How many boxes do you need for a move?

It is the first question anyone about to move asks, and almost everyone gets it wrong in the same direction: too low. Not out of carelessness, but because when you look at your home you see the furniture, and furniture does not go into boxes. What fills them is everything else: the drawers, the wardrobes, the shelves, the larder, the storage cupboard. Exactly the things you are not looking at.

An estimate to start from

As an order of magnitude:

• Studio or one-bedroom flat (monolocale or bilocale): 20 boxes
• Two-bedroom flat (trilocale): 35 boxes
• Large home, three bedrooms or more: 50 boxes

These numbers are for a home lived in by one or two people, with an average amount of belongings. From there you adjust.

It helps to spell out what "average" means, because that is the part that always slips: a home with no cellar, no collection of anything, where nobody works from home with papers and equipment, and where you have lived for a few years rather than fifteen. If even one of these conditions is not true for you, the base estimate is a starting point, not an answer.

What really moves the count

How many people live there. Two people in the same two-bedroom flat have more than twice the belongings of one person: clothes, shoes and books double, and then you add the things nobody throws away because they are "the other person's".

How long you have lived there. Someone who has lived in a home for eight years has accumulated far more than someone who arrived last year, for the same floor area. Time is a silent multiplier.

Whether you have a cellar, garage or loft. This is the most underestimated factor of all. They are the spaces nobody counts when estimating, because you do not walk through them every day, and they are also the ones holding the bulkiest things.

What kind of things you own. A home full of books fills many more boxes than a home of the same size without a bookcase. Books are heavy and take up volume: if you have a lot of them, count them separately.

Whether someone works from home. A home office does not show up in the floor area, but it exists: monitor, cables, ring binders, supplies. It shifts the count more than it seems.

How to count room by room

The most reliable way to get an idea is not to look at the home as a whole, but to walk through it with a sheet of paper and count the closed spaces: drawers, shelves, cupboard doors, ledges. Those are what end up in a box once emptied.

A rough but useful rule: one full wardrobe shelf, or one metre of loaded bookcase, is worth about one box. A large drawer of clothes, roughly the same. A drawer of cutlery and utensils is less, but it adds up with the others in the kitchen.

The walk goes like this: you go into a room, open everything, including the high cupboards you have not reached in months and the space under the bed, count the full shelves and drawers, and write the number next to the name of the room. Then you move on to the next one. At the end you add it all up and put on a safety margin of about 15%, because in every home there is a category of objects that escapes the count: shoes, cables, medicines, photos, board games.

Two warnings. First: do not count the furniture, count what is inside it. A six-door wardrobe is not "a wardrobe", it is six shelves plus the drawers. Second: hanging clothes do not follow the same rule. Coats and long garments are often better moved on their hangers, inside bags, because folding them and then ironing them all again is time you do not get back.

The kitchen deserves its own count

The kitchen is the room that fills the most boxes of all in relation to its floor area. On its own it can take a quarter of the total, and the reason is that it has the highest density of objects in the home: in a few square metres there are hundreds of pieces, many of them fragile.

The point almost nobody considers is that plates and glasses take up more than their own volume: they also take up the volume of the padding around them. A twelve-piece dinner service, packed properly, needs far more space than it does in the sideboard. If you count the kitchen "by eye", looking at the closed cupboard doors, you get it badly wrong.

How to break it down, in practice:

• Plates and glasses go on their own, because they are heavy and need handling with care.
• Pots and pans are the lucky case: they are hollow. Fill them with tea towels, cloths and utensils and you easily save a box on the total.
• The larder: the one that fills more than expected. Jars, tins, flour, spices. It pays to start months ahead, eating what you have instead of buying more, so that by the end you are moving half of it.
• Small appliances: awkward, bulky shapes. If you kept the original packaging, use it.
• The "odds and ends" drawer: every home has one and nobody can estimate it. Give it a box of its own and stop thinking about it.

Two precautions that save trouble: liquids (oil, vinegar, cleaning products) go into a sealed bag before they go into a box, because a cap that works loose in the van ruins everything else. And the kitchen gets packed last, because you use it right up to the final day: if you have not set aside the boxes you will need for it, you end up packing plates in a hurry, which is exactly when they break.

If you are moving in two stages

It happens often: you have the keys to the new home before leaving the old one, or you are waiting for some work to finish, or one of you moves first. In that case the total count does not change, but how you split it does.

The typical mistake is to divide by room: "this time I take the bedroom, next time the kitchen". It works badly, because in the meantime you have to live. The split that holds is a different one: what you will not need in the coming weeks goes straight away, what you use every day stays. The first wave takes books, out-of-season clothes, the cellar, decorations, sports equipment. The second wave is the bare minimum, which is always bulkier than you think: kitchen, bathroom, bed, work things.

In practice the first wave is bigger than you planned and the second is never just leftovers. Count on a realistic split of around 60/40, not 80/20.

If you rent your boxes, keep one thing in mind: the rental period has to cover both waves, not just the first. It is a trivial detail that makes the difference between a calm move and a race.

If you declutter first, how much does it change

Less than 20%, almost always. It is a counter-intuitive figure, and it helps to avoid illusions.

The reason is that what actually gets thrown out during a move is small in number and large in bulk: a sagging sofa, a broken bike, three big boxes of stuff from the cellar. These free up space in the van, not in the boxes. Clothes, books, crockery and paperwork, the things that actually fill the boxes, are far harder to throw away, because every piece needs a small decision.

This does not mean it is not worth doing. It means it has to be done before, not during. Decluttering while you pack is the thing that slows you down most: you open a box of photos, you stop for half an hour, and by evening you have packed three shelves. If you decide to lighten the load, give it separate sessions in the weeks before, and allow for the real timescales of getting rid of things: bulky waste collection has to be booked, donation points have opening hours, flea markets need you there in person.

And an honest caveat: thinning things out saves you less on boxes than it does on time and on the effort of unloading. That is where you notice the difference.

Typical estimating mistakes, by type of home

Studio, student or first home. Always underestimated, with the phrase "but I do not have much stuff". That is true of the furniture, not of the objects: the kitchen and bathroom of a studio contain more or less the same things as those of a two-bedroom flat.

Couple in a one-bedroom flat. The problem is duplicates. Two sets of pans, two toolkits, two shelves of books with some titles in common. If you have merged two homes, count as if you had one and a half.

Family with small children. Toys are the surprise. They are bulky, light, irregular in shape and take up far more boxes than their weight suggests. A child's bedroom can be worth as much as the main bedroom.

Home lived in for more than ten years. Here the risk is concentrated in the cellar, the loft and the paper archive. Do not estimate them without opening them: it is almost always double what you remember.

Furnished rental. The mistake is the opposite: you overestimate, because you are looking at furniture and appliances that are not yours and that you do not have to move. Count only your own things, and you will find you need much less.

The three most common mistakes

Estimating with the doors closed. The most widespread, and it applies to every type of home: you look at a room from the doorway and pull out a number. But what fills the boxes is inside the furniture, not in front of it.

Putting off the count until you "get started". The estimate has to be done before you order, not the day you open the first box. It is the only moment when you can still adjust without it costing you anything.

Under-filling the large boxes. People who worry about weight fill them halfway, and end up using twice as many. Books and heavy things go at the bottom, the rest on top: a full box is more stable than a half-empty one, which caves in when you stack it.

Better too many than too few, within reason

When in doubt, the next size up is always the better choice. Running out of boxes halfway through packing means stopping, going out, and buying cardboard in a rush the day before the move, which is when it costs the most, in money and in nerves.

With rental this reasoning is simpler than with buying: one extra box that goes back empty is not a problem, while a cardboard box bought and never used just sits there. Cangubox are rigid and designed to be used and reused for a long time, so the safety margin is not wasted material: it is just capacity you did not need to use.

The only case where overdoing it is a nuisance is space at home. Empty boxes waiting to be filled take up a corridor, and if you take far more than you need you live with them for a few weeks. The right margin is the one that covers you against surprises, not the one that turns your living room into a warehouse.

If you do not want to do the sums by hand

On the site you will find a configurator that, with four questions (how big your home is, how many people are moving, how much stuff you have, whether there is a cellar too), tells you how many to start from. It is not a scientific measurement, it is a way of not having to think about it.

If you would rather look straight at the available combinations, the kits are here. And if you are between two sizes, the advice is the same as before: take the larger one.
