We have a range of box shapes – some small and cube-shaped, others large and thin. The number after ‘BX’ doesn’t always tell you how big a box is, and height varies, even for large boxes.
We’ve grouped all boxes into easy-to-understand sizes.
You might have noticed different product codes and names – we’ve listed them below – plus suggestions on what might fit in each size, tips on how to measure and postage.
