How to Choose the Right Moving Boxes
The boxes you pick can make or break your move. Get it right and everything arrives safe and sound. Get it wrong and you're nursing a bad back and broken crockery. Here's everything you need to know.
01 Single Wall vs Double Wall — Which Do You Actually Need?
Before you think about sizes, you need to understand what the box is actually made of. The wall thickness of your cardboard determines how much punishment it can take.
Single Wall
Made from one layer of corrugated fluting sandwiched between two flat sheets. Fine for light, non-fragile bits and bobs, but not built for heavy lifting or stacking.
- Clothing and soft furnishings
- Soft toys and cushions
- Light bedding and linens
- Short-distance moves
Double Wall
Two layers of corrugated fluting with BC fluting profile, delivering roughly 60% more strength than single wall. The proper choice for a house move.
- Books, kitchenware, electronics
- Fragile and heavy items
- Long-distance moves or storage
- Safe to stack in vans and units
Bottom line: Double wall boxes cost only marginally more than single wall, and they're far better at protecting your belongings and holding their shape when stacked. For a house move, always go double wall. You can browse our full range of boxes and protective covers to see what's available.
02 Standard UK Box Sizes and What Goes In Each
There's no universal standard, so a "large" box from one supplier might be a "medium" from another. Always check the actual dimensions. That said, UK removal companies generally work with four core sizes.
| Size | Typical Dimensions | Capacity | Best For | Max Weight |
|---|---|---|---|---|
| Small | 450 × 450 × 250mm | ~1.5 cu ft | Books, tools, tins, small appliances | ~20kg |
| Medium | 450 × 450 × 500mm | ~3 cu ft | Kitchenware, toys, clothes, shoes | ~20kg |
| Large | 450 × 450 × 750mm | ~4.5 cu ft | Bedding, pillows, lampshades, linens | ~20kg |
| Extra Large | 610 × 460 × 610mm | ~6 cu ft | Duvets, cushions, bulky winter coats | ~15kg |
Key point: These boxes are designed to fit through standard UK doorways and allow you to wrap your arms around them safely. That's not a coincidence — removal companies settled on these dimensions decades ago for exactly that reason.
03 The Golden Rule: Heavy Items, Small Boxes
It sounds counterintuitive, but it's the single most important thing to get right.
Heavy items go in small boxes. Light items go in big boxes.
Packing heavy books into a large box makes it nearly impossible to lift and massively increases the chance of the bottom giving way. Keep each box under 20kg and your back (and your boxes) will thank you.
What this looks like in practice
Small boxes should hold your heaviest items: hardback books, magazines, vinyl collections, canned food, hand tools, and small kitchen appliances like toasters or food processors.
Medium boxes are your all-rounders. Use them for kitchenware, crockery (well-wrapped), toys, shoes, bathroom products, and general household bits.
Large and extra-large boxes are for bulky, lightweight items only: bedding, pillows, cushions, soft furnishings, towels, and winter coats. Even though there's loads of space, resist the urge to fill them with heavy gear.
Watch your back. Back injuries are one of the most common problems on moving day, especially for DIY moves. If you can't comfortably lift a box with both hands and walk with it, it's too heavy. Take something out.
04 Specialty Boxes for Awkward Items
Standard boxes handle most of a house move, but some belongings need something purpose-built. These specialty options are worth every penny for the protection they offer.
Wardrobe Boxes
Tall boxes with a built-in hanging rail. Keeps suits, dresses, and coats crease-free. Most hold around 20 garments, with space at the bottom for shoes and accessories.
Dish Pack / China Boxes
Extra-thick double-wall construction with internal dividers. Designed specifically for plates, bowls, glassware, and mugs. Massively reduces the risk of breakages.
Picture & Mirror Boxes
Flat, telescopic boxes that adjust to fit framed artwork, mirrors, and flat-screen monitors. Two interlocking pieces create a snug, custom-sized shell.
TV Boxes
If you've lost the original packaging for your flatscreen, these adjustable boxes accommodate various screen sizes (32" to 70") with room for protective wrapping.
Archive / File Boxes
Sized for A4 documents, lever-arch files, and folders. Typically hold up to 12kg and have reinforced handles. Ideal for home offices.
Custom / Odd-Shape Boxes
For musical instruments, antiques, or anything that doesn't fit a standard box. Telescopic or made-to-measure options are available from specialist suppliers.
Worth knowing: Purpose-built boxes typically cost a bit more, but they're designed to give the exact protection your items need. For high-value or fragile belongings, they're well worth the investment.
05 How Many Boxes Will You Need?
This varies wildly depending on how much stuff you own, but here are some rough estimates based on property size. These assume an average amount of belongings — adjust up if you're a collector, down if you've had a good declutter.
A useful rule of thumb is to budget for roughly 10–15 boxes per room, then add a few extra for the kitchen (which almost always needs more than you think) and any loft or garage items. It's always better to have a few spare boxes than to run out mid-pack.

06 Essential Packing Materials
Good boxes are only half the battle. You'll also need the right materials to keep everything secure inside them.
Your packing essentials kit
- Strong packing tape (not sellotape)
- Bubble wrap for fragile items
- Packing paper or tissue paper
- Permanent markers for labelling
- Scissors and a utility knife
- Cable ties for loose wires
For fragile items like glassware and china, wrap each piece individually in packing paper or bubble wrap before placing it in the box. Fill any remaining gaps with scrunched-up paper or towels to stop things shifting in transit. For a deeper dive into technique, have a read of our guide on tips for packing moving boxes.
Money-saving tip: Towels, tea towels, and clothing can double as padding. Wrap fragile items in soft garments to save on bubble wrap and make better use of box space.
07 Packing Tips That Actually Matter
Your Packing Checklist
- Reinforce the base. Double-tape the bottom of every box before you start filling it. This is especially important for heavy boxes — one layer of tape is never enough.
- Don't leave empty space. Gaps let items shift and collide during the move. Fill voids with packing paper, bubble wrap, or soft clothing.
- Label everything. Write the contents and destination room on at least two sides of each box. Your future self will be extremely grateful when unpacking.
- Mark fragile boxes clearly. Use a different colour marker or write "FRAGILE" in large letters on all sides so anyone handling the box knows to take extra care.
- Pack room by room. This keeps things organised and makes unpacking far more efficient. Don't mix kitchen items with bedroom stuff.
- Pack an essentials box last. Kettle, mugs, tea bags, phone charger, toilet roll, basic cleaning supplies, snacks. Load it last so it comes off the van first.
- Test-lift before sealing. If you can't comfortably carry the box a short distance, it's too heavy. Remove something before taping it shut.
- Start early. Begin packing 4–6 weeks before moving day. Start with rooms and items you use least, and leave daily essentials until the last couple of days.
08 Common Mistakes to Avoid
Using any old box you can find. Supermarket fruit boxes and random Amazon packaging might be free, but they're rarely the right size, they're inconsistent for stacking, and they won't protect your belongings properly. For a house move, invest in proper moving boxes — they're not expensive and the difference is enormous. This goes double if you're moving long distance, whether that's across Surrey, over to the Isle of Wight, or all the way to Northern Ireland — your boxes need to hold up for the journey.
Overpacking large boxes. A large box stuffed with books is dangerously heavy and the bottom is almost guaranteed to fail. Save big boxes for bulky, lightweight items only.
Skipping the tape on the base. The factory fold on the bottom of a flat-pack box is not enough on its own. Always reinforce with at least two strips of strong packing tape, forming an H-shape across the base.
Not using enough padding. Items rattling around inside a box are items getting damaged. Wrap fragile things individually and fill every gap. A box should feel firm and snug when you give it a gentle shake.
Leaving it all until the last minute. Rushing your packing is a recipe for poorly packed boxes, forgotten items, and unnecessary stress. Give yourself several weeks and do a room at a time.
One last thing: Always buy 10–15% more boxes than you think you'll need. You'll almost certainly use them, and having spares beats a last-minute dash to the shops on moving day.
