How Many Moving Boxes Do You Need? Sizes and a Room-by-Room Guide

If you are asking how many moving boxes do I need, the short answer for most Sussex moves is roughly 15 to 30 for a one bedroom flat, 30 to 50 for a two bedroom, 50 to 80 for a three bedroom house and 80 to 120 for a four or five bedroom. Those are working figures used across the removals trade, and they assume ordinary contents rather than a loft full of paperwork or an unusually large book collection. This guide explains how to turn that rough number into an accurate one for your own home, and which box types you actually need.

Getting the count right matters more than it sounds. Too few and you spend the last two days of packing driving around looking for cartons. Too many and you have paid for boxes you will flat-pack and put in the recycling. If you are still pricing the move itself, our removal costs in Sussex guide sets out where materials sit within a full quote.

Typical box counts by property size

Use these as a starting point, then adjust using the section below:

• Studio or one bedroom flat: 15 to 30 boxes
• Two bedroom house or flat: 30 to 50 boxes
• Three bedroom house: 50 to 80 boxes
• Four to five bedroom house: 80 to 120 boxes
• Larger family house with loft, garage and outbuildings: 120 or more

The spread within each band is wide for a reason. Two families in identical Worthing semis can differ by thirty boxes depending on how long they have lived there and how much is stored in the loft. Length of occupancy is the single best predictor: a household that has been in place fifteen years will need noticeably more than one that moved in three years ago.

The box types and what goes in them

Removal firms work with a small standard range, and using the right type is what keeps boxes liftable and contents intact.

• Small or book carton. Roughly 30 to 40cm on each side. For books, files, records, tinned food, tools and anything dense. A small box full of books is already heavy; a large one is unliftable and will burst.
• Standard or medium carton. Around 45 to 50cm across, the workhorse of the move. Kitchenware, toys, small electricals, contents of drawers.
• Large carton. For bulky light items: bedding, cushions, lampshades, coats, soft toys. Never books.
• Wardrobe or porta-robe carton. A tall box with a hanging rail so clothes travel on their hangers. Allow one per double wardrobe as a rule of thumb, or two for a well-stocked one. Most removers hire these rather than sell them, and collect them afterwards.
• Picture and mirror carton. Flat, telescopic cartons for framed art, mirrors and glass shelving.
• Layflat or crockery carton. Reinforced, sometimes with dividers, for plates, glassware and china. Plates travel on their edge, not stacked flat.

As a rough mix for an average family home, expect around a third small, a half standard, and the remainder large plus the specialist cartons.

Working out your own number, room by room

The quickest accurate method is to walk the house and count in tens. Most rooms fall into predictable ranges.

• Kitchen: 10 to 20 boxes. Usually the highest count in the house and the one people underestimate, because cupboards hide a great deal. Add crockery cartons on top.
• Living room: 6 to 15, more if you have bookshelves or a large media collection.
• Each bedroom: 6 to 12, plus wardrobe cartons for hanging clothes.
• Children's bedroom: 8 to 15, since toys are bulky and awkward.
• Bathroom: 2 to 4.
• Home office or study: 8 to 15, mostly small cartons because paperwork is dense.
• Loft: 10 to 30, and this is where estimates go wrong most often.
• Garage and shed: 5 to 20, plus tools, which are better in crates or toolboxes than cartons.

Add ten per cent to the total. You will find more than you expect, and a spare flat-packed box costs very little compared with the disruption of running out on the final evening.

What else you need alongside the boxes

Boxes are only part of the materials list. For an average three bedroom house, plan for:

• Packing paper: a large pack, or roughly one ream per ten boxes of breakables. Newspaper works but the ink transfers onto crockery.
• Bubble wrap: one large roll, kept for genuinely fragile items rather than used on everything.
• Packing tape: five or six rolls, plus a tape gun. People consistently buy too little tape.
• Marker pens: at least two, ideally with coloured labels for each room.
• Mattress and sofa covers if anything is going into storage.

Many Sussex removal firms sell a materials pack sized to your property, and some will buy back or collect unused flat-packed boxes afterwards. It is worth asking, because it removes the risk of over-ordering entirely.

Where to get boxes

Three routes, each with a trade-off. Buying new from your remover or a packaging supplier gives you consistent sizes that stack safely and survive the journey, which matters if anything is going into storage. Hiring plastic crates is popular for flat moves and short local moves: they stack neatly, need no tape and are collected afterwards, though they cost more for a long booking. Free used boxes from supermarkets, bookshops or local selling groups cost nothing but arrive in mismatched sizes that stack badly, and some will already be weakened. Free boxes are fine for bedding and clothes, less so for anything heavy or breakable.

Whatever the source, keep loaded boxes under about 15 to 18kg. That is roughly what one person can carry down stairs safely, and removers will thank you for it.

Packing rules that save boxes and breakages

A few habits reduce both the count and the damage. Fill every box to the top, using paper or soft items to remove voids, because a half-empty box collapses when something is stacked on it. Keep each box to a single room so unpacking follows the same logic as packing. Label the side as well as the lid, since boxes are stacked and lids disappear. Write the room and a short contents note, not just "misc". Mark fragile boxes clearly on more than one face.

Pack an essentials box last and load it last, so it comes off the van first: kettle, mugs, tea, toilet roll, phone chargers, medication, a change of clothes, basic tools and the paperwork for the move. Our moving house checklist covers the wider timeline, and if you would rather not do any of this yourself, our guide to packing service costs in Sussex explains what a professional pack involves.

When to start collecting

Start acquiring boxes about four weeks before the move and begin packing three weeks out, starting with the loft, the garage and anything seasonal. Aim to have everything except daily essentials boxed the day before. If you are having a full professional pack, do not pre-pack anything without checking first, since some insurance cover applies only to items the removal firm packed themselves.
