Single wall cardboard boxes

Buy single wall cardboard boxes online from Boxtopia today. All of these boxes are made from a single sheet of 3mm cardboard, which makes them strong, light and flexible – perfect for postal delivery and holding a wide range of products.

Filter our single wall boxes by shape to find the right one for you. We sell: square boxes (with equal dimensions); short boxes (with a height lower than their length and width); tall boxes (with a height greater than their length and width); and long boxes (with a length greater than their width and height). All the dimensions that you’ll see in these pages are in the format of length x width x height (all in mm) and show the internal measurements of the boxes.

For more information on how to measure your items and find the box that’s right for you, visit our cardboard box size guide.

Can’t find what you’re looking for? Look for heavy duty double wall boxes instead, or design your own box with our box calculator. Get in touch if you have any questions.

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.
