If you are planning a move, one of the most overlooked but critical decisions you will make is choosing the right size of moving boxes. It sounds simple, right? Just grab a few boxes and start packing. But here is the truth: using the wrong size box can lead to broken items, back pain, wasted space, and even higher moving costs.
In this blog by Book a Mover, we are going to walk you through everything you need to know about box sizes and how to use them correctly. Whether you are moving for the first time or just want to avoid past mistakes, this guide is written for beginners in clear, friendly language. Let us get packing!
Why Box Size Actually Matters
Imagine putting all your books in one huge box. Sure, it fits everything in one place, but when you try to lift it, your back says “no, thank you.” Now imagine packing fragile glassware into a box that is way too big. Even with padding, everything moves around and risks breaking.
The size of your box determines:
- How safely your items will travel
- How easy it is to carry
- How efficiently you use your space
So, choosing the right box size is not just about convenience. It is about protection, cost, and peace of mind.
Understanding the Most Common Box Sizes
Let us break down the typical box sizes used in moving and what they are best for:
1. Small Boxes (Around 40 x 30 x 30 cm)
Best for: Books, tools, canned goods, small appliances, fragile items (when packed tightly)
These boxes are deceptively strong. Because they are smaller, you can pack heavy items without making them too difficult to lift. Movers often call them “book boxes” for a reason.
Use small boxes for dense, heavy items. They are easier to lift and less likely to break under the weight.
2. Medium Boxes (Around 60 x 40 x 40 cm)
Best for: Kitchen items, shoes, toys, electronics, clothes
These are your “everyday” boxes. Medium boxes strike a balance between size and weight, making them the most versatile option for general household packing.
According to Moving.com, most households use more medium-sized boxes than any other type.
3. Large Boxes (Around 75 x 50 x 50 cm)
Best for: Bedding, pillows, lampshades, large but lightweight items
Do not be tempted to fill these with heavy objects. A large box packed with books becomes unmanageable fast. Keep it light and bulky.
Overfilling large boxes with mixed items. Stick to soft, light contents only.
4. Extra-Large Boxes (Around 90 x 60 x 60 cm)
Best for: Comforters, duvets, bulk clothing, artificial plants
These boxes are great for soft items that take up a lot of room. They are less commonly used but very handy for big, light things you do not want to squish.
Speciality Boxes Worth Knowing About
Wardrobe Boxes
Tall boxes with hanging bars inside. No need to fold your dresses or suits—just transfer them directly from the closet.
Dish Packs
Thicker-walled boxes with dividers. Perfect for glassware, plates, mugs, and other fragile kitchen items.
TV or Picture Boxes
Flat, expandable boxes that protect large screens or artwork with padding and support.
A 2023 report by HireAHelper found that damages to TVs and framed art made up over 14% of insurance claims in household moves. A specialty box reduces that risk significantly.
How Many Boxes Do You Need?
This is the next big question, and the answer depends on your home’s size and how much you own. To give you a general idea, here is an estimated breakdown:
| Home Size | Small Boxes | Medium Boxes | Large Boxes |
| Studio Apartment | 10–15 | 8–12 | 3–5 |
| 1–2 Bedroom Home | 15–25 | 20–30 | 10–15 |
| 3–4 Bedroom Home | 30–40 | 35–50 | 20–25 |
Add a few extra for wardrobe and specialty boxes if needed. It is better to have a few left over than run out the night before moving day.
Matching Items to the Right Box: Simple Packing Tips
Heavy items = Small boxes
Think books, tools, canned food. Keep it compact and sturdy.
Light and bulky = Large boxes
Think bedding, blankets, and pillows. Fill the space without adding weight.
Fragile items = Divided or cushioned boxes
Always pad delicate items with paper or bubble wrap and place them snugly to prevent shifting.
Put heavier items at the bottom of the box and lighter ones on top. This helps prevent items from being squashed and ensures the box stays firm when piled with others.
How to Choose Boxes Like a Pro (Even as a Beginner)
1. Plan by room
Break down your packing room-by-room. It is easier to estimate needs and stay organized.
2. Order more than you think
You will always need more boxes than you expect. Allow about 10–15% extra just in case.
3. Stick to uniform sizes
It makes loading the truck easier. If all your boxes are roughly the same size, they stack better and reduce wasted space.
4. Do not skimp on quality
Reusing boxes is eco-friendly, but make sure they are clean, dry, and structurally sound. A weak box can cause costly accidents.
5. Label everything clearly
Use a thick marker and label on multiple sides. Add “FRAGILE” if needed and which room it belongs to.
What Most People Get Wrong About Moving Boxes
- Packing all heavy items in large boxes.
- Using worn-out boxes for fragile items.
- Not reinforcing the bottom with packing tape.
- Mixing too many item types in one box (leads to confusion).
- Not sealing boxes properly.
Even small packing errors can cause items to break, create unnecessary hassle, and slow things down on your moving day. lanning carefully at this stage can spare you a lot of stress and last-minute scrambling down the line.
Where to Find the Right Moving Boxes
Once you have figured out the right box sizes for your move, the next step is finding out where to source them.
Here are a few smart places to source moving boxes, whether you are on a budget or looking for convenience:
1. Local Removalist Companies
Many moving companies sell moving kits or individual boxes, often tailored to home sizes. The benefit? You can be sure the boxes are strong enough for the job—and sometimes you even get free delivery.
2. Packing Supply Stores
Specialised stores (both physical and online) stock all types of moving boxes, including wardrobe, dish packs, and TV boxes. This is your best bet for speciality items and high-quality materials.
3. Online Marketplaces
Websites like Amazon, eBay, and Officeworks offer bundle packs of small, medium, and large boxes. Look for sets labeled “double-walled” or “heavy-duty” for extra protection.
Bonus tip: If you are moving in Australia, Bunnings and Storage King are popular and reliable suppliers of packing boxes.
4. Recycling Groups and Local Giveaways
Check Facebook Marketplace, Gumtree, or local “Buy Nothing” groups. Many individuals are happy to pass on their used moving boxes once they have completed their own move.
Just make sure the boxes are clean, dry, and still sturdy.
5. Supermarkets and Retail Stores
You can often find sturdy small or medium boxes at local supermarkets, bookshops, or bottle shops—they are usually glad to let you take a few off their hands.
These are perfect for lightweight or non-fragile items but avoid using them for anything valuable or breakable.
Final Thoughts: Think Inside the Box
Choosing the right box size might seem like a small detail in the big picture of moving, but it makes a huge difference in how smoothly everything goes. You will pack faster, lift easier, avoid damage, and save space in your moving vehicle.
So before you grab whatever box is lying around, take a few minutes to think strategically. Your back—and your breakables—will thank you.
