Our classic single wall boxes offer a cost-effective and no-frills packing option that is always reliable, easy to assemble and easy to unpack. While you may think it’s impossible to improve on perfection, these adjustable height boxes offer even more advantages!

These adjustable multi-depth boxes allow you to pack goods securely and simply remove the portion of the box that remains above the level of the product before finalising packing. This allows you to pack various types and quantities of goods more snugly, minimising extra space and the need for excessive packing material.

The adjustable boxes save you money by eliminating the need to buy multiple different-sized boxes, with a single box able to accommodate different delivery types, quantities and sizes. This also provides a saving on packing material and an extra level of security from shocks and bumps as you reduce the margin for the product to move around.  

Simply trim the corners of the box to the desired height and fold them tightly at the marks so that the sides fit snugly around your product.

DISCS ™, the DS Smith industry-leading testing process

DISCS ™ is a DS Smith testing process that determines whether packs can survive the bumps and scrapes of the average e-commerce supply chain. Online orders sometimes need to survive up to 50 touchpoints, so choosing the right pack is an important decision.

If you would like the security of knowing that your boxes will fully protect your product, please contact our Customer Service. We can offer you a DISCS ™ test for your product. Get in touch with us by phone at 0808 1691 030 or e-mail at, and we’ll send you a quotation.


One of the most important principles of the circular economy is designing for circularity, which involves products and services being designed with their end-of-life in mind, making it easier to recover and regenerate materials.

DS Smith has developed a series of circular design metrics which give us an accurate picture of the degree of implementation of circular design principles in the production of our packaging solutions and provide quantifiable data to show how circular a given packaging solution is and allow quick identification of the areas of improvement required.

Our Circular Design Metrics measure Supply Chain Optimisation, Recyclability, Planet Safety, Material Utilisation, Renewable Sources, Recycled Content, the Carbon Footprint and Design for Reuse.

* This circularity information was made by using the information of an average single wall box.
