Quick Answer
Moving boxes come in four standard sizes – small, medium, large and extra-large – plus specialty boxes for wardrobes, dishes, TVs and artwork. Choosing the right box size prevents damage, controls weight, and reduces your freight volume for international shipping. For sea freight, correct packing directly affects your container space and your customs documentation.
The right packing box is the foundation of a successful international move. Choose boxes that are too large and you overfill them or waste space. Too small and you end up with twice as many boxes as you need. Wrong box for the item and things break.
This guide covers every moving box size, what fits inside each one, the specialty boxes worth using, and how to apply a packing strategy designed specifically for international sea freight – where your boxes spend weeks at sea before they reach your new home.
Why the Right Moving Box Makes a Bigger Difference Than You Think
Most people think of moving boxes as a minor detail. For an international move, they are not.
✔ Damage prevention — the right box protects fragile items through weeks of ocean transit, not just a 20-minute drive.
✔ Cost control — sea freight is priced by volume. Poorly packed boxes with unused space inflate your cubic metre count and your freight cost.
✔ Customs clearance— a specific, accurate packing list is required for every international shipment. Poorly organised boxes make this harder to write correctly.
✔ Organised delivery — boxes packed by room and labelled clearly mean your new home gets sorted faster at the other end.
💡 Pro Tip: For sea freight from Australia, your boxes will be inside a sealed container for weeks. The ocean environment brings movement, humidity, and temperature variation. Packaging that survives a local move does not automatically survive an ocean crossing. Export-grade materials and correct box selection matter.
Standard Moving Box Sizes - Complete Guide
Here are the four standard box sizes used for household moves in Australia, with real dimensions, weight capacity and what each one is best for.
Box Size | Typical Dimensions | Volume | Weight Limit | Best For |
Small Box | 35 × 35 × 35 cm | ~42 litres | 20–25 kg | Books, DVDs, tools, canned food, heavy kitchen items |
Medium Box | 45 × 45 × 45 cm | ~90 litres | 20–25 kg | Kitchenware, toys, shoes, small appliances, ornaments |
Large Box | 60 × 45 × 45 cm | ~120 litres | 15–20 kg | Pillows, bedding, lamps, light clothing, cushions |
Extra-Large Box | 70 × 55 × 55 cm | ~200 litres | 10–15 kg | Very bulky lightweight items — duvets, large cushions |
💡 Pro Tip: The most common mistake: using large boxes for heavy items. A large box full of books will exceed 30kg and the base will fail. Heavy items always go in small boxes. Lightweight bulky items – pillows, linen, soft toys – go in large boxes.
Specialty Moving Boxes — When Standard Is Not Enough
Standard boxes work for most household items. For fragile, valuable or awkwardly shaped items, specialty boxes exist for a reason. Here is every specialty box type and when to use it.
📚 Book Boxes — Small and Strong What fits: 15–30 books per box depending on size. Reference books, textbooks, hardcovers. 💡 Never mix books with lighter items – keep book boxes dedicated to heavy items only. Always pack spines flat. |
🛏 Linen and Clothing Boxes — Medium What fits: 20–30 folded items. Sheets, towels, t-shirts, lightweight clothing, soft furnishings. 💡 Roll clothing rather than folding – reduces wrinkles and fits more per box. Reserve for items that do not need hanging. |
👔 Wardrobe Boxes — Tall with Hanging Rail What fits: 15–25 hanging garments. Suits, dresses, coats, uniforms. 💡 Use the hanging rail for clothes that crease easily. Fill the base of the box with shoes, accessories or folded items to maximise space. |
🍽 Dish and China Boxes — Double-Walled What fits: 8–12 dinner plates, bowls, mugs, glassware. Best for full kitchen crockery sets. 💡 Layer with cell dividers for glasses. Wrap each plate individually. Pack plates vertically on their edge not flat. Less pressure equals less breakage. |
📺 TV and Electronics Boxes — Custom Sizes What fits: One TV or monitor per box. Electronics, gaming consoles, audio equipment. 💡 Original manufacturer boxes are ideal. If unavailable, a custom-sized box with foam inserts provides equivalent protection for ocean transit. |
🖼 Picture and Mirror Boxes — Flat and Adjustable What fits: Framed artwork, mirrors, glass panels, flat decorative items. 💡 Always use corner protectors. Wrap in bubble wrap before boxing. Label FRAGILE on every face of the box. Carry very large or irreplaceable artwork as hand luggage if possible. |
🍷 Wine and Bottle Boxes — Cell-Divided What fits: 6 or 12 bottles per box depending on configuration. Wine, spirits, olive oil, sauces. 💡 Note: alcohol cannot be shipped in sea freight containers from Australia without appropriate documentation. Check destination country restrictions before packing any alcohol. |
What Can Fit in Each Moving Box - Practical Guide
Here is a practical, room-by-room breakdown of what fits in standard box sizes.
Item Category | Qty per Box | Recommended Box | Notes |
Books (paperback) | 20–30 | Small | Spine flat or upright. Never exceed 20kg. |
Books (hardcover) | 12–18 | Small | Pack tight — no movement inside. |
Dinner plates | 8–12 | Dish box | Vertical. Wrap each individually. |
Glasses / mugs | 8–15 | Dish box | Use cell dividers. Wrap each. |
Clothing (folded) | 20–30 items | Medium | Roll for space efficiency. |
Clothing (hanging) | 15–25 items | Wardrobe box | Hang directly on rail. |
Shoes | 6–10 pairs | Medium | Box them individually or stuff with socks. |
Towels and linen | Full set | Large | Light, bulky — ideal for large boxes. |
Pillows and cushions | 4–6 | Extra-large | One box per room’s worth. |
Small kitchen appliances | 2–4 | Medium | Wrap individually in bubble wrap. |
Books and DVDs mixed | 20–25 | Small | Keep heavy items together. |
Toys (plastic) | 10–20 | Medium | Remove batteries — declare electronics. |
Office supplies | Mixed | Medium | Documents in separate folders only. |
Packing for International Sea Freight - What Is Different
Packing for a local move and packing for an ocean freight shipment are not the same thing. Your boxes will travel inside a sealed container for weeks – exposed to movement, temperature change and humidity. Here is what that means for how you pack.
Weight and Volume Optimisation
Sea freight is priced by cubic metre. Every box with unused space is costing you money. Fill boxes fully – use clothing, towels and packing paper to fill gaps. A box that is 80% full is more expensive than a box that is 100% full when you multiply it across 150 boxes.
At the same time – never exceed weight limits. A burst box at the bottom of a container stack is not recoverable.
Layering Fragile Items Correctly
For ocean transit, fragile items need layers – not just wrapping. The sequence for packing fragile boxes:
✔ Layer 1: 5–7cm of crushed packing paper or bubble wrap on the box base.
✔ Layer 2: Heaviest fragile items first — wrapped individually.
✔ Layer 3: Medium items — each wrapped, gaps filled with paper.
✔ Layer 4: Lightest fragile items on top — with paper or bubble wrap above.
✔ Final layer: 5cm padding before sealing. Box should not flex when pressed.
Labelling for Customs Documentation
Every box needs a label that includes: room destination, general content category, box number, and whether it contains fragile items. This is not just for your convenience — it feeds directly into the customs inventory.
For international moves, the packing list submitted to customs must describe the contents of every box specifically. ‘Miscellaneous household goods’ is not an acceptable customs description. ‘Ceramic dinner plates ×8, crystal wine glasses ×6’ is.
💡 Pro Tip: When professional packers write the customs inventory as they pack, it is specific and accurate by definition. When you pack yourself and try to write the inventory from memory afterwards, it is almost always too vague – which is the most common cause of customs delays.
Items That Should Not Go in Moving Boxes
Some items require separate handling – not because they are prohibited, but because they are better managed differently for safety, compliance or practicality.
Category | Items | Reason |
Important documents | Passports, birth certificates, wills, financial documents | Carry in hand luggage. Never in sea freight. |
Medications | Prescription and controlled medications | Carry with prescription. Controlled meds cannot go in freight. |
Valuables | Jewellery, cash, heirlooms of high value | Carry personally. Insurance on freight covers replacement goods, not irreplaceable items. |
Hazardous materials | Paint, fuel, aerosols, flammable liquids | Prohibited in sea and air freight containers. |
Perishable food | Fresh food, dairy, opened condiments | Will not survive transit. Creates contamination risk. |
Live plants | Any plant or soil | Biosecurity risk. Seized at destination. |
Alcohol (some destinations) | Particularly UAE shipments | Restricted or prohibited at destination. Declare separately. |
⚠️ Note: Prescription medications and controlled substances must be carried in hand luggage with your prescription and a doctor’s letter — not packed in sea freight boxes. Check destination country restrictions before packing any medication.
Smart Packing Tips — From Experience
Declutter Before You Pack – Not While You Pack
Every item you decide not to ship reduces your freight volume and your cost. Go through every room systematically before packing day. Sell, donate or dispose of anything you have not used in 12 months. Packing day is not the time to make these decisions.
Balance Box Weight Across the Shipment
Avoid packing all heavy items in the same layer of the container. Alternate heavy and light boxes in your planning. Your container is loaded from floor to ceiling — heavier boxes go at the base, lighter at the top.
Use a Consistent Labelling System
Label every box on at least three sides — top and two faces. Include: room, brief content description, box number, and FRAGILE if applicable. Colour-code by room using coloured tape or stickers. This dramatically speeds up unpacking and helps identify boxes during customs inspection.
Pack an Essentials Box Last – Unpack It First
One box that contains everything you need for the first 48 hours in your new home: phone chargers, a change of clothes, basic toiletries, important documents copies, kettle, tea or coffee. This box travels with you or is shipped via advance air parcel not in the main sea freight container.
How Many Boxes Do You Need?
Here is a practical estimate based on typical Australian home contents. These are starting points – your actual number will vary based on how much you own and how thoroughly you declutter before packing.
Home Size | Estimated Box Count | Container |
Studio / 1-bedroom apartment | 30–60 boxes | LCL shared container or small FCL |
2-bedroom home | 60–100 boxes | 20ft FCL container |
3-bedroom home | 100–150 boxes | 20ft FCL (full) or 40ft FCL |
4-bedroom home | 150–200+ boxes | 40ft FCL container |
5+ bedroom home | 200+ boxes | 40ft or 40ft High Cube FCL |
💡 Pro Tip: These estimates assume professional packing where boxes are filled efficiently. DIY packing typically produces 20–30% more boxes than professional packing for the same volume of goods because boxes are less consistently filled.
Professional Packing vs Doing It Yourself
Both are valid options and each suits different situations. Here is the honest comparison for an international move.
Factor | Professional Packing | DIY Packing |
Customs inventory | Written simultaneously — specific, correct | Written from memory — often too vague |
Ocean transit packing | Export-grade standards | Domestic removalist standard — not designed for ocean freight |
Insurance coverage | Full coverage applies | May be limited or restricted for owner-packed goods |
Time | 1–2 days for 3BR home | 4–6 days for 3BR home |
Box efficiency | Filled to correct weight and volume | Often underfilled — inflates freight volume |
Cost | Additional service cost | Your time + packing materials |
For international sea freight, professional packing delivers two advantages that DIY cannot easily replicate: ocean-rated packing standards and a customs inventory that is written correctly from day one. When your goods spend weeks at sea, the packing quality matters. When your container arrives at port, the inventory accuracy matters.
Conclusion — Good Packing Is the Start of a Good Move
Choosing the right moving boxes and packing them correctly is not a minor detail. For an international sea freight move from Australia, it affects your freight cost, your customs clearance, your insurance coverage, and the condition of your belongings when they arrive.
The principles are consistent: heavy items in small boxes, fragile items in specialty boxes, everything labelled specifically, nothing left to guesswork. A well-packed container clears customs faster, costs less to ship, and delivers your belongings in the same condition they left.

FAQ's
For most household moves, medium boxes (45×45×45cm) offer the best balance of capacity and manageable weight. Small boxes suit heavy items like books. Large boxes work well for lightweight bulky items like pillows and linen. Specialty boxes - dish boxes, wardrobe boxes, TV boxes should be used for fragile or high-value items.
Yes. A fully loaded box should not exceed 20–25kg. Heavier than this risks the box base failing during lifting, which can damage both the box contents and the items below it. The rule of thumb: if you cannot lift it comfortably with both hands, redistribute the weight across two boxes. |
The kitchen is consistently the most complex room to pack for international moves. Fragile items, odd shapes, heavy appliances and the need for specific layering and padding make it the most time-intensive room. Start kitchen packing early, use dish boxes for crockery, and wrap each item individually. |
A typical 3-bedroom home takes 2–3 full days to pack for international sea freight when done professionally, or 4–6 days for a careful DIY pack. Professional international packing teams work room by room and write the customs inventory simultaneously - which is why their timeline is shorter despite the additional documentation step.
Standard cardboard moving boxes are suitable for most household goods in sea freight containers. For fragile items - glassware, electronics, artwork, mirrors specialty boxes provide additional protection for the weeks of ocean transit. Heavy or high-value items benefit from timber crating. Star Moving uses export-grade packing materials designed specifically for ocean freight conditions.
