What Size Moving Boxes Do I Need? A Complete Sizing Guide

Choosing the wrong box sizes is one of the most common (and costly) moving mistakes. Too many large boxes and you'll be lugging back-breaking loads of books across the driveway; too few small ones and you'll run out halfway through the kitchen. Getting your box sizes right from the start saves you money, time, and a sore back on moving day.

Here's everything you need to know about picking the right moving boxes for every room in your home.

The Golden Rule of Box Sizing

Before we get into specifics, remember this one rule: heavy items go in small boxes, light items go in large boxes. A small box packed with books is manageable. A large box packed with books is a recipe for a split carton and a trip to the chiropractor.

Keep this in mind as you read through the sizes below, and you'll already be ahead of most people on moving day.

Small to Medium Boxes (50L) – Your Everyday Workhorse

This is the standard moving carton most people picture when they think "moving box," and it's the one you'll want the most of.

Best for: books, vinyl records, tools, tinned pantry goods, small kitchen appliances, files and folders

Because they're compact, these boxes keep heavy items at a manageable weight even when fully packed. They're also brilliant for filling awkward gaps in the moving van.

Have a look at our Cardboard Moving Boxes Medium 50L - prices start from just $6, so it's easy to stock up without blowing the budget.

Large Boxes (90L) – The All-Rounder

If small boxes are for heavy things, large boxes are for everything in between - not too heavy, not too light, but bulky enough that it'd take forever to pack in a small box.

Best for: pots and pans, small electronics, shoes, toys, bathroom items, decor

Take a look at our Moving Cardboard Packing Boxes 90 Litres (580 x 385 x 355mm), available in pack sizes from 5 right up to 50.

Tea Chest Boxes (100L) – The Classic All-Purpose Box

Taller and roomier than a standard carton, tea chest boxes are a moving day staple. If you're not sure what size to grab for general packing, this is usually it.

Best for: bedding, lampshades, lightweight kitchen items, kids' toys, general odds and ends

We stock a few different versions depending on what you need:

Extra Large Boxes (150L) – For Light, Bulky Items Only

These boxes look tempting because of how much they hold, but use them for the wrong thing and you'll regret it. Save these strictly for items that are big but light.

Best for: pillows, cushions, soft toys, clothing, lampshades

Check out our 5 x Large Cardboard Packing Boxes 150 Litres (550 x 550 x 500mm).

Cube Boxes (Double Wall) – Extra Strength for Awkward Items

A square shape with double-wall construction means these boxes are sturdier than your average carton and stack beautifully - perfect for items that need a bit more protection.

Boxes With Handles – For Your "Often Used" Items

Anything you'll be carrying yourself, loading in and out of the car, or unpacking on day one deserves a box with built-in handles.

Best for: essentials boxes, kitchen items, anything you need quick access to

Specialty Boxes for the Tricky Stuff

Not everything fits neatly into a square. For these items, a purpose-built box will save you a world of damage and frustration:

How Many Boxes Do I Actually Need?

A handy rule of thumb based on home size:

  • 1 bedroom apartment: 15-25 boxes
  • 2 bedroom home: 30-45 boxes
  • 3 bedroom home: 50-70 boxes
  • 4+ bedroom home: 70-100+ boxes

If you'd rather not do the maths yourself, our Cardboard Moving Packing Boxes - 1 Bedroom to 4 Bedroom Packs take the guesswork out completely - pre-bundled with the right mix of sizes for your home, with same-day postage.

A Few Common Mistakes Worth Avoiding

  • Overloading large boxes with heavy items - this is how boxes split open mid-carry
  • Underestimating how many you need - always order 10-15% extra
  • Mixing too many random sizes - consistent sizes make stacking and loading the truck much easier
  • Forgetting the awkward stuff - mirrors, TVs, and bikes need their own boxes, not just bubble wrap
