Square double wall boxes

The dimensions for square double wall boxes are all equal (length, width and height). This makes them perfect for packaging products with regular dimensions. As the products below are all made with double-thickness corrugated cardboard, they’re also very sturdy, making them ideal for bulky products or journeys where they’re likely to be handled a lot.

Remember that all of the dimensions for the square boxes below are measured on the inside of the box. This is especially important to remember for double wall boxes, as their board is 6mm thick, which can put your measurements out by over a centimetre if you count on the dimensions being for the outside of the box.  If you can’t find the size you’re looking for, you can make your own box with our box calculator.

FSC Compliant

All the cardboard we use is fully Forestry Stewardship Council (FSC) compliant. Your boxes are made of board with recycled content between 70% to 100% and are 100% recyclable and 100% biodegradable.
