Build your custom cardboard box
At Boxtopia, we’re specialists in customising cardboard boxes and packaging, so it’s only natural that we give our customers absolute freedom to create the exact box they need. We allow you to take every design factor into consideration, helping you to create fully personalised packaging boxes. Not only can you alter the size of the box, but the type, cardboard thickness, and colour (single wall only), too.
When you’re happy with your box design, simply add the quantity you require (*up to 200 boxes) to your cart! Play around with the calculator to test different configurations and find the one that works best for your requirements and budget.
*Any quantity over 200 will require a bespoke price so please feel free to contact us directly on firstname.lastname@example.org
Measure the length, width and height of the item in millimetres.
Note: if you use bubblewrap this may add up to 20 mm to the size of the finished item, depending on how much wrap is used.
Add up to 5 mm to the length, width and height to allow for manoeuvrability. The final dimensions will be internal measurements for the box
Enter the chosen dimensions into Boxtopia’s Box Calculator or phone our office for recommendations.
Just wanted to say thank you so much for the boxes – absolutely perfect for storing our Xmas trees
Thanks for that. I appreciate your help with my telescopic box.
I thought you might like to know what the box is for so I enclosed picture of the ‘artwork’ that is to be transported to an exhibition in Chester.
Hello, Just a quick word to say how impressed I am with the sleeves we ordered from you recently. We are not huge users of custom packaging but we have had three 0411 orders from another box company in the last year and yours is much superior both in the quality of the board and the accuracy of the folds. I’m sure we’ll be doing more business with you in future.
Hi, A quick note to confirm that I received my boxes yesterday – and I would like to say thank you. My intended contents fit perfectly into each box (very satisfying).
Thanks again. I look forward to making future orders.

Our standard style custom cardboard boxes are quick to assemble whilst offering great protection for your goods when sealed up with parcel tape. 0201 boxes are perfect for packaging goods safely for shipping or storage. The simple economical design with top and bottom flaps make the box both strong and rigid, and easy to put together. We can custom make this industry standard packing box to provide the perfect fit for your products.
The 0203 is an alternative box type to the 0201 that gives the whole structure even more rigidity and is ideal for fragile goods that require more protection. Instead of meeting in the middle, the flaps on the top and bottom each fold all the way across the box. The 0203 also looks neater than the 0201 if a very small custom box is required. The overlap offered by the design of the 0203 box gives a stronger box for safer transportation and storage. So if you need a custom box for heavyweight packaging, the FEFCO 0203 is the choice for you.
This is one of our folder-type custom boxes that is easy to wrap around the product and meets in the middle. The box is made out of one piece of cardboard and hinged. The ends of the box fold inside the box and will need to be secured with tape. This box is ideal as custom packaging for flat pack furniture products and uses such as boxes for books and paintings.
Our custom boxes are the perfect packaging solution for any number of box uses including product boxes, food boxes and shipping boxes.
Our high quality boxes are also eco friendly being 100% recyclable and 100% biodegradable. Here at Boxtopia we offer you a winning combination of excellent quality with a great service at an affordable price.
Our combination of three different types of box, with single or double walled corrugated cardboard and a choice of colours paired with customised sizing gives you a wide variety of boxes that will certainly fulfill your packaging requirements. Choosing the design, material and size will give you the bespoke boxes that you need.
We also offer custom box printing services. Printed packaging is a great opportunity for your brand to stand out from your competitors with packing boxes that will make an immediate impression on your customers.
