What Size Cardboard Boxes are Best for Moving?

Jul 21, 2021 | 0 comments

Figuring out what size cardboard boxes you’ll need when moving home can be a challenge.

We look at popular box sizes and types, as well as what to consider when ordering boxes for your move. All quoted sizes are length x width x height.

Our favourite box size for moves

A good medium-sized box that isn’t too big or small is our stock 6 cardboard box. It measures 610 mm x 450 mm x 300 mm with a capacity of 81 litres.

The box holds a decent amount without becoming too heavy and unwieldy.

The box is available in single- and double-wall box types.

The type you choose should depend on the maximum weight capacity you need. Single-wall stock 6 boxes can hold up to about 12 kg. For items likely to be heavier than that, the double-wall stock 6 box is a stronger, sturdier option.

General guidelines for choosing moving box sizes

Ensure the boxes you’re ordering can handle the weight of the items you want to pack or they might split or break when lifted. Double-wall boxes can handle more weight and are less prone to buckling if squashed.

Don’t make any of the packed boxes heavier than 20 kg or they’ll be too difficult to move. Any boxes over 12 kg should be carried by at least two people. Alternatively, use a moving trolley to avoid back injuries.

Take note of the dimensions when ordering boxes. A box might be large enough in capacity for your needs, but if the width or length don’t fit the items you need to pack you’ll end up with space-wasting gaps.

Smaller cardboard boxes for heavier items

If you need to back heavy items like hardcover books or sensitive items like electronics, choose small, sturdy boxes that can handle the weight and are manageable.

Ecobox stocks the following manageable sizes in single and double wall:

  • stock 4 single wall (300 mm x 230 mm x 300 mm)
  • stock 4 double wall (300 mm x 230 mm x 300 mm)
  • stock 5 single wall (450 mm x 300 mm x 300 mm)
  • stock 5 double wall (450 mm x 300 mm x 300 mm).

For fragile items, consider using our Ecoboxes. These sturdy plastic moving boxes have a lid, are stackable and won’t collapse. They’re eco-friendly and can be rented by the week.

Large cardboard boxes for bulky items

Our largest single-wall cardboard boxes are ideal for bulky items that aren’t too heavy. This includes duvets, blankets, pillows, cushions, soft toys, coats and large hats.

Our range of larger boxes includes:

  • TVL 12 (500 mm x 400 mm x 780 mm)
  • TVL 9 (500 mm x 400 mm x 655 mm)
  • TVL 6 (500 mm x 400 mm x 450 mm).

Specialised cardboard boxes

Ecobox also stocks a range of specialised moving boxes.

Archive boxes

Archive boxes work well for books, files and electronics because they’re sturdy and have their own handles. Archive boxes measure 430 mm x 325 mm x 320 mm and can hold five lever-arch files.

Flatscreen TV boxes

Our flatscreen TV box measures 1,360 mm x 815 mm x 220 mm and will accommodate most standard screens. Some moving companies won’t take your TV without a TV box.

Wardrobe boxes

Our wardrobe box measures 530 mm x 480 mm x 990 mm and comes with a metal bar, so your clothes can hang during transit. This means you don’t have to fold and pack them – and they won’t get wrinkled or damaged.
