These 457 x 457 x 457 mm double wall boxes are part of our square range. They’re ideal for items with standardised dimensions which tend to be slightly heavier, where the double wall is needed for support.
Check out our cardboard box size guide for more guidance on measuring your items and figuring out which box that's right for you.
You don’t have to stick to our shop sizes if you can’t find what you’re looking for. Use our box calculator to get quotes for your own bespoke box size. Box printing services are also available, allowing you to add your logo or other individualisation to your boxes.

Boxtopia is committed to delivering your boxes as quickly as possible. It usually takes just a few days to make boxes from our stock board although, subject to workload, we can often supply products on a next day delivery if necessary. For larger quantities of boxes, it is more cost effective for us to buy the board in cut to size so that we can make the boxes without any waste material. Typically, we can despatch these within a week. If you have a deadline, just check with us first.
Important note: our delivery prices are valid for the UK mainland only.
