How do we measure our boxes?
We work on a general rule of internal = minimum and external = maximum. We measure our boxes ourselves. We measure them as accurately as we can, but they are an approximation, and are there only to act as a guide. Boxes are generally moulded to stack and nest and most will taper towards the bottom of the box.
The internal measurements are the minimum measurements from the bottom of the box, and not always a true reflection of the box volume. We measure them this way so you can see if your item is going to fit in the box.
The external measurements are the maximum measurements of the box, so you can see if the box will fit in a particular space. If you are storing a particular item, we would strongly recommend that you contact us first so we can assist you in making the right choice.
