Simply measure the length, width and depth (height) of what you’d like to pack – this will give you the internal dimensions for your box. We recommend expressing the dimensions in millimetres, as this is an industry standard.
The length and width measurements should relate to the opening of the box. The dimensions of a box are usually provided in this order:
- Depth (height)
For example: 800mm x 400mm x 100mm.
If you need a fitting inside your box, you should allow an extra 3mm per measurement. The external dimensions of your box will then depend upon the type of board used – for example single or double wall cardboard.
