly comes down to measuring properly, understanding what the box dimensions actually refer to, and respecting the weight rule. Skip any of the three and you’ll be repacking boxes the night before the truck arrives.

1. Measure the item at its widest, longest and tallest points. Don’t measure the resting footprint; measure the maximum dimension in every direction, because that’s what determines whether it clears the box opening.
2. Add allowance for padding. If you’re wrapping the item in bubble wrap or packing paper, add roughly 20 to 50mm per side to your measurement before comparing it to the box.
3. Compare against the box’s internal dimensions, not the external ones. Suppliers often list external measurements on the box itself, and the walls of a heavy-duty carton can eat 10 to 20mm off each internal edge. Australia Post’s own product guidance flags this gap and recommends checking the product page rather than assuming.
4. Apply the weight rule before you tape it shut. Heavy, dense items belong in small boxes. Light, bulky items belong in large boxes. Never the reverse.
5. Check the box isn’t overfilled or underfilled. A lid that won’t sit flat means it’s overpacked and structurally weak at the top; a box with visible slack means contents will shift and rattle in transit.

Pro Tip: Never mix box sizes randomly on a stack. A run of mismatched heights creates pressure points that crush the smaller boxes underneath, and it’s one of the most common reasons crockery arrives cracked even when it was packed well.

How many moving boxes do you actually need?

Box counts scale with bedrooms, not square metreage, and most people underestimate by a wide margin on their first move. Industry guidance from packaging suppliers puts typical ranges at:

• 1-bedroom apartment: 15 to 25 boxes
• 2-bedroom home: 30 to 45 boxes
• 3-bedroom house: 50 to 70 boxes
• 4+ bedroom house: 70 to 100 or more boxes

These ranges assume a mix of small, medium and large cartons rather than one size for everything, plus a handful of specialised boxes for crockery, wine or wardrobe items where relevant. The same guidance recommends ordering 10 to 15% extra on top of your estimate, and that buffer earns its keep every single time. Running short on box day means a rushed trip to the hardware store while the truck idles outside, or worse, wrapping loose items in bin bags because nothing else is left.

If you’d rather work from volume than room count, a rough method is to tally up your total litres of belongings by walking through each room mentally, then divide by the litre capacity of your preferred box size. A 2-bedroom home with a moderate amount of furniture and belongings typically works out to somewhere between 1,200 and 2,000 litres of packed contents. Our moving checklist breaks this down room by room if you want a more precise starting figure than the rules of thumb above.

Packing and stacking for an efficient moving day

The reason professional movers reach for consistent box sizes isn’t habit, it’s physics. Uniform dimensions build stable, load-bearing layers in the back of a truck, which means weight distributes evenly and boxes lower in the stack don’t bear uneven point-loads from odd shapes above them. A truck packed with random box sizes wastes space in the gaps between them, and every gap is a chance for something to shift on a corner.

A few habits make the biggest difference on the day itself:

• Heavy boxes go on the floor of the truck, light boxes stack on top. Reversing this crushes anything fragile underneath within the first few kilometres.
• Fill voids with soft items. Cushions, towels and bedding pack neatly into gaps between furniture and stop boxes sliding during transit.
• Secure the load with blankets and straps, particularly on furniture and anything tall, so vibration doesn’t work items loose over a long drive.
• Label every box with its contents and destination room. “Kitchen, glassware” tells the unloading crew exactly where it goes and how carefully to handle it, and it saves you hours of guesswork at the other end.

Pro Tip: When you’re deciding between box sizes for a big load, lean toward more medium boxes and fewer extra-large ones. Medium cartons stack tighter, carry easier through doorways and hallways, and give the truck’s load layout far more flexibility than a handful of oversized boxes that only fit one way.

Where to buy moving boxes and what postage sizing means

Standard and specialised boxes are easy enough to find without overpaying, but where you buy them depends on whether you’re moving locally or posting individual items separately. New boxes cost more than reused ones, but they’re stronger and more reliable for anything fragile or heavy, so it’s worth buying new for crockery, books and anything valuable, and saving reused boxes for linen, toys and lightweight goods.

Buying tips worth following before you commit to a supplier:

• Check listed internal dimensions, not just the box name, since “large” means different things between suppliers.
• Buy in packs rather than single units, which almost always works out cheaper per box.
• Confirm stock levels before moving week, particularly for specialised boxes like wardrobe or TV cartons, which sell out faster during peak moving periods.

If you’re posting individual items rather than moving a whole household, Australia Post’s flat-rate packaging is worth knowing about. For parcels 5kg or under, postage is charged by size tier rather than weight, across extra small, small, medium, large and extra-large categories, with prepaid boxes and satchels available in each tier. That can work out cheaper than weighing and pricing an item individually, provided it actually fits the tier you’re paying for.

How EasyMove Services approaches box sizing on real jobs

On a genuine moving day, box sizing isn’t a spreadsheet exercise, it’s the difference between a truck that loads once and one that needs repacking halfway through. Load plans are built around consistent carton sizes precisely because uneven stacks slow everyone down and increase the risk of damage in transit.

Fragile and high-value items get matched to the right specialised box rather than squeezed into whatever’s on hand, and the same care applies to NDIS-compliant moves, where predictable packing and clear labelling matter just as much as careful handling. Real-time tracking on the truck can help take some of the guesswork out of a process that’s already stressful enough without wondering where your kitchen box ended up.

Common box sizing mistakes and how to fix them

Three mistakes account for most of the packing problems removalists see on the day. The first is putting books or tools into large tea chest boxes because “there’s room”, which produces a box nobody can lift safely. The fix is simple: dense items always go small, no exceptions. The second is underfilling large boxes so the sides cave in under stacking pressure, solved by filling gaps with soft linen or towels rather than leaving air space. The third is skipping the internal dimension check on specialised boxes, which leaves people trying to force a flat-screen TV into a box that’s a centimetre too narrow.

Before moving day, run through this quick check: heavy items in small boxes, light bulky items in large ones, every box labelled by room and contents, specialised boxes bought early rather than the week of the move, and 10 to 15% extra stock on hand. That short list catches almost every avoidable mistake before it happens.

What size boxes does Australia Post sell?

Australia Post sells mailing and parcel boxes grouped into small, medium, large and extra-large tiers, with example external dimensions listed on each product page, and it recommends checking internal measurements before packing anything precisely sized.

What are the standard dimensions for packing boxes?

Common examples are small at roughly 403 x 301 x 330mm, medium at roughly 406 x 298 x 431mm, and large or tea chest at roughly 431 x 406 x 596mm, though exact figures vary slightly between suppliers.

How do I know what box size to use for heavy items?

Always put heavy, dense items like books and tools in small boxes, and reserve large or extra-large boxes for light, bulky items such as linen and pillows, since this is the packing rule most Australian moving guides agree on.
