Cardboard boxes for the job.
Start with what you are packing, the space it needs and how it will travel. Then compare the construction and quantity.
Which type of cardboard box do you need?
| Your job | Start here | Check first |
|---|---|---|
| Sending products | Shipping boxes | Internal fit, protection and finished parcel size |
| Smaller online orders | Postal boxes | Closure style and external dimensions once packed |
| Moving home | Moving boxes | Manageable loads, room labels and pack contents |
These uses overlap. A box described as a shipping carton may also suit a home move. Choose using its actual specification and the contents you need to pack.
What size cardboard box should I choose?
Measure the contents together with their chosen protection and compare that arrangement with the usable internal dimensions. Small, medium and large are seller labels; they are not consistent measurements across suppliers.
Use our box size guide and calculator to work out the internal space. For posting, check the packed external size separately against your carrier’s limits.
Single wall, double wall and strength
Wall count describes the board’s construction. It does not give a universal load limit. Ask for the actual board specification and relevant performance information for the size and packing method you plan to use.
Our single versus double wall guide explains the layers and the questions to ask before choosing.
How do I compare box prices?
Check the number of individual boxes in each pack. Compare the delivered order cost on the same VAT basis, including any tape, inserts or protection you need to buy separately. A lower pack price can still mean a higher cost per box.
What about recycled content and reuse?
Check the product’s material information rather than assuming every brown box has the same recycled content or certification. Keep usable boxes dry for reuse and follow your local collection guidance when recycling them. Our product-specific material details will be published with the confirmed range.
