How many moving boxes do I need?
Pick your number of bedrooms and how long you have lived there, and the calculator shows an indicative box count broken down by type: small, medium, large and specialty (wardrobe and picture boxes). It is built from the thing people get wrong: years in the home, not just floor area, drive the count.
Estimate your moving boxes
Indicative only. Real counts vary with how much you own, so always grab a few spare flat-packed boxes you can return or pass on.
Indicative total
boxes
The mix matters as much as the number: heavy items go in small boxes so each stays liftable, light bulky items in large boxes. A too-big box of books becomes unliftable, splits at the base, and slows the crew on moving day.
Assumptions: base counts of about 28 / 48 / 74 / 101 boxes for a unit, 2-bed, 3-bed and 4-bed home lived in 2 to 5 years; under 2 years trims roughly 15%, over 5 years adds roughly 20% for accumulated belongings; split is about 45% small, 30% medium, 18% large, with the rest specialty.

| Home size | Small | Medium | Large | Specialty | What drives it |
|---|---|---|---|---|---|
| Studio or 1-bedroom unit | 15 | 8 | 5 | 1 wardrobe, a few picture boxes | ~25 to 30 boxes; small flats fill faster than people expect. |
| 2-bedroom home | 25 | 15 | 8 | 2 wardrobe, picture boxes | ~45 to 55 boxes; the kitchen and books drive the small-box count. |
| 3-bedroom house | 40 | 22 | 12 | 3 wardrobe, picture boxes | ~70 to 80 boxes; garages and sheds are the hidden volume. |
| 4-bedroom house | 55 | 30 | 16 | 4 wardrobe, picture boxes | ~100 to 110 boxes; long-term homes can need far more. |
The short answer
How many moving boxes you really need
Moving boxes look like the most trivial part of a move, which is exactly why they catch people out. Almost everyone underestimates how many they need, runs short halfway through packing, then either makes a late-night trip to the shops or pays the removalist for boxes on the day at a premium. The trap is treating box count as a function of home size alone. It is really driven by how long you have lived somewhere, because years in one place quietly fill cupboards, garages and sheds with things you forgot you owned. The second mistake is the mix: load a big box with books and it becomes unliftable, slows the crew you are paying by the hour, and risks a split base. Get the count and the small-to-large mix right up front, source free boxes early, and the whole pack runs faster and cheaper. This page shows how many boxes you actually need, in what mix, and where to get them.
Here is the core takeaway in one line: box count is driven by how long you have lived somewhere as much as by home size, and the small-to-large mix matters as much as the number, so plan both up front and source boxes early. A three-bedroom house typically needs 70 to 80 boxes, but a long-term family home can need far more, because years quietly fill the garage, the shed and the back of every cupboard. Get the mix right (heavy in small, light in large) and a few spares in hand, and you avoid both the late dash to the shops and the removalist's premium on the day.
Reframe the assumption: you are not just sizing a house, you are sizing how much you have accumulated. Count generously, weight the mix toward small boxes for the heavy stuff, grab a few spares you can return or pass on, and start collecting free boxes weeks before the move, not the night before.
The blind spot
Where a quick box estimate leaves you short on the day
Most "how many moving boxes" advice does one of three unhelpful things, and each one ends with you under-supplied halfway through packing.
First, it pins the count to bedrooms alone. A simple "three-bed needs 40 boxes" ignores the variable that actually fills the truck: the years you have spent in the home. Two identical houses can need wildly different counts if one family moved in last year and the other has been there a decade, accumulating tools, toys, paperwork and shed clutter.
Second, it treats every box as interchangeable. Guidance that just gives a total tells you nothing about the mix, so people buy a stack of large boxes, fill them with books, and create boxes no one can lift. The result is split bases, near misses on backs, and a crew slowed down re-taping and repacking, which costs you time and money if you are billing by the hour.
Third, it assumes you will simply buy boxes. It quietly steers you to retail when free boxes are easy to find if you start early. Leave it late and your only fast options are paying full price for new cardboard or buying boxes from the removalist on moving day, which is the dearest way of all.
How a box plan actually works, piece by piece
Expert analysis: counting, mixing and sourcing your boxes
Why years lived, not just floor area, sets the count
Floor area tells you how much space you have to fill, but time tells you how much you actually have. Every year in a home adds a layer: kitchen gadgets, kids' gear, hobby kit, paperwork, garage and shed overflow. That is why two three-bedroom houses can differ by twenty boxes or more. As a working rule, start from the base count for your home size, then add roughly a fifth if you have been there more than five years, and trim a little if you moved in recently. When in doubt, count high; an unused flat-packed box costs nothing to return or pass on, while running short mid-pack costs you a trip or a premium.
The small-to-large mix, and why it is not a detail
The mix is where most plans quietly fail. Small boxes are for dense, heavy items: books, tinned food, tools, crockery and records, because a small box caps the weight at something one person can carry. Medium boxes are the all-rounder for kitchenware, lamps, toys and general goods. Large boxes are only for bulky but light items: doonas, pillows, linen and winter coats. Put books in a large box and you create a load no one should lift, the base splits, and the contents are at risk. A good move is roughly weighted toward small and medium boxes, with large kept for the light bulky stuff, so nothing on the truck is a hazard.
Specialty boxes: wardrobe and picture boxes earn their keep
Two specialty boxes pay for themselves. A wardrobe (porta-robe) box has a built-in hanging rail, so clothes travel on their hangers and go straight into the new wardrobe, saving an hour of folding and refolding. A flat picture box protects mirrors, framed artwork and flat-screen TVs that a standard carton cannot. You only need a handful: a couple of wardrobe boxes for a unit, three or four for a house, plus picture boxes for whatever is flat and fragile. They are the boxes people forget, then improvise badly on the day.
Buy, borrow or hire: the cheapest route is a mix
New boxes cost roughly $2 to $5 each, so kitting out a whole house in fresh cardboard runs into the hundreds. Free second-hand boxes from friends, Gumtree, Facebook Marketplace and local shops (Big W, Target, Kmart, bookshops and bottle shops) cover most of your needs for nothing. Reusable plastic crate hire is sturdier and often cheaper for a single move, with delivery and collection, though you usually have only a couple of weeks before they are due back. The cheapest plan is a blend: mostly free boxes, a few new ones for fragile and heavy items, and hired crates if your timeline is tight.
What this looks like in real moves
How the box miscount plays out across Australia
The points above are not theory. They are exactly how households end up making extra trips, breaking things, or paying more than they planned:
The mid-pack run to the shops
A couple grab 20 boxes for their two-bedroom flat, confident it is plenty. They run out with the kitchen and the wardrobe still to go, and make a late-night dash to buy more at full retail. A generous count and a few spares up front would have cost less and saved the trip.
The unliftable box of books
A renter fills a large box with paperbacks because it was the box on hand. It is too heavy to carry safely, the base gives way on the stairs, and a stack of books and a chipped mug hit the landing. Small boxes for the heavy stuff would have avoided the lot.
The removalist box premium
A family leaves boxes to the last week, runs short, and buys the rest from the removalist on moving day at a marked-up price, with the crew waiting and the clock running. Sourcing free boxes a few weeks earlier would have been free and unhurried.
The damp garage boxes
A mover reuses a stack of boxes stored in a damp garage without checking them. A soft base collapses under crockery in transit. A quick check for damp and weak bases, plus a few new boxes for fragile items, would have kept everything intact.
The insider insight
Start early and the boxes cost you nothing
Here is the part most packing guides skip. The price of boxes is set almost entirely by your timeline, not by the boxes themselves. Start three to four weeks out and free boxes are everywhere: friends and workmates who just moved, full bundles given away on Gumtree and Facebook Marketplace, and sturdy cartons that shops break down every day. Start the week of the move and that supply is closed to you, leaving only new cardboard at full price or, worst of all, boxes bought from the removalist on the day while the crew you are paying stands and waits.
The non-obvious truth: boxes are not really a shopping cost, they are a planning cost. The households that pay nothing for boxes are not the ones who found the cheapest shop, they are the ones who started collecting early, counted generously, and weighted the mix toward small boxes for the heavy items. Plan the count and the mix weeks ahead and the boxes look after themselves.
The practical consequence: do not leave boxes to the last minute. Work out your count and mix now, put the word out and watch the marketplaces for a fortnight, keep a few new boxes for fragile and heavy items, and you will rarely pay full price, let alone the removalist's premium.
Grounded in the analysis
What you should actually do about moving boxes
Specific moves that follow from how box count, mix and timing really work, not generic advice.
Count generously, by years not just rooms
Start from the base count for your home size, add about a fifth if you have lived there more than five years, then grab a few spares you can return. Running short mid-pack costs a trip or a premium; an unused box costs nothing.
Weight the mix toward small boxes
Heavy and dense items (books, tins, tools, crockery) go in small boxes so each stays liftable; keep large boxes for light bulky things like doonas and pillows. Add a few wardrobe and picture boxes for clothes and flat fragile items.
Source free boxes early, buy new only where it counts
Three to four weeks out, ask friends and watch Gumtree, Facebook Marketplace and local shops. Check second-hand boxes for damp and weak bases, buy a handful of new boxes for fragile and heavy items, and hire crates if your timeline is tight.

The bottom line
Why the box count is a planning job, not a shopping one
Moving boxes are the easiest part of a move to get wrong, because the instinct is to grab a few and start. The households that pack fastest and cheapest do the opposite: they count by years as much as by rooms, weight the mix toward small boxes for the heavy items, add a couple of wardrobe and picture boxes, and start collecting free boxes weeks ahead so they never pay the removalist's premium on the day. Plan the count and the mix up front, source early, keep a few spares, and the boxes stop being a last-minute scramble and become the part of the move you have already solved.
Common questions
A Selectra expert answers your moving box questions
As a rough rule, a studio or one-bedroom unit needs about 25 to 30 boxes, a two-bedroom home around 45 to 55, a three-bedroom house roughly 70 to 80, and a four-bedroom house 100 or more. Those are base figures for someone who has lived in the home a few years. The single biggest variable is not floor area, it is how long you have been there, because years quietly fill garages, sheds and wardrobes. If you have lived somewhere five years or more, add roughly a fifth to the count. It is always cheaper to have a few spare flat-packed boxes you can return or pass on than to run short and pay the removalist for boxes on moving day.
You want a deliberate mix, not all one size. Small boxes are for heavy, dense items: books, tinned food, tools, records and crockery, because a small box keeps the weight liftable. Medium boxes are the all-rounder for kitchenware, toys, lamps and general household goods. Large boxes are only for bulky but light things: doonas, pillows, linen, soft toys and winter coats. The classic mistake is filling a large box with books; it becomes too heavy to lift safely, splits at the base, and slows a crew you may be paying by the hour. Add a few specialty boxes too: wardrobe (porta-robe) boxes with a hanging rail so clothes travel on their hangers, and flat picture boxes for mirrors, artwork and TVs.
Plenty of places, if you start a few weeks early. Ask friends, family and workmates who have moved recently, since they are usually glad to clear the boxes out. Check Gumtree and Facebook Marketplace, where people give away post-move boxes for free or a few dollars, often as a full bundle. Ask at local shops: Big W, Target, Kmart, bookshops and bottle shops break down sturdy cartons daily and will often put some aside if you ask. Supermarkets can help too. Just check second-hand boxes for damp, mould and weak bases before you trust them with anything valuable, and buy a handful of new boxes for fragile or heavy items where structural strength matters.
It depends on how soon you will move again and how much effort you want to spend sourcing free boxes. Buying new costs roughly $2 to $5 a box, so a three-bedroom move in fresh cardboard can run a few hundred dollars. Hiring reusable plastic crates is often cheaper for a single move and far sturdier, with companies delivering and collecting them, though you usually have only a couple of weeks before they are due back. The cheapest route of all is a mix: free second-hand boxes for most things, a few new boxes for fragile and heavy items, and hired crates if your timeline is tight. Plan it early and you rarely need to pay full retail.
Because an overpacked box is slow, risky and can cost you money. A box crammed with books or tins can weigh more than is safe to lift, which strains backs and tempts people to drag or drop it. Heavy boxes split at the base, spilling and breaking the contents inside. And if your removalist bills by the hour, a crew wrestling unliftable boxes and re-taping split ones is burning time you are paying for. The fix is simple: heavy items go in small boxes, light bulky items in large ones, keep each box to a weight one person can carry comfortably, and tape the base across the seam for support.
Start three to four weeks out. Free boxes take time to source, since you are relying on what friends, marketplaces and shops happen to have, and the good bundles on Gumtree or Facebook Marketplace go quickly. Starting early also lets you pack non-essentials gradually instead of in a last-minute scramble, which is when boxes get overpacked and mislabelled. Box hire needs a delivery slot booked ahead too. Leave it to the last week and your only fast option is buying new at full price or paying the removalist for boxes on the day, which is the most expensive way to get them.
